Radon release and dispersion from an open pit uranium mine  

SciTech Connect

Radon-222 flux from representative sections of the United Nuclear St. Anthony open-pit mine complex was measured. The collected radon was adsorbed on activated charcoal and the radon activity was measured by gamma spectroscopy. System design, calibration, and the procedure to determine radon flux density (pCi/m/sup 2/.s) are described. A continuous series of radon flux densities were measured over a 5-month period at a control point in the mine. The average flux density at the control point was 1.9 pCi/m/sup 2/.s. A close correlation between radon flux density variations and changes in barometric pressure was observed by a comparison of meteorological data and average daily radon flux density measured at the control point. The release rate from each section of the mine was calculated from the average radon flux density and the area of the section, as determined from enlarged aerial photographs. The average radon flux density for eight locations over the ore-bearing section was 7.3 pCi/m/sup 2/.s. The average flux density for four locations over undisturbed topsoil was 0.17 pCi/m/sup 2/.s. The average Ra-226 content of ten samples taken from the ore-bearing region was 102 pCi/g ore. The ratio of radon flux density to radium content (specific flux) was 0.072. The release rate from the entire St. Anthony open pit was determined to be 3.5 x 10/sup 5/ pCi/s. This rate is comparable to the natural release of radon from one square mile of undisturbed topsoil. 16 refs., 31 figs., 11 tabs.

Nature-oriented open coal mining technologies using mined-out space in an open-pit. Part II: A method for selecting rational sequence of mining flat dipping stratified deposits  

Science Conference Proceedings (OSTI)

A method is proposed for selecting a rational mining sequence with internal dumping for flat stratified deposits, using new principles of the open-pit process-space formation and development. The main criteria for substantiating the mining sequence are geometrical form and development direction of the open-pit space, structure of the working wall and transportation network, internal dumping capacities and mining earthworks volumes.

CHerenkov detectors In mine PitS (CHIPS) Letter of Intent to FNAL  

E-Print Network (OSTI)

This Letter of Intent outlines a proposal to build a large, yet cost-effective, 100 kton fiducial mass water Cherenkov detector that will initially run in the NuMI beam line. The CHIPS detector (CHerenkov detector In Mine PitS) will be deployed in a flooded mine pit, removing the necessity and expense of a substantial external structure capable of supporting a large detector mass. There are a number of mine pits in northern Minnesota along the NuMI beam that could be used to deploy such a detector. In particular, the Wentworth Pit 2W is at the ideal off-axis angle to contribute to the measurement of the CP violating phase. The detector is designed so that it can be moved to a mine pit in the LBNE beam line once that becomes operational.

Developing and evaluating pit truck safety devices  

SciTech Connect

Describes an electromagnetic system whereby smaller vehicles transmit a signal to haulage truck operators, to alert them to their presence. Driver visibility is restricted in large, rear-dump haulage trucks used in open-pit mining. Analysis shows the need for an alarm in the truck, to warn of vehicles in blind spots. As open-pit haulage truck size has increased, so has the size of the blind areas. Parameters for a prototype system included high- and low-frequency electromagnetic noise rejection, system sensitivity, ease of distance calibration, box size, mounting ease, power needs, and an internal system to continuously self-test all electronic fault-detection circuits. The prototype haulage truck cabmounted receiver had 2 channels. The system has been field-tested at the Twin Buttes open-pit mine near Tucson, AZ.

Shock airwaves in short-delayed blasting for open pit mining  

SciTech Connect

The authors discuss the choice of the optimum delay interval in terms of seismic and shock airwaves (SAW) intensity reduction during short-delayed blasting (SDB) of surface and hole blasts depending on the position of the charges relative to the objects being protected, such as the direction of detonation from charge to charge, etc. It was observed that during a short delayed blasting with a delay interval between groups of 50 m/sec, a complete separation of SAW pulses is produced by individual charges. Calculations also show that when blasting along a linear string of charges, the delay interval at which SAW pulses are fully separated depends on the direction at which detonation propogates.

Chapter 2: uranium mines and mills  

SciTech Connect

This chapter will be included in a larger ASCE Committee Report. Uranium mining production is split between underground and open pit mines. Mills are sized to produce yellowcake concentrate from hundreds to thousands of tons of ore per day. Miner's health and safety, and environmental protection are key concerns in design. Standards are set by the US Mine Safety and Health Administration, the EPA, NRC, DOT, the states, and national standards organizations. International guidance and standards are extensive and based on mining experience in many nations.

Uranium mining wastes, garden exhibition and health risks  

SciTech Connect

Available in abstract form only. Full text of publication follows: For more than 40 years the Soviet-German stockholding company SDAG WISMUT mined and milled Uranium in the East of Germany and became up to 1990 the world's third largest Uranium producer. After reunification of Germany, the new found state own company Wismut GmbH was faced with the task of decommissioning and rehabilitation of the mining and milling sites. One of the largest mining areas in the world, that had to be cleaned up, was located close to the municipality of Ronneburg near the City of Gera in Thuringia. After closing the operations of the Ronneburg underground mine and at the 160 m deep open pit mine with a free volume of 84 Mio.m{sup 3}, the open pit and 7 large piles of mine waste, together 112 Mio.m{sup 3} of material, had to be cleaned up. As a result of an optimisation procedure it was chosen to relocate the waste rock piles back into the open pit. After taking this decision and approval of the plan the disposal operation was started. Even though the transport task was done by large trucks, this took 16 years. The work will be finished in 2007, a cover consisting of 40 cm of uncontaminated material will be placed on top of the material, and the re-vegetation of the former open pit area will be established. When in 2002 the City of Gera applied to host the largest garden exhibition in Germany, Bundesgartenschau (BUGA), in 2007, Wismut GmbH supported this plan by offering parts of the territory of the former mining site as an exhibition ground. Finally, it was decided by the BUGA organizers to arrange its 2007 exhibition on grounds in Gera and in the valley adjacent to the former open pit mine, with parts of the remediated area within the fence of the exhibition.

Jackpile-Paguate Uranium Mine Reclamation Project, Laguna Indian Reservation, Cibola County, New Mexico  

SciTech Connect

Approval of a reclamation plan is proposed for the Jackpile-Paguate uranium mine, located on three leases of Laguna Indian tribal lands in Cibola County, 40 miles west of Albuquerque, New Mexico. The mine was operated by Anaconda Minerals Company from 1953 through early 1982. Of the total 7868 leased acres, 2656 acres were disturbed by mining. The disturbed areas include 3 open pits, 32 waste dumps, 23 protore (subgrade ore) stockpiles, 4 topsoil stockpiles, and 66 acres of buildings and roads. Three alternative plans are under consideration, involving different filling treatments of the open pits. Under Anaconda's proposal, the open pits would be backfilled to at least three feet above projected ground water recovery levels. The DOI plan would involve backfilling the pits with protore, excess material from waste dump resloping, and soil cover the elevations 40 to 70 feet higher than Anaconda's minimum. The pits then would remain as closed basins, or open channels would be constructed to convey runoff from the pit areas to the Rio Paguate. The Laguna proposal would consist of backfilling the pits seven feet above the DOI proposal. For all alternatives, highwall stability techniques would involve removal of loose material and buttressing with waste and overburden. Waste dump slopes would be reduced to between 2:1 and 3:1, and slopes could be terraced. Jackpile Sandstone exposed by resloping would be covered with four feet of overburden and one foot of topsoil. Mine site facilities would either be removed or cleaned up and left intact. All disturbed areas would be covered with topsoil and seeded. Reclamation would be considered complete when revegetated sites reached either 70% or 90% of that found on comparable reference sites. Post-reclamation monitoring periods would be 3, 5, or 10 years, depending on the alternative chosen. Cost estimates range from $54.2 million to $57.4 million.

Practice of overburden casting at the Trapper Mine - Craig, Colorado  

SciTech Connect

Enfield Pit was chosen to test overburden casting at the Trapper Mine in Colorado. Seam and overburden geology, and drilling and blasting patterns are described. Tables summarize the costs involved in cast blasting. The primary problem encountered was coal losses along the open face due to high powder factors and heave of the overburden. It was concluded that cast blasting has the potential of considerable savings in overburden stripping. 3 figures, 2 tables.

Selective mining and beneficiation at Grootegeluk coal mine Waterberg Coalfield, South Africa  

Science Conference Proceedings (OSTI)

Grootegeluk Coal Mine, situated in the Waterberg Coalfield in the Northern Province of South Africa, ranks among the largest open pit coal mines in the world in terms of run of mine tonnage. Commissioned in 1980 to provide steel producer Iscor with coking coal, Grootegeluk currently produces 53 Mt of coking coal per annum. At present Iscor consumes 1.2 Mt of coking coal while Matimba, the world's largest direct dry cooled PowerStation consumes an additional 12.6 Mt. Fine washing and screening plants currently beneficiate the run of mine feed from this multi-seam multi-product mine. Although the Waterberg Coalfield contains approximately 50% of South Africa's coal reserves, Grootegeluk is the only operating mine in this coalfield. The coal seams of the Waterberg Coalfield occur in the Volksrust and Vryheids formations of the Karoo Sequence. Numerous coal seams ranging from a few millimeters up to 8 meters occur over a stratigraphic thickness of at least 120 meters. These coal seams are grouped into eleven coal bearing zones that can be correlated across the coalfield. The coal- and coalbearing strata in the Waterberg are of late Paleozoic to early Mesozoic age. Coal from the Volksrust formation is autochthonous while the coal from the Vryheid formation is allochthonous. To ensure that sufficient geological and analytical data are obtained from exploration boreholes an extensive sampling procedure was established with washability data ranging from 1,35 to 2,20 g/cc. The analyses indicated that certain parts of the coalbearing strata is not suitable for the production of coking coal due to the high phosphorus content or the poor coking properties. This resulted in an open pit with 11 mining benches. The upper parts of the deposit is extracted by conventional shovel and truck operations while the coal seams of the lower part of the deposit are mined selectively with hydraulic shovels. At Grootegeluk down the hole geophysics (natural gamma) are used for grade control and also to quantify the effect of over- or undermining on the various mining benches. Reconciliation between the run of mine material dispatched to the various plants and their resulted yields/qualities are done regularly.

Midnite mine summary data (on CD-ROM). Data file  

SciTech Connect

This two-CD set is a compilation of most of the results of research conducted by the U.S. Bureau of Mines on the Midnite Mine in northeastern Washington state on the Spokane Indian Reservation. The site is an inactive open pit uranium mine for which reclamation research and planning is being performed. Hydrologic monitoring and modeling of contaminated and potentially contaminated groundwater at the mine was performed and results of these studies make up part of volume 1 of the CD set. Likewise, analyses of the mine wastes were performed to determine what materials could be used for reclamation and which would have to be remediated, and these data also are on volume 1. To support research activities at the site and to serve as a historical reference on what is known about the mine site, a GIS database was developed, including images of the site, topographic data, analytical data, and numerous other data sets that were available from government agencies and the mining company. Modeling of the site geology in 2D and 3D also was performed as part of GIS database development, and files from this research are included.

Remediation progress at the Iron Mountain Mine Superfund site, California. Information Circular/1991  

Science Conference Proceedings (OSTI)

The report was prepared by the U.S. Bureau of Mines to present a brief history of the listing of Iron Mountain Mine as a Superfund site on the National Priorities List (NPL) and subsequent remedial actions. The mine area is located on 4,400 acres near Redding, CA, and includes underground workings, an open pit area, waste rock dumps, and tailings piles. The property involves multiple sources of acid mine drainage (AMD) that are high in copper, zinc, and cadmium. The selected remedial actions, based on the Record of Decision of 1986, would partially cap the richmond mineralized zone to reduce infiltration of clean water, divert clean surface waters away from contaminated areas, fill surface subsidence areas, and enlarge the Spring Creek debris dam to provide increased surge capacity. Site remediation efforts at Iron Mountain are well into the remedial design-remedial action phase. Details of activities and designs of remedial elements are presented, and future activities, discussed.

Technology experience and economics of oil shale mining in Estonia  

Science Conference Proceedings (OSTI)

The exhaustion of fuel-energy resources became an evident problem of the European continent in the 1960s. Careful utilization of their own reserves of coal, oil, and gas (Germany, France, Spain) and assigned shares of imports of these resources make up the strategy of economic development of the European countries. The expansion of oil shale utilization is the most topical problem. The experience of mining oil shale deposits in Estonia and Russia, in terms of the practice and the economic results, is reviewed in this article. The room-and-pillar method of underground mining and the open-cut technology of clearing the ground ensure the fertility of a soil. The economics of underground and open pit oil shale mines is analyzed in terms of natural, organizational, and technical factors. These analyses are used in the planning and management of oil shale mining enterprises. The perspectives of the oil shale mining industry of Estonia and the economic expediency of multiproduction are examined. Recommendations and guidelines for future industrial utilization of oil shale are given in the summary.

Pit disassembly motion control  

Science Conference Proceedings (OSTI)

A Department of Energy (DOE) Pit Disassembly and Conversion Facility (PDCF) is being designed for the Savannah River Site in South Carolina. The facility will recover plutonium from excess nuclear weapon pits defined in START II and START III treaties. The plutonium will be stored and used to produce mixed oxide reactor fuel at another new DOE facility. Because of radiation dose issues, much of the pit disassembly work and material transfer will be automated. Automated material handling systems will interface with disassembly lathes, conversion reactors that produce oxide for storage, robotic container welding stations, vault retrieval systems, and nondestructive assay (NDA) instrumentation. The goal is to use common motion control hardware for material transfer and possibly common motion controllers for the unique PDCF systems. The latter is complicated by the different directions manufactures are considering for distributed control, such as Firewire, SERCOS, etc., and by the unique control requirements of machines such as lathes compared to controls for an integrated NDA system. The current design approach is to standardize where possible, use network cables to replace wire bundles where possible, but to first select hardware and motion controllers that meet specific machine or process requirements.

US uranium mining industry: background information on economics and emissions  

SciTech Connect

A review of the US uranium mining industry has revealed a generally depressed industry situation. The 1982 U/sub 3/O/sub 8/ production from both open-pit and underground mines declined to 3800 and 6300 tons respectively with the underground portion representing 46% of total production. US exploration and development has continued downward in 1982. Employment in the mining and milling sectors has dropped 31% and 17% respectively in 1982. Representative forecasts were developed for reactor fuel demand and U/sub 3/O/sub 8/ production for the years 1983 and 1990. Reactor fuel demand is estimated to increase from 15,900 tons to 21,300 tons U/sub 3/O/sub 8/ respectively. U/sub 3/O/sub 8/ production, however, is estimated to decrease from 10,600 tons to 9600 tons respectively. A field examination was conducted of 29 selected underground uranium mines that represent 84% of the 1982 underground production. Data was gathered regarding population, land ownership and private property valuation. An analysis of the increased cost to production resulting from the installation of 20-meter high exhaust borehole vent stacks was conducted. An assessment was made of the current and future /sup 222/Rn emission levels for a group of 27 uranium mines. It is shown that /sup 222/Rn emission rates are increasing from 10 individual operating mines through 1990 by 1.2 to 3.8 times. But for the group of 27 mines as a whole, a reduction of total /sup 222/Rn emissions is predicted due to 17 of the mines being shutdown and sealed. The estimated total /sup 222/Rn emission rate for this group of mines will be 105 Ci/yr by year end 1983 or 70% of the 1978-79 measured rate and 124 Ci/yr by year end 1990 or 83% of the 1978-79 measured rate.

Arm Pit Bacteria Arm Pit Bacteria Name: Kayla Location: N/A Country: N/A Date: N/A Question: I am doing a science fair project on deodorants and anti-perspirants- to see which one hinders bacterial growth more effectively. Here's my problem, I cannot find what kind of bacteria (mainly) flourishes in the axilla (armpit) region. I have been on many different search engines- medical pages- and microbiology pages, and unfortuantely cannot come up with any answers. My school's science fair is March 3rd- so I am in desperate need of an answer!!! I need to be able to order the type of bacteria soon. Thank you. Replies: Try Staphylococcus epidermidis-it is a common organism that grows on the skin. It is not pathogenic (disease-causing) and can be used by students. You could try culturing your own armpit-use a sterile q-tip. Spread the q-tip on the agar plate and then take some of your antiperspirant or deodorant and make a dot in the middle of the plate. Incubate the plate and see if the bacteria are repelled or are resistant. I would measure the size of the zone so you can compare each type of deodorant, etc. You could also check if different people's bacteria are more or less resistant, ie if the same deodorant works for everyone. Each person's bacterial population are a little different. This would require volunteers who would be willing to stick a q-tip in their armpit! If you decide to do this, I would sample the armpit when it is moist, before a shower (dry, clean skin won't have as much bacteria). Good luck.

Radiological impacts of Jackpile-Paguate uranium mines: an analysis of alternatives of decommissioning  

SciTech Connect

Potential pathways of radiation exposure and radiation-induced genetic and somatic effects from materials at the mine complex under five alternatives of decommissioning were analyzed using UDAD and PRIM computer codes. The principal pathways of exposure included in the analysis were inhalation of airborne radionuclides, ingestion of food and water containing radionuclides, and extended exposure to gamma and beta radiation from either airborne or ground-deposited radionuclides. The alternatives of decommissioning include (A) No Action (site will be fenced, otherwise left as it is), (B) No Future Use (site will be fenced and all disturbed area will be covered with 30 cm of soil, no grazing on the site); (C1) Grazing Land Use as developed by Anaconda Company (protore, waste piles, and open pits covered with 120 cm of soil, the remainder of the disturbed areas covered with 30 cm of soil, pits backfilled 90 cm above the equilibrium groundwater recovery level, no human habitation or farming allowed on the mine site, but grazing would be allowed); (C2) Grazing Land Use as developed by US Department of the Interior (similar to Alternative C1, but the pits covered with 300 cm of soil above the groundwater recovery level); and (D) Maximum Future Use (similar to Alternative C2, except construction of commercial and industrial facilities, storage, recreation, and further mining would be allowed). Radiation doses from atmospheric transport and ingestion of radionuclides were calculated, and somatic and genetic effects in individuals living within 80 km from the mine complex were predicted. Hydrological flow patterns in the mine area were analyzed to determine the potential for future contamination of surface water and groundwater and to determine the groundwater recovery level after reclamation, thus permitting incorporation of corrective actions into the reclamation procedures.

Systematic evaluation of satellite remote sensing for identifying uranium mines and mills.  

SciTech Connect

In this report, we systematically evaluate the ability of current-generation, satellite-based spectroscopic sensors to distinguish uranium mines and mills from other mineral mining and milling operations. We perform this systematic evaluation by (1) outlining the remote, spectroscopic signal generation process, (2) documenting the capabilities of current commercial satellite systems, (3) systematically comparing the uranium mining and milling process to other mineral mining and milling operations, and (4) identifying the most promising observables associated with uranium mining and milling that can be identified using satellite remote sensing. The Ranger uranium mine and mill in Australia serves as a case study where we apply and test the techniques developed in this systematic analysis. Based on literature research of mineral mining and milling practices, we develop a decision tree which utilizes the information contained in one or more observables to determine whether uranium is possibly being mined and/or milled at a given site. Promising observables associated with uranium mining and milling at the Ranger site included in the decision tree are uranium ore, sulfur, the uranium pregnant leach liquor, ammonia, and uranyl compounds and sulfate ion disposed of in the tailings pond. Based on the size, concentration, and spectral characteristics of these promising observables, we then determine whether these observables can be identified using current commercial satellite systems, namely Hyperion, ASTER, and Quickbird. We conclude that the only promising observables at Ranger that can be uniquely identified using a current commercial satellite system (notably Hyperion) are magnesium chlorite in the open pit mine and the sulfur stockpile. Based on the identified magnesium chlorite and sulfur observables, the decision tree narrows the possible mineral candidates at Ranger to uranium, copper, zinc, manganese, vanadium, the rare earths, and phosphorus, all of which are milled using sulfuric acid leaching.

Retaining latch for a water pit gate  

DOE Patents (OSTI)

The present invention relates to retaining devices which are used to latch two elements or parts together and, more particularly, to gate latches for use in locking a gate to a wall bracket in a water pit utilized to store or handle hazardous materials. A retaining latch is provided comprising a latch plate which is rotatably mounted to each end of the top of the gate and a recessed opening, formed in the gate frame, for engaging an edge of the latch plate. The latch plate is circular in profile with one side cut away or flat, such that the latch plate is D-shaped. The remaining circular edge of the latch plate comprises steps of successively reduced thickness. The stepped edge of the latch plate fits inside a recessed opening formed in the gate frame. As the latch plate is rotated, alternate steps of the latch plate are engaged by the recessed opening. When the latch plate is rotated such that the flat portion of the latch plate faces the recessed opening in the gate frame, there is no connection between the opening and the latch plate and the gate is unlatched from the gate frame.

Blasting to stabilize abandoned underground mines in eastern and midwestern coal fields: A feasibility study. Open File Report  

SciTech Connect

The study was designed to assist individuals involved with problem of abandoned mines that are subsiding. The study analyzed the practicality and desirability of using blasting to stabilize subsiding abandoned underground mines. Application of blasting to subsidence problems could provide a valuable alternative technology to classical methods of injecting fill material into abandoned mines to fill voids and prevent subsidence. By blasting, subsidence can be induced in a controlled manner, completed, and the site returned to its desired usage.

Getty mines oil sands in California  

Science Conference Proceedings (OSTI)

A large deposit of oil-laden diatomaceous earth in the McKittrick oil field 40 miles west of Bakersfield, California, has resisted all efforts at production by standard means. Getty Oil Co. is in the pilot phase of a project to recover the Diatomite's oil by an open pit mining operation. It also could have significant implications for other California oil fields, possibly setting the stage for the mining of oil sands in shallow fields like Kern River, S. Belridge, and Lost Hills to maximize oil recovery. A report on the project is summarized. The Diatomite is estimated to have 500 million bbl of oil in reserves, of which 380 million bbl are recoverable. The estimated amount of recoverable oil exceeds the McKittrick field's cumulative production of 240 million bbl. A pilot plant was built to test solvent extraction method of recovering heavy oil. The multistep process involves a series of 6 extractors. The Lurgi retorting plant employs a 2-step heating process to separate hydrocarbons from crushed ore.

Review and analysis of oil shale technologies. Volume I. Oil shale deposits, mining methods, and environmental concerns  

SciTech Connect

This volume describes and discusses oil shale deposits of the U.S., applicable methods for mining the shale, and the environmental concerns associated with oil shale technologies. Mining is required to supply shale to the retorts of aboveground processes. The majority of oil shale mining is expected to be by the underground room-and-pillar method. Surface mining (i.e., open pit mining) may also be used to supply material for surface retorts and may be appropriate for up to 15 to 20% of the oil shale resources. Principal environmental issues unique to true and modified in situ oil shale processing include disposal of retort water and drill cuttings, migration of fluids during and after in situ processing, surface thermal changes, and hazardous materials that may be leached from spent shale. Other site-specific problems of in situ processing include off-gas emissions, fugitive dust generation, land disturbance, and water usage. The environmental issues are similar for oil shale surface processes, except for surface thermal changes. The degree of impact, however, is expected greater than that for either the true or the modified in situ process.

Development of improved detection instruments for toxic gas contaminants in mining atmospheres. Open-file report, July 1979-January 1981  

SciTech Connect

Work has been carried out under a Bureau of Mines contract to develop and fabricate gas sensors for mining applications. Promising new instruments have been designed, developed, tested, and supplied to meet Bureau requirements. These instruments include prototype (1) remote-sensing, diffusion-type CO monitors for mine operation that can be operated in conjunction with a surface computer, (2) control modules for alternate in-mine readout of the remote diffusion type CO monitors, (3) personal CO diffusion-type dosimeters, and (4) personal NO diffusion-type dosimeters. In addition, retrofit modifications were made to update and optimize operation of CO and NO/sub 2/ direct-reading type detectors provided under a previous contract. Studies were conducted to evaluate and demonstrate the availability of stable, portable NO/sub 2/ calibration sources for NO/sub 2/ instrumentation. The use of selected, commercially available cylinder sources for NO/sub 2/ instrument calibration were recommended. Additional studies were also conducted to investigate the feasibility of instrumentation for rapidly monitoring CO, NO, and NO/sub 2/ in diesel exhaust.

Report on the survey of abandoned uraniferous lignite mines in southwestern North Dakota  

Science Conference Proceedings (OSTI)

A radiation survey was conducted in October 1983 as part of the proposed reclamation plan of abandoned uraniferous lignite mines in southwestern North Dakota. The survey was made to determine the extent of contamination caused by mining operations in the 1960's. Radiation measurements were made and soil samples were taken at approximately 300 locations around six mine sites comprising eleven lignite mine pits. Toxic element analysis was also done on 50 of the soil samples.

How to select an effective waste pit liner  

SciTech Connect

This article reports that the use of earthen pits is widespread in the oil and gas industry. These pits are used to contain produced water as well as waste fluids and solids from drilling activities. The pits contain a myriad of metals, salts, minerals and organic compounds. Sometimes, a pit liner may be needed to ensure the integrity of the earthen pit. The pit liner should act as an impervious barrier between the contained fluids and soil or ground water outside the pit. It is imperative to construct the pit and liner to prevent leakage of pit contents and consequent potential contamination of the surrounding environment. In the United States, the construction of oilfield pits and the need for pit liners is typically governed by state oil and gas regulatory requirements. Standards for the construction and composition of pit liners vary considerably from state to state. Thus, when choosing a pit liner or constructing an oilfield waste pit, it is important to determine the legal requirements applicable in the state where the pit is located.

Contamination of ground and surface waters due to uranium mining and milling. Volume I: Biological processes for concentrating trace elements from uranium mine waters. Open file report 25 Jul 79-14 Sep 81  

Science Conference Proceedings (OSTI)

Wastewater from uranium mines in the Ambrosia Lake district near Grants, N. Mex., contains uranium, selenium, radium, and molybdenum. A novel treatment process for waters from two mines, sections 35 and 36, to reduce the concentrations of the trace contaminants was developed. Particulates are settled by ponding and the waters are passed through an ion exchange resin to remove uranium; barium chloride is added to precipitate sulfate and radium from the mine waters. The mine waters are subsequently passed through three consecutive algae ponds prior to discharge. Water, sediment, and biological samples were collected over a 4-year period and analyzed to assess the role of biological agents in removal of inorganic trace contaminants from the mine waters.

Thermal analysis of simulated Pantex pit storage  

Science Conference Proceedings (OSTI)

This report investigates potential pit storage configurations that could be used at the Mason and Hanger Pantex Plant. The study utilizes data from a thermal test series performed at Lawrence Livermore National Laboratory (LLNL) that simulated these storage configurations. The heat output values used in the LLNL test series do not represent actual pits but are rounded numbers that were chosen for convenience to allow parameter excursions. Specifically in this project, we are modeling the heat transfer and air flow around cylindrical storage containers in Pantex magazines in order to predict container temperatures. This difficult problem in thermal- fluid mechanics involves transient, three-dimensional (3-D) natural convection and thermal radiation around interacting containers with various heat generation rates. Our approach is to link together two computational methods in order to synthesize a modeling procedure for a large array of pit storage containers. The approach employs a finite element analysis of a few containers, followed by a lumped- parameter model of an array of containers. The modeling procedure we developed was applied in the simulation of a recent experiment where temperatures of pit storage containers were monitored in a steady- state, controlled environment. Our calculated pit container temperatures are comparable with data from that experiment. We found it absolutely necessary to include thermal radiation between containers in order to predict temperatures accurately, although the assumption of black-body radiation appears to be sufficient. When radiation is neglected the calculated temperatures are 4 to 6 {degrees}C higher than temperature data from the experiment. We also investigated our model`s sensitivity to variations in the natural convection heat transfer coefficient and found that with a 50% drop in the coefficient, calculated temperatures are approximately I {degree}C higher. Finally, with a modified lumped-parameter model, we demonstrate how an entire Pantex magazine can be simulated.

Low productivity in American coal mining: causes and cures. Report to the Congress  

SciTech Connect

The report identifies the factors responsible for depressed productivity in the U.S. coal mining industry. GAO analysis revealed that the fall in underground mining productivity since 1969 is closely tied to poor labor-management relations, 1974 union contract requirements, and Federal mine safety and health regulations. State reclamation laws and the opening of new surface mines lowered productivity in surface mining. Coal mining technology has not advanced sufficiently to offset the loss due to these causes.

Lignite mine spoil characterization and approaches for its rehabilitation  

SciTech Connect

Open cast mining of lignite leaves behind stockpiles of excavated materials (dumps) and refilled mining pits (spoils). Physicochemical and biochemical properties of both kinds of sites were estimated to identify the reasons for their barrenness. Subsequently, surface modifications were attempted, first in a greenhouse and later infield to develop a suitable approach for their rehabilitation. Dumps had low pH (4.8) and high Na{sup +} (2.5 mg g{sup -1}), spoils high pH (8.7) and high Na{sup +} (1.59 mg g{sup -1} soil). Both sites had low available nitrogen and phosphorus and showed very low dehydrogenase and phosphatases activity but no nitrification. The extreme physicochemical conditions and inert nature of damps and spoils explained their barrenness. In the greenhouse experiment, 14 plant species sown in surface materials of dumps and spoils after spreading a 0.15 m thick layer of dune sand, germinated ({gt}85%), and their seedlings survived for two months. This technique was followed at a spoil site (modified spoil site). After three years of stabilization the modified spoil site had only one-fifth Na{sup +} of that in spoil surface in the beginning and also showed higher dehydrogenase and phosphatase activity and nitrification. Pearl millet and Cenchrus ciliaris grown in modified spoil produced 128 to 394 kg and 2.25 to 3.50 Mg dry matter ha{sup -1}. Addition of farmyard manure with N and P fertilizers increased pearl millet yields.

Introduction to Pits and Weapons Systems (U)  

Science Conference Proceedings (OSTI)

A Nuclear Explosive Package includes the Primary, Secondary, Radiation Case and related components. This is the part of the weapon that produces nuclear yield and it converts mechanical energy into nuclear energy. The pit is composed of materials that allow mechanical energy to be converted to electromagnetic energy. Fabrication processes used are typical of any metal fabrication facility: casting, forming, machining and welding. Some of the materials used in pits include: Plutonium, Uranium, Stainless Steel, Beryllium, Titanium, and Aluminum. Gloveboxes are used for three reasons: (1) Protect workers and public from easily transported, finely divided plutonium oxides - (a) Plutonium is very reactive and produces very fine particulate oxides, (b) While not the 'Most dangerous material in the world' of Manhattan Project lore, plutonium is hazardous to health of workers if not properly controlled; (2) Protect plutonium from reactive materials - (a) Plutonium is extremely reactive at ambient conditions with several components found in air: oxygen, water, hydrogen, (b) As with most reactive metals, reactions with these materials may be violent and difficult to control, (c) As with most fabricated metal products, corrosion may significantly affect the mechanical, chemical, and physical properties of the product; and (3) Provide shielding from radioactive decay products: {alpha}, {gamma}, and {eta} are commonly associated with plutonium decay, as well as highly radioactive materials such as {sup 241}Am and {sup 238}Pu.

Data mining  

Science Conference Proceedings (OSTI)

This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The objective of this project was to develop and implement data mining technology suited to the analysis of large collections of unstructured data. This has taken the form of a software tool, PADMA (Parallel Data Mining Agents), which incorporates parallel data accessing, parallel scalable hierarchical clustering algorithms, and a web-based user interface for submitting Structured Query Language (SQL) queries and interactive data visualization. The authors have demonstrated the viability and scalability of PADMA by applying it to an unstructured text database of 25,000 documents running on an IBM SP2 at Argonne National Laboratory. The utility of PADMA for discovering patterns in data has also been demonstrated by applying it to laboratory test data for Hepatitis C patients and autopsy reports in collaboration with the University of New Mexico School of Medicine.

Recolonization of surface-mined lands by pocket gophers (Geomys breviceps) in East Texas Post Oak Savannah  

E-Print Network (OSTI)

Surface mining involves the use of heavy equipment that would theoretically create underground vibrations sensed by pocket gophers. To determine if vibrations cause pocket gopher movement away from areas being mined, gopher movements were monitored in a hay field adjacent to an active mine pit on Big Brown Mine in Freestone County, Texas. Gophers were live-trapped in summer 2000 prior to mining activity, injected subcutaneously with a passive integrated transponder (PIT) tag, and released. Coordinates of each capture location were recorded. After mining began and spoil piles were established adjacent to the field, re-trapping was conducted. Upon capture each pocket gopher was scanned for a PIT tag and newly caught animals were tagged. Location coordinates were recorded to determine movement between capture sites. Of the 58 gophers captured and tagged, 9 individuals were recaptured. Pocket gophers did not appear to move away from mining activity, so they might have been adversely affected. However, the number of individuals in the population remained constant during the study, indicating there was no population effect. During January and February 2001, all remaining non-mined and reclaimed lands within the mine were surveyed for pocket gopher activity (mounds). Activity was found on non-mined land adjacent to reclaimed land but no activity was found on reclaimed land. Pocket gopher populations did not reestablish on reclaimed lands because of the removal of sandy soils and subsequent replacement with hard, loamy soils. If pocket gophers are desired on reclaimed lands, then it would be important to retain areas of topsoil containing at least 80% sand.

Demonstration of In-Situ Stabilization of Buried Waste at Pit G-11 at the Brookhaven National laboratory Glass Pits Disposal Site  

Science Conference Proceedings (OSTI)

In 1989 BNL was added to the EPAs National Priorities List. The site is divided into seven operable units (OU). OU-I includes the former landfill area. The field task site is noted as the AOC 2C Glass Holes location. Beginning in the 1960s and continuing into the 1980s, BNL disposed of laboratory waste (glassware, chemicals and animal carcasses) in numerous shallow pits. The drivers for remediating the pits are; historical records that indicate hazardous materials may have been disposed of in the pits; ground water contamination down gradient of the pits; a test excavation of one of the glass holes that unearthed laboratory glass bottles with unidentified liquids still contained; and the fact that BNL rests atop an EPA designated sole-source aquifer. The specific site chosen for this demonstration was pit G-11. The requirements that lead to choosing this pit were; a well characterized pit and a relatively isolated pit where our construction operations would not impact on adjacent pits. The glass holes area, including pit G-11, was comprehensively surveyed using a suite of geophysical techniques (e.g., EM-31, EM-61, GPR). Prior to stabilizing the waste form a subsurface barrier was constructed to contain the entire waste pit. The pit contents were then stabilized using a cement grout applied via jet grouting. The stabilization was performed to make removal of the waste from the pit easier and safer in terms of worker exposure. The grouting process would mix and masticate the waste and grout and form a single monolithic waste form. This large monolith would then be subdivided into smaller 4 foot by 4 foot by 10-12 foot block using a demolition grout. The smaller blocks would then be easily removed from the site and disposed of in a CERCLA waste site.

Metallography of pitted aluminum-clad, depleted uranium fuel  

Science Conference Proceedings (OSTI)

The storage of aluminum-clad fuel and target materials in the L-Disassembly Basin at the Savannah River Site for more than 5 years has resulted in extensive pitting corrosion of these materials. In many cases the pitting corrosion of the aluminum clad has penetrated in the uranium metal core, resulting in the release of plutonium, uranium, cesium-137, and other fission product activity to the basin water. In an effort to characterize the extent of corrosion of the Mark 31A target slugs, two unirradiated slug assemblies were removed from basin storage and sent to the Savannah River Technology Center for evaluation. This paper presents the results of the metallography and photographic documentation of this evaluation. The metallography confirmed that pitting depths varied, with the deepest pit found to be about 0.12 inches (3.05 nun). Less than 2% of the aluminum cladding was found to be breached resulting in less than 5% of the uranium surface area being affected by corrosion. The overall integrity of the target slug remained intact.

Status of the Pit Disassembly and Conversion Facility  

Science Conference Proceedings (OSTI)

A planned new facility, the Pit Disassembly and Conversion Facility (PDCF) will be used to disassemble the nation`s inventory of surplus nuclear weapons pits and convert the plutonium recovered from those pits into a form suitable for storage, international inspection, and final disposition. Sized to handle 35 metric tons of plutonium from pits and other sources over its 10-year operating life, the PDCF will apply the Advanced Recovery and Integrated Extraction System (ARIES) technology. ARIES process technology has been developed at Los Alamos National Laboratory (LANL) and Lawrence Livermore National Laboratory (LLNL) and an integrated system is being demonstrated LANL. Four sites were considered for locating the PDCF: Pantex Plant, Savannah River Site (SRS), Idaho National Engineering and Environmental Laboratory (INEEL), and Hanford Site. Each site offers a different opportunity for constructing the PDCF, ranging from a new building at Pantex Plant to using an existing building at Hanford Site or INEEL. The Surplus Plutonium Disposition Environmental Impact Statement was prepared by the Department of Energy (DOE) Office of Fissile Materials Disposition (OFMD) to aid in site selection. This paper describes the initial scoping activities, preconceptual and conceptual design work, and the status of the PDCF.

Integrating Safeguards into the Pit Disassembly and Conversion Facility  

SciTech Connect

In September 2000, the United States and the Russian Federation entered into an agreement which stipulates each country will irreversibly transform 34 metric tons of weapons-grade plutonium into material which could not be used for weapon purposes. Supporting the Department of Energy's (DOE) program to dispose of excess nuclear materials, the Pit Disassembly and Conversion Facility (PDCF) is being designed and constructed to disassemble the weapon ''pits'' and convert the nuclear material to an oxide form for fabrication into reactor fuel at the separate Mixed Oxide Fuel Fabrication Facility. The PDCF design incorporates automation to the maximum extent possible to facilitate material safeguards, reduce worker dose, and improve processing efficiency. This includes provisions for automated guided vehicle movements for shipping containers, material transport via automated conveyor between processes, remote process control monitoring, and automated Nondestructive Assay product systems.

PitPro 1.1 User's Manual; Pit-tag to SURPH Data Translation Utility, Technical Manual 2003.  

DOE Green Energy (OSTI)

This manual describes the use of Program PitPro to convert PIT-tag data files in PTAGIS (PIT Tag Information System, Pacific States Marine Fisheries Commission) to input files ready for survival analysis in Program SURPH 2.1. This utility converts the various PIT-tag detections at the multitude of detector coils within a juvenile bypass or at adult counting windows and ladders into capture histories. The capture histories indicate whether a tagged fish was detected, not detected, or detected and censored at the major hydroprojects in the Columbia Basin. A major update to this program is the inclusion of adult upstream detection histories. Adult detection histories include not only whether the fish was detected or not but also the year of detection for proper adult survival estimation. The SURPH program is a valuable tool for estimating survival and detection probabilities of fish migrating in the Snake and Columbia rivers. Using special input data files, SURPH computes reach-to-reach statistics for any release group passing a system of detection sites. However, PIT-tag data, as available from PTAGIS, comes in a form that is not ready for use as SURPH input. SURPH requires a capture history for each fish. A capture history consists of a series of fields, one for each detection site, that has a code for whether the fish was detected and returned to the river, detected and removed, or not detected. The data, as received from PTAGIS, has one line for each detection with information such as fish identification (id), detection date and time, number of coil hits and detector coil ids, etc. Because an individual fish may be detected at several coils within a detection site as well as at several detection sites, each fish is often represented by multiple lines in the PTAGIS data file. For the PTAGIS data to be usable by SURPH, it must be preprocessed. The data must be condensed down to one line per fish with the relevant detection information from the PTAGIS file represented compactly on each line. In addition, the PTAGIS coil information must be passed through a series of logic algorithms to determine whether or not a fish was returned to the river after detection. Program PitPro was developed to allow the user to properly preprocess the PTAGIS data files for input to program SURPH through a user friendly graphical user interface (GUI). This utility takes PTAGIS data files as input and creates a SURPH data file as well as other output including travel time records, detection date records, and a data error file. PitPro allows a user to download PTAGIS files and easily process the data for use with SURPH. Program PitPro is based on the command line utility CaptHist.

Explanation of Significant Difference (ESD) for the A-Area Burning/Rubble Pits (731-A/1A) and Rubble Pit (731-2A) (U)  

DOE Green Energy (OSTI)

The A-Area Burning/Rubble Pits (731-A/1A) and Rubble Pit (731-2A) (ABRP) operable unit (OU) is located in the northwest portion of Savannah River Site (SRS), approximately 2.4 kilometers (1.5 miles) south of the A/M Area operations. Between 1951 and 1973, Pits 731-A and 731-1A were used to burn paper, plastics, wood, rubber, rags, cardboard, oil, degreasers, and solvents. Combustible materials were burned monthly. After burning was discontinued in 1973, Pits 731-A and 731-1A were also converted to rubble pits and used to dispose of concrete rubble, bricks, tile, asphalt, plastics, metal, wood products, and rubber until about 1978. When the pits were filled to capacity, there were covered with compacted clay-rich native soils and vegetation was established. Pit 731-2A was only used as a rubble pit until 1983 after which the area was backfilled and seeded. Two other potential source areas within the OU were investigated and found to be clean. The water table aquifer (M-Area aquifer) was also investigated.

European coal mining technology  

SciTech Connect

Most new developments in mechanized longwall coal technology have been pioneered by European mines and equipment manufacturers. But ironically, the most successful adaptations of European-inspired longwalling systems have occurred in North America, Australia, South Africa and elsewhere, enabling those mines to achieve even greater productivity and cost-effective utilization than the Europeans enjoy. This anomaly has little to do with mining talents, but arises instead from a pair of factors: 1) the extremely difficult mining and geological conditions of European coal basins; and 2) the profound differences between the management style and operating routines of the largely state-owned mines of Europe and the privately-owned, profit oriented mining companies abroad. Nevertheless, Europe continues to lead the way in new developments, driven by the chemistry of tough mining conditions and the commitments of its national mining industries to invest in new technology. As a third ingredient, the supra-national European Economic Community (EEC) plays an important role in promoting and funding new developments through its various agencies. A recent EEC information symposium on new methods of coal winning at Luxembourg focused on state-of-the-art longwall technology. Thus a look at current Euopean RandD programs yields pointers as to what the international coal industry may expect in the future.

The effects of the topographic bench on ground motion from mining explosions  

Science Conference Proceedings (OSTI)

Understanding the effects of the bench on ground motion can improve the design of cast blasts and achieve improved blast efficiency while remaining below vibration requirements. A new dataset recorded in September 2003 from a coal mine in Arizona has allowed us to examine the excitation of short-period Rayleigh-type surface waves from four simultaneously-detonated explosions in and below a topographic bench of a mine. The explosions were recorded on a network of over 150 seismic sensors, providing an extensive understanding of the ground motion radiation patterns from these explosions. We detonated two separate explosions in the deepest pit of the mine, thus the explosions were shot to solid rock. Within 25 meters of these two explosions, we detonated two additional explosions of similar explosive yields in a bench, thus these explosions were shot to the free face. Radiation patterns and spectral ratios from the explosions show increased amplitudes at azimuths behind the bench relative to the amplitudes in front of the bench. We compared these findings to seismic observations from two {approximately} 1.5 million pound cast blasts at the same mine and found similar radiations patterns. Modeling of these blasts shows that the variations in ground motion are caused by the topographic bench as a result of 1) horizontal spalling of the rock falling into the pit and 2) non-linear scattering near the free-face. Shooting to a buffer also causes the azimuthal variations to be significantly reduced.

Evaluation of the fire and explosion hazards of oil-shale mining and processing. Volume 1. Analytical studies and accident scenarios. Open file report, 16 June 1977-15 July 1983  

SciTech Connect

The objectives of this research were to identify and evaluate potential fire and explosion hazards in oil-shale mining and processing by laboratory testing to provide recommendations for mitigation safety monitoring and to establish a basis for regulation. A series of scenarios were developed describing hypothetical fire and explosion incidents that might occur in oil-shale mining. The objectives were achieved through the following accomplishments: (1) It was found that fire and explosion properties of oil shale increase with oil shale richness and decreasing particle size. (2) Data from dust loading study in several mines showed that the total potential yield of combustibles was about one-tenth the amount required to fuel a propagating explosion. (3) Aging of oil shale dusts over a period of several years reduces the content of volatile combustibles and the corresponding fire and explosion properties. (4) Data and information from the completed program indicate that the hazard of dust explosions is less severe than the hazard of fire in mine muck piles. Laboratory data were used to relate fire and explosivity properties of oil shales to those of coals and other carbonaceous materials and to assist in the identification and evaluation of potential hazardous situations that may be encountered in oil shale mining and processing.

Corrective Action Investigation Plan for Corrective Action Unit 234: Mud Pits, Cellars, and Mud Spills, Nevada Test Site, Nevada, Revision 0  

SciTech Connect

Corrective Action Unit 234, Mud Pits, Cellars, and Mud Spills, consists of 12 inactive sites located in the north and northeast section of the NTS. The 12 CAU 234 sites consist of mud pits, mud spills, mud sumps, and an open post-test cellar. The CAU 234 sites were all used to support nuclear testing conducted in the Yucca Flat and Rainier Mesa areas during the 1950s through the 1970s. The CASs in CAU 234 are being investigated because hazardous and/or radioactive constituents may be present in concentrations that could potentially pose a threat to human health and the environment. Existing information on the nature and extent of potential contamination is insufficient to evaluate and recommend corrective action alternatives for the CASs. Additional information will be generated by conducting a CAI before evaluating and selecting appropriate corrective action alternatives.

Giant weathering pits in the Entrada Sandstone, southeastern Utah: Preliminary findings  

SciTech Connect

Giant weathering pits formed in outcrops of the lower Entrada Sandstone slickrock of Jurassic age are present in two areas in the Glen Canyon region of arid southeastern Utah. The pits are far larger than any previously described in the geologic literature. The pits near Cookie Jar Butte are commonly cylindrical, typically have low width-to-depth ratios (1.5--3.6), and have a depth of closure of as much as 18 m. There are no obvious lithologic or structural controls that determine their shape or location. Many of the pits at Rock Creek Bay are elongate; several of them have long axes in excess of 53 m, and the longest one is 74 m. Many of the pit walls are breached at the top, and the depth of closure is generally less than 6 m. The shapes of these pits are influenced by point orientation and pit coalescence. Thin-section analyses of near-surface sandstone cores taken near Cookie Jar Butte from pit walls, floors, and rims reveal no significant diagenetic alteration of the fine-grained to very fine frained quartzose sandstone (quartz arenite). Quartz grains appear fresh, and feldspar grains are only slightly weathered. The cement between the grains is mostly CaCO[sub 3]. In several of the pits in both areas sandy sediment veneers the bedrock floor. This sediment is similar in character to the adjacent sandstone and is probably locally derived. Possible origins of the giant pits include various physical, chemical, and biological weathering processes that initiate pit development, followed by excavation by plunge-pool action, wind deflation, dissolution, and piping. Preliminary field and laboratory data do not clearly identify and single process of group of processes that account for pit development.

Method to prevent/mitigate steam explosions in casting pits  

SciTech Connect

Steam explosions can be prevented or mitigated during a metal casting process by the placement of a perforated flooring system in the casting pit. An upward flow of compressed gas through this perforated flooring system is introduced during the casting process to produce a buffer layer between any spilled molten metal and the cooling water in the reservoir. This buffer layer provides a hydrodynamic layer which acts to prevent or mitigate steam explosions resulting from hot, molten metal being spilled into or onto the cooling water.

Uranium Mining and Enrichment  

NLE Websites -- All DOE Office Websites (Extended Search)

Overview Presentation » Uranium Mining and Enrichment Overview Presentation » Uranium Mining and Enrichment Uranium Mining and Enrichment Uranium is a radioactive element that occurs naturally in the earth's surface. Uranium is used as a fuel for nuclear reactors. Uranium-bearing ores are mined, and the uranium is processed to make reactor fuel. In nature, uranium atoms exist in several forms called isotopes - primarily uranium-238, or U-238, and uranium-235, or U-235. In a typical sample of natural uranium, most of the mass (99.3%) would consist of atoms of U-238, and a very small portion of the total mass (0.7%) would consist of atoms of U-235. Uranium Isotopes Isotopes of Uranium Using uranium as a fuel in the types of nuclear reactors common in the United States requires that the uranium be enriched so that the percentage of U-235 is increased, typically to 3 to 5%.

Low productivity in American coal mining: causes and cures  

SciTech Connect

This report identifies the factors responsible for depressed productivity in the US coal mining industry. GAO analysis revealed that the fall in underground mining productivity since 1969 is closely tied to poor labor-management relations, 1974 union contract requirements, and federal mine safety and health regulation. State reclamation laws and the opening of new surface mines lowered productivity in surface mining. Coal mining technology has not advanced sufficiently to offset the loss due to these causes. Federal and state regulations have been successful in reducing both fatalities and the environmental costs of coal mining. Thus far, lower productivity is a price the nation has paid for imposed health, safety, and environmental regulations. Industry and public officials must find ways to offset the effects of regulation on productivity without compromising safety or environmental quality. GAO recommends increased federal efforts to promote the development and greater use of safe, productivity technologies, and improved labor management relations. Because of the importance of higher productivity, GAO plans to send the report to knowledgeable individuals to solicit their views on the report's conclusions, and to request suggestions on how they might be implemented. If appropriate, GAO will submit further recommendations in a subsequent report.

Results of deep exploratory drilling between long and Newark Valleys, White Pine County, Nevada - implications for oil migration in the nearby Yankee gold mine paleohydrothermal system  

Science Conference Proceedings (OSTI)

In mid-1992, a consortium headed by Pioneer Oil and Gas (Midvale, Utah) drilled a deep (6700 ft) exploratory well in the southern Ruby Mountains-Buck Mountain are near the Alligator Ridge mining district in White Pine County, Nevada. The test well is located 1.5 mi southwest of USMX, Inc.'s, Yankee gold mine, an open-pit operation centered on a Carlin-type, sediment-hosted gold orebody noteworthy for containing abundant, fracture-controlled live oil. The Pioneer well as dry, but intersected much of the same stratigraphic section hosting gold at Yankee, thereby providing valuable clues to mechanisms of oil migration at this unusual, oil-bearing precious-metal deposit. Most of the gold at Yankee is hosted by the Devonian Pilot Shale, with a basal argillaceous limestone containing the bulk of the deposit's live oil. The equivalent section in the Pioneer wildcat well is a silty calcareous dolomite. Whereas the basal Pilot limestone at Yankee is rich in thick, locally gold- and arsenic-anomalous calcite veins and modules hosting abundant oil-bearing fluid inclusion, the basal Pilot dolomite in the Pioneer well contains only a few thin calcite-pyrite veinlets devoid of fluid inclusions. Moreover, the Yankee calcite veins have the same light-stable-isotope signatures as hydrothermal carbonate veins near or elsewhere in the Alligator Ridge district. These relationships imply that oil at Yankee migrated in the same hydrothermal system responsible for gold mineralization. Such systems elsewhere in the eastern Basin and Range, given favorable source rocks, traps, seals, and migratory pathways, might well have formed not only gold deposits, but also rich, spatially coincident oil reservoirs.

High Rate Laser Pitting Technique for Solar Cell Texturing  

SciTech Connect

High rate laser pitting technique for solar cell texturing Efficiency of crystalline silicon solar cells can be improved by creating a texture on the surface to increase optical absorption. Different techniques have been developed for texturing, with the current state-of-the-art (SOA) being wet chemical etching. The process has poor optical performance, produces surfaces that are difficult to passivate or contact and is relatively expensive due to the use of hazardous chemicals. This project shall develop an alternative process for texturing mc-Si using laser micromachining. It will have the following features compared to the current SOA texturing process: -Superior optical surfaces for reduced front-surface reflection and enhanced optical absorption in thin mc-Si substrates -Improved surface passivation -More easily integrated into advanced back-contact cell concepts -Reduced use of hazardous chemicals and waste treatment -Similar or lower cost The process is based on laser pitting. The objective is to develop and demonstrate a high rate laser pitting process which will exceed the rate of former laser texturing processes by a factor of ten. The laser and scanning technologies will be demonstrated on a laboratory scale, but will use inherently technologies that can easily be scaled to production rates. The drastic increase in process velocity is required for the process to be implemented as an in-line process in PV manufacturing. The project includes laser process development, development of advanced optical systems for beam manipulation and cell reflectivity and efficiency testing. An improvement of over 0.5% absolute in efficiency is anticipated after laser-based texturing. The surface textures will be characterized optically, and solar cells will be fabricated with the new laser texturing to ensure that the new process is compatible with high-efficiency cell processing. The result will be demonstration of a prototype process that is suitable for scale-up to a production tool and process. The developed technique will have an reducing impact on product pricing. As efficiency has a substantial impact on the economics of solar cell production due to the high material cost content; in essence, improved efficiency through cost-effective texturing reduces the material cost component since the product is priced in terms of $/W. The project is a collaboration between Fraunhofer USA, Inc. and a c-Si PV manufacturer.

Laboratory program to examine effects of layup conditions on pitting of Alloy 600. Final report. [PWR  

Science Conference Proceedings (OSTI)

The effect of various layup conditions on pitting of Alloy 600 tubing for steam generators was studied in beaker tests at 40/sup 0/C (104/sup 0/F). In addition, several methods to inhibit pitting were studied. The pitting solutions studied were copper chloride or seawater plus simulated sludge containing copper, copper oxide and magnetite. Results show that the pitting of Alloy 600 initiated in less than three weeks in the copper chloride solution with about 700 ppM chloride present. The same results were obtained in the seawater solution with about 6000 ppM chloride present. Retardation of pitting was achieved in three different ways: (1) decreasing the oxygen content of the solution, (2) decreasing the copper content of the solution, and (3) increasing the pH of the solution.

Double contingency controls in the pit disassembly and conversion facility  

Science Conference Proceedings (OSTI)

A Pit Disassembly and Conversion Facility (PDCF) will be built and operated at DOE'S Savannah River Site (SRS) in South Carolina. The facility will process over three metric tons of plutonium per year. There will be a significant amount of special nuclear material (SNM) moving through the various processing modules in the facility, and this will obviously require well-designed engineering controls to prevent criticality accidents. The PDCF control system will interlock glovebox entry doors closed if the correct amount of SNM has not been removed from the exit enclosure. These same engineering controls will also be used to verify that only plutonium goes to plutonium processing gloveboxes, enriched uranium goes to enriched uranium processing, and that neither goes into non-SNM processing gloveboxes.

Evaluation of a geothermal well logging, DST and Pit test  

DOE Green Energy (OSTI)

This paper briefly discusses logging and testing operations and certain related physical aspects in geothermal well evaluations. A good understanding of thermal and hydrological characteristics of geothermal reservoirs are essential in geothermal well evaluations. Within geothermal reservoirs, in evaluating the wells, the two most important parameters that first could be estimated, then measured or calculated, are temperature and productivity. Well logs and wireline surveys are means of measuring formation temperatures. Drill Stem Tests (DST's) or Pit Tests are means of determining formation productivity. Geochemistry and Petrology are currently accepted as two evaluation yardsticks in geothermal well evaluations. investigations of cuttings and cores during drilling operations, along with studies on formation waters could be used in a predictive nature for temperature and productivity and could yield useful information on the resource.

Remedial Action Work Plan Amchitka Island Mud Pit Closures  

Science Conference Proceedings (OSTI)

This remedial action work plan presents the project organization and construction procedures developed for the performance of the remedial actions at U.S. Department of Energy (DOE's) sites on Amchitka Island, Alaska. During the late1960s and early 1970s, the U.S. Department of Defense and the U.S. Atomic Energy Commission (the predecessor agency to DOE) used Amchitka Island as a site for underground nuclear tests. A total of nine sites on the Island were considered for nuclear testing; however, tests were only conducted at three sites (i.e., Long Shot in 1965, Milrow in 1969, and Cannikin in 1971). In addition to these three sites, large diameter emplacement holes were drilled in two other locations (Sites D and F) and an exploratory hole was in a third location (Site E). It was estimated that approximately 195 acres were disturbed by drilling or preparation for drilling in conjunction with these activities. The disturbed areas include access roads, spoil-disposal areas, mud pits which have impacted the environment, and an underground storage tank at the hot mix plant which was used to support asphalt-paving operations on the island. The remedial action objective for Amchitka Island is to eliminate human and ecological exposure to contaminants by capping drilling mud pits, removing the tank contents, and closing the tank in place. The remedial actions will meet State of Alaska regulations, U.S. Fish and Wildlife Service refuge management goals, address stakeholder concerns, and address the cultural beliefs and practices of the native people. The U.S. Department of Energy, Nevada Operations Office will conduct work on Amchitka Island under the authority of the Comprehensive Emergency Response, Compensation, and Liability Act. Field activities are scheduled to take place May through September 2001. The results of these activities will be presented in a subsequent Closure Report.

Risk analysis of shipping plutonium pits and mixed oxide fuel  

E-Print Network (OSTI)

With the end of the cold war, there no longer seems to be a credible threat of war between nuclear superpowers, with its possible consequence of billions of fatalities. However, the residue of the cold war, most notably the now excess weapons plutonium, has been identified as the source of a number of potential catastrophes. For example, just a single crude nuclear weapon in the hands of a terrorist organization or rogue state and detonated in even a medium-sized city could lead to hundreds of thousands of deaths. For this reason, the ultimate disposition of this excess plutonium has been identified as a national priority. The process of carrying out this disposition itself carries some risks, and even though any conceivable consequences clearly will be much smaller in magnitude than those cited above, U.S. federal law (the National Environmental Protection Act) mandates that such risks must be analyzed. The ability to carry out one type of such an analysis is demonstrated in this thesis. Specifically, one possible option that has been identified for disposition of excess U.S. weapons plutonium is the transformation into mixed oxide (MOX) fuel, that then would be used as fuel in a commercial nuclear power plant. Any such process will involve the transportation of the MOX fuel from the MOX fuel fabrication facility to the nuclear power plant, and possibly transportation of the plutonium from a storage site to the fuel fabrication facility. This thesis is intended to demonstrate the capability to analyze the risks associated with such transportation campaigns. The primary tool used for these analyses was RADTRAN, a code developed by Sandia National Laboratories for evaluating risk associated with the transportation of radioactive materials. Two sample scenarios were explored relative to the transformation of plutonium pits to MOX fuel. First, the pits would be converted to MOX fuel at a fuel fabrication facility located either at the Pantex Plant or the Savannah River Site (SRS), and then the MOX fuel would be ultimately shipped to a final destination of a commercial power plant, the Palo Verde Generating Station in Arizona. For the scenario of placing the MOX fuel fabrication facility at SRS, pits would need to be shipped from Pantex to SRS and then the MOX fuel would be shipped to Palo Verde. The total number of expected fatalities over a 25 year campaign duration for this scenario would be 1.06, with 0. 1 73 fatalities resulting from latent cancer fatalities due to radiation exposure and 0.89 resulting from traffic accidents. For the placement of the MOX fuel fabrication facility at Pantex, only the MOX fuel would need to be transported from one facility to another, in this case from Pantex to Palo Verde. The total fatalities for this scenario over 25 years would be 0.413, resulting from 5.29 x 10-2 latent cancer fatalities and 0.36 traffic accident fatalities. The maximum exposed individual along any of the three routes would receive 1.0 X 10-5 rem per year or 0.25 mrem over 25 years.

Pair-Trawl Detection of PIT-Tagged Juvenile Salmonids Migrating in the Columbia River Estuary, 2008 Report of Research.  

DOE Green Energy (OSTI)

In 2008, we sampled migrating juvenile Pacific salmonids Oncorhynchus spp. tagged with passive integrated transponder (PIT) tags using a surface pair trawl in the upper Columbia River estuary (rkm 61-83). The cod-end of the trawl was replaced with a cylindrical PIT-tag detection antenna with an 86-cm-diameter fish-passage opening and two detection coils connected in series. The pair trawl was 105 m long with a 91.5-m opening between the wings and a sample depth of 4.9 m. Also during 2008, we finalized the development of a prototype 'matrix' antenna, which was larger than previous antennas by a considerable magnitude. The matrix antenna consisted of 6 coils: a 3-coil front component and a 3-coil rear component, which were separated by 1.5-m of net mesh. The fish-passage opening was 2.5 m wide by 3.0 m tall and was attached to a standard-size pair trawl net. Intermittent sampling with a single crew began on 7 March and targeted yearling Chinook salmon O. tshawytscha and steelhead O. mykiss. Daily sampling using two crews began on 30 April and continued through 14 June; during this period we detected 2.7% of all juvenile salmonids previously detected at Bonneville Dam--a measure of sample efficiency. Sampling with a single crew continued through 20 August and targeted subyearling Chinook salmon. We detected 7,397 yearling Chinook salmon, 2,735 subyearling Chinook salmon, 291 coho salmon O. kisutch, 5,950 steelhead, and 122 sockeye salmon O. nerka in the upper estuary. We deployed the matrix antenna system and the older, cylindrical antenna system (86-cm-diameter fish-passage opening) simultaneously in mid-May 2008 to test matrix detection efficiency. The cylindrical antenna system had been used successfully in 2007 and early 2008. Because distribution of migrating salmonids in the estuary changes rapidly, we felt that a tandem sampling effort between the two systems was the only way to truly evaluate comparative detection efficiency. We deployed both systems within 1 km of each other during a period of high fish densities on 13, 14, and 15 May. Detections of the matrix system surpassed those of the cylindrical system by 53% in 14 h of simultaneous sampling (total detections 716 and 339, respectively). We believe that the higher detection rate observed with the matrix system was due to fewer smolts escaping the trawl entrance and to more smolts readily passing through the larger fish-passage opening. After tandem sampling, we continued exclusive use of the matrix system for the remainder of the 2008 juvenile migration season. Mean survival rates from Lower Granite to Bonneville Dam for yearling Chinook salmon and steelhead were 42% (SE = 3.7%) and 46% (SE = 1.5%), respectively. Over 358,000 PIT-tagged salmonids were transported, and we detected 4,619 of these fish.

EARTHSAWtm IN-SITU CONTAINMENT OF PITS AND TRENCHES  

SciTech Connect

EarthSaw{trademark} is a proposed technology for construction of uniform high quality barriers under and around pits and trenches containing buried radioactive waste without excavating or disturbing the waste. The method works by digging a deep vertical trench around the perimeter of a site, filling that trench with high specific gravity grout sealant, and then cutting a horizontal bottom pathway at the base of the trench with a simple cable saw mechanism.

Expansion of the commercial output of Estonian oil shale mining and processing  

Science Conference Proceedings (OSTI)

Economic and ecological preconditions are considered for the transition from monoproduct oil shale mining to polyproduct Estonian oil shale deposits. Underground water, limestone, and underground heat found in oil shale mines with small reserves can be operated for a long time using chambers left after oil shale extraction. The adjacent fields of the closed mines can be connected to the operations of the mines that are still working. Complex usage of natural resources of Estonian oil shale deposits is made possible owing to the unique features of its geology and technology. Oil shale seam development is carried out at shallow depths (40--70 m) in stable limestones and does not require expensive maintenance. Such natural resources as underground water, carbonate rocks, heat of rock mass, and underground chambers are opened by mining and are ready for utilization. Room-and-pillar mining does not disturb the surface, and worked oil shale and greenery waste heaps do not breach its ecology. Technical decisions and economic evaluation are presented for the complex utilization of natural resources in the boundaries of mine take of the ``Tammiku`` underground mine and the adjacent closed mine N2. Ten countries have already experienced industrial utilization of oil shale in small volumes for many years. Usually oil shale deposits are not notable for complex geology of the strata and are not deeply bedded. Thus complex utilization of quite extensive natural resources of Estonian oil shale deposits is of both scientific and practical interest.

Effects of Inclusions in HSLA Carbon Steel on Pitting Corrosion in CaCl2  

SciTech Connect

Susceptibility of high strength low alloy steel to localized corrosion was studied in 6.7 M CaCl{sub 2} for oil and natural gas drilling applications. Results of the immersion and electrochemical experiments showed that the steel is susceptible to pitting corrosion. Optical microscopy investigations of the polished samples revealed that 10% of the surface area was occupied by defects in the form of pits. The energy dispersive X-ray (EDX) and wavelength dispersive X-ray (WDX) chemical analyses revealed higher concentrations of Mn and S compared to the metal matrix in defected areas. These areas served as the sites for development of corrosion pits during both immersion and electrochemical experiments. The fatigue results of the corroded samples indicate that if the pit was the most significant defect, the fatigue crack initiated and propagated at this site.

Pit disassembly and conversion demonstration environmental assessment and research and development activities  

Science Conference Proceedings (OSTI)

A significant portion of the surplus plutonium is in the form of pits, a nuclear weapons component. Pits are composed of plutonium which is sealed in a metallic shell. These pits would need to be safely disassembled and permanently converted to an unclassified form that would be suitable for long-term disposition and international inspection. To determine the feasibility of an integrated pit disassembly and conversion system, a Pit Disassembly and Conversion Demonstration is proposed to take place at the Los Alamos National Laboratory (LANL). This demonstration would be done in existing buildings and facilities, and would involve the disassembly of up to 250 pits and conversion of the recovered plutonium to plutonium metal ingots and plutonium dioxide. This demonstration also includes the conversion of up to 80 kilograms of clean plutonium metal to plutonium dioxide because, as part of the disposition process, some surplus plutonium metal may be converted to plutonium dioxide in the same facility as the surplus pits. The equipment to be used for the proposed demonstration addressed in this EA would use some parts of the Advanced Recovery and Integrated Extraction System (ARIES) capability, other existing equipment/capacities, plus new equipment that was developed at other sites. In addition, small-scale R and D activities are currently underway as part of the overall surplus plutonium disposition program. These R and D activities are related to pit disassembly and conversion, MOX fuel fabrication, and immobilization (in glass and ceramic forms). They are described in Section 7.0. On May 16, 1997, the Office of Fissile Materials Disposition (MD) notified potentially affected states and tribes that this EA would be prepared in accordance with NEPA. This EA has been prepared to provide sufficient information for DOE to determine whether a Finding of No Significant Impact (FONSI) is warranted or whether an EIS must be prepared.

FIBROUS MONOLITH WEAR RESISTANT COMPONENTS FOR THE MINING INDUSTRY  

Science Conference Proceedings (OSTI)

The work performed on this program was to develop wear resistant, tough FM composite materials with efforts focused on WC-Co based FM systems. The materials were developed for use in mining industry wear applications. Components of interest were drill bit inserts for drilling blast holes. Other component applications investigated included wear plates for a variety of equipment such as pit shovels, wear surfaces for conveyors, milling media for ball milling operations, hydrocyclone cones, grader blades and dozer teeth. Cross-cutting technologies investigated included hot metal extrusion dies, drill bits for circuit board fabrication, cutting tools for cast iron and aluminum machining. An important part of the work was identification of the standard materials used in drilling applications. A materials trade study to determine those metals and ceramics used for mining applications provided guidance for the most important materials to be investigated. WC-Co and diamond combinations were shown to have the most desirable properties. Other considerations such as fabrication technique and the ability to consolidate shifted the focus away from diamond materials and toward WC-Co. Cooperating partners such as Kennametal and Kyocera assisted with supplies, evaluations of material systems, fabricated parts and suggestions for cross-cutting technology applications for FM architectures. Kennametal provided the raw materials (WC-Co and Al-TiCN powders) for the extent of the material evaluations. Kyocera shared their research into various FM systems and provided laboratory testing of fabricated materials. Kyocera also continued research of the FM systems with the intention of developing commercial markets for a variety of applications. The continued development of FM technology by Kyocera is seen as a direct result of the cooperation established under this funding. Kyocera has a specific interest in the commercial development of the FM technology and have licensed it and have paid for the right to develop FM materials for the commercial exploitation. Field testing provided by partners Superior Rock Bit and Brady Mining and Construction provided insight into the performance of the fabricated materials under actual operational conditions. Superior Rock Bit was permitted to evaluate tri-cone roller bits in drilling applications at a mine in the Iron Range of Minnesota. Brady performed evaluation of the roof bit inserts at coal mines in medium hardness strata. The coal mine used for testing was not revealed. Additional field testing of cross-cutting technology, the extrusion of hot metals, at Extruded Metals showed the potential for additional market development. While ACR was able to perform field testing in a number of mines, tunnel boring locations and at a hot metal extrusion house under this effort, limitations of material suppliers reduced our ability to take advantage of the offered facilities at mines in the southern Arizona region. Phelps Dodge mine at Green Valley Arizona provided equipment inserts to modify for evaluation. It was a lack of available standard materials that prevented a field test to evaluate the ACR FM inserts in the application at the Green Valley mine. Efforts to develop an alternate copper electrowinning anode were pursued with additional funding from DOE. Material systems were fabricated and evaluated by research partner Hazen Research. While a drop-in replacement was not identified promising directions for future research were suggested.

Science Conference Proceedings (OSTI)

This design-only conceptual design report (DOCDR) was prepared to support a funding request by the Department of Energy (DOE)-Office of Fissile Material Disposition (OFMD) for engineering design of the Pit Disassembly and Conversion Facility (PDCF) Project No. 99-D-141. The PDCF will be used to disassemble the nation`s inventory of surplus nuclear weapons pits and convert the plutonium recovered from those pits into a form suitable for storage, international inspection, and final disposition. The PDCF is a complex consisting of a hardened building that will contain the plutonium processes in a safe and secure manner, and conventional buildings and structures that will house support personnel, systems, and equipment. The PDCF uses the Advanced Recovery and Integrated Extraction System (ARIES), a low waste, modular pyroprocessing system to convert pits to plutonium oxide. The PDCF project consists of engineering and design, and construction of the buildings and structures, and engineering and design, procurement, installation, testing and start-up of equipment to disassemble pits and convert plutonium in pits to oxide form. The facility is planned to operate for 10 years, averaging 3.5 metric tons (3.86 tons) of plutonium metal per year. On conclusion of operations, the PDCF will be decontaminated and decommissioned.

White phosphorus pits focused feasibility study final July 2007.  

SciTech Connect

The White Phosphorus Burning Pits (WPP) Area of Concern (AOC) is a site of about 5.5 acres (2.2 ha) located in the J-Field Study Area, in the Edgewood Area of Aberdeen Proving Ground (APG), Maryland (Figure 1.1). Considerable information about the WPP exists as a result of efforts to characterize the hazards associated with J-Field. Contamination in the J-Field Study Area was first detected during an environmental survey of the APG Edgewood Area conducted in 1977 and 1978 (Nemeth et al. 1983) by the U.S. Army Toxic and Hazardous Materials Agency (USATHAMA; predecessor to the U.S. Army Environmental Center). As part of a subsequent USATHAMA environmental survey, 11 wells were installed and sampled at J-Field (three of them at the WPP) (Nemeth 1989). Contamination was also detected in 1983 during a munitions disposal survey conducted by Princeton Aqua Science (1984). The Princeton Aqua Science investigation involved installing and sampling nine wells (four at the WPP) and collecting and analyzing surficial and deep composite soil samples (including samples from the WPP area). In 1986, the U.S. Environmental Protection Agency (EPA) issued a Resource Conservation and Recovery Act (RCRA) Permit (MD3-21-002-1355) requiring a post-wide RCRA Facility Assessment (RFA) and a hydrogeologic assessment of J-Field. In 1987, the U.S. Geological Survey (USGS) began a two-phase hydrogeologic assessment in which data were collected to model groundwater flow at J-Field. Soil-gas investigations were conducted, several well clusters were installed (four at the WPP), a groundwater flow model was developed, and groundwater and surface water monitoring programs were established that continue today. The results of the USGS study were published by Hughes (1993).

Los Alamos National Laboratory W76 Pit Tube Lifetime Study  

SciTech Connect

A metallurgical study was requested as part of the Los Alamos National Laboratory (LANL) W76-1 life-extension program (LEP) involving a lifetime analysis of type 304 stainless steel pit tubes subject to repeat bending loads during assembly and disassembly operations at BWXT/Pantex. This initial test phase was completed during the calendar years of 2004-2006 and the report not issued until additional recommended tests could be performed. These tests have not been funded to this date and therefore this report is considered final. Tubes were reportedly fabricated according to Rocky Flats specification P14548 - Seamless Type 304 VIM/VAR Stainless Steel Tubing. Tube diameter was specified as 0.125 inches and wall thickness as 0.028 inches. A heat treat condition is not specified and the hardness range specification can be characteristic of both 1/8 and 1/4 hard conditions. Properties of all tubes tested were within specification. Metallographic analysis could not conclusively determine a specified limit to number of bends allowable. A statistical analysis suggests a range of 5-7 bends with a 99.95% confidence limit. See the 'Statistical Analysis' section of this report. The initial phase of this study involved two separate sets of test specimens. The first group was part of an investigation originating in the ESA-GTS [now Gas Transfer Systems (W-7) Group]. After the bend cycle test parameters were chosen (all three required bends subjected to the same amount of bend cycles) and the tubes bent, the investigation was transferred to Terri Abeln (Metallurgical Science and Engineering) for analysis. Subsequently, another limited quantity of tubes became available for testing and were cycled with the same bending fixture, but with different test parameters determined by T. Abeln.

Hot dry rock heat mining: An alternative energy progress report  

DOE Green Energy (OSTI)

Mining Heat from the hot dry rock (HDR) resource that lies beneath the earth's crust may provide an almost inexhaustible supply of energy for mankind with minimal environmental effects. In the heat mining process, water is pumped down an injection well into a mass of hydraulically fractured hot rock. As the water flows under high pressure through the opened rock joints, it becomes heated by the rock. It is returned to the surface through a production well (or wells) located some distance from the injector where its thermal energy is recovered by a heat exchanger. The same water is then recirculated through the system to extract more thermal energy. In this closed-loop process, nothing but heat is released to the environment during normal operation. The technical feasibility of HDR heat mining already has been proven by field testing. A long-term flow test is scheduled to begin in 1991 at the world's largest HDR heat mine in New Mexico, USA, to demonstrate that energy can be produced from HDR on a continuous basis over an extended time period. Significant HDR programs are also underway in several other countries. The paper describes the HDR resource, the heat mining concept, environmental characteristics, economics, developments at Los Alamos to date, and HDR development outside the US. 15 refs., 5 figs., 2 tabs.

Web Mining – the Ontology Approach  

E-Print Network (OSTI)

The World Wide Web today provides users access to extremely large number of Web sites many of which contain information of education and commercial values. Due to the unstructured and semi-structured nature of Web pages and the design idiosyncrasy of Web sites, it is a challenging task to develop digital libraries for organizing and managing digital content from the Web. Web mining research, in its last 10 years, has on the other hand made significant progress in categorizing and extracting content from the Web. In this paper, we represent ontology as a set of concepts and their inter-relationships relevant to some knowledge domain. The knowledge provided by ontology is extremely useful in defining the structure and scope for mining Web content. We will therefore review Web mining and describe the ontology approach to Web mining. The application of these Web mining techniques to digital library systems will also be discussed.

Measuring mine roof bolt strains  

DOE Patents (OSTI)

A mine roof bolt and a method of measuring the strain in mine roof bolts of this type are disclosed. According to the method, a flat portion on the head of the mine roof bolt is first machined. Next, a hole is drilled radially through the bolt at a predetermined distance from the bolt head. After installation of the mine roof bolt and loading, the strain of the mine roof bolt is measured by generating an ultrasonic pulse at the flat portion. The time of travel of the ultrasonic pulse reflected from the hole is measured. This time of travel is a function of the distance from the flat portion to the hole and increases as the bolt is loaded. Consequently, the time measurement is correlated to the strain in the bolt. Compensation for various factors affecting the travel time are also provided.

Inductive learning as a fusion engine for mine detection  

SciTech Connect

Semiotics is defined by some researchers as {open_quotes}the study of the appearance (visual or otherwise) meaning, and use of symbols and symbol systems.{close_quotes} Semiotic fusion of data from multiple sensory sources is a potential solution to the problem of landmine detection. This turns out to be significant, because notwithstanding the diversity of sensor technologies being used to attack the problem, there is no single effective landmine sensor technology. The only practical, general-purpose mine detector presently available is the trained dog. Most research into mine-detection technology seeds to emulate the dog`s seemingly uncanny abilities. An ideal data-fusion system would mimic animal reaction, with the brain`s perceptive power melding multiple sensory cues into an awareness of the size and location of a mine. Furthermore, the fusion process should be adaptive, with the skill at combining cues into awareness improving with experience. Electronic data-fusion systems reported in the countermine literature use conventional vector-based pattern recognition methods. Although neural nets are popular, they have never satisfactorily met the challenge. Despite years of investigation, nobody has ever found a vector space representation that reliably characterizes mine identity. This strongly suggests that the features have not been found because researchers have been looking for the wrong characteristics. It is worth considering that dogs probably do not represent data as mathematical number lists, but they almost certainly represent data via semiotic structures.

Closure Report for Corrective Action Unit 357: Mud Pits and Waste Dump, Nevada Test Site, Nevada, Rev. No.: 0  

SciTech Connect

This Closure Report (CR) presents information supporting closure of Corrective Action Unit (CAU) 357: Mud Pits and Waste Dump, Nevada Test Site (NTS), Nevada. The CR complies with the requirements of the Federal Facility Agreement and Consent Order (FFACO) that was agreed to by the State of Nevada, U.S. Department of Energy (DOE), and the U.S. Department of Defense (FFACO, 1996). Corrective Action Unit 357 is comprised of 14 Corrective Action Sites (CASs) located in Areas 1, 4, 7, 8, 10, and 25 of the NTS (Figure 1-1). The NTS is located approximately 65 miles (mi) northwest of Las Vegas, Nevada. Corrective Action Unit 357 consists of 11 CASs that are mud pits located in Areas 7, 8, and 10. The mud pits were associated with drilling activities conducted on the NTS in support of the underground nuclear weapons testing. The remaining three CASs are boxes and pipes associated with Building 1-31.2el, lead bricks, and a waste dump. These CAS are located in Areas 1, 4, and 25, respectively. The following CASs are shown on Figure 1-1: CAS 07-09-02, Mud Pit; CAS 07-09-03, Mud Pit; CAS 07-09-04, Mud Pit; CAS 07-09-05, Mud Pit; CAS 08-09-01, Mud Pit; CAS 08-09-02, Mud Pit; CAS 08-09-03, Mud Pit; CAS 10-09-02, Mud Pit; CAS 10-09-04, Mud Pit; CAS 10-09-05, Mud Pit; CAS 10-09-06, Mud Pit, Stains, Material; CAS 01-99-01, Boxes, Pipes; CAS 04-26-03, Lead Bricks; and CAS 25-15-01, Waste Dump. The purpose of the corrective action activities was to obtain analytical data that supports the closure of CAU 357. Environmental samples were collected during the investigation to determine whether contaminants exist and if detected, their extent. The investigation and sampling strategy was designed to target locations and media most likely to be contaminated (biased sampling). A general site conceptual model was developed for each CAS to support and guide the investigation as outlined in the Streamlined Approach for Environmental Restoration (SAFER) Plan (NNSA/NSO, 2003b). This CR summarizes the results of corrective action activities, provides the data confirming the selection of corrective actions, and provides documentation of the completed closure activities conducted in accordance with the SAFER Plan (NNSA/NSO, 2003b). A brief description of the CAU and associated CASs is provided in the following section. A more detailed history of each CAS is provided in the SAFER Plan for CAU 357 (NNSA/NSO, 2003b).

The AL-R8 SI: The next generation staging container for plutonium pits at the USDOE Pantex Plant  

SciTech Connect

The AL-R8 SI (sealed insert) is the next generation staging container for plutonium pits at the US DOE Pantex Plant. The sealed insert is a stainless steel container that will be placed inside a modified AL-R8 container to stage pits. A pit is a hollow sphere of plutonium metal which is the primary fissionable material in nuclear weapons (warheads and bombs). It is hermetically sealed by a cladding material, which is usually stainless steel. Personnel exposures to ionizing radiation from the pits in storage are expected to decrease due to the attenuation provided by the new SI. All personnel exposures to ionizing radiation at Pantex Plant are As Low As Reasonably Achievable (ALARA). Pantex Plant secures the common defense and national security of the US by safely staging plutonium pits in a manner that protests the health and safety of employees, the public, and the environment.

This Interim Construction Quality Assurance (CQA) Report is for the 92-Acre Evapotranspiration Cover, Area 5 Waste Management Division (WMD) Retired Mixed Waste Pits, Nevada National Security Site, Nevada for the period of January 20, 2011 to May 12, 2011. Construction was approved by the Nevada Division of Environmental Protection (NDEP) under the Approval of Corrective Action Decision Document/Corrective Action Plan (CADD/CAP) for Corrective Action Unit (CAU) 111: Area 5 WMD Retired Mixed Waste Pits, Nevada National Security Site, Nevada, on January 6, 2011, pursuant to Subpart XII.8a of the Federal Facility Agreement and Consent Order. The project is located in Area 5 of the Radioactive Waste Management Complex (RWMC) at the Nevada National Security Site (NNSS), formerly known as the Nevada Test Site, located in southern Nevada, approximately 65 miles northwest of Las Vegas, Nevada, in Nye County. The project site, in Area 5, is located in a topographically closed basin approximately 14 additional miles north of Mercury Nevada, in the north-central part of Frenchman Flat. The Area 5 RWMS uses engineered shallow-land burial cells to dispose of packaged waste. The 92-Acre Area encompasses the southern portion of the Area 5 RWMS, which has been designated for the first final closure operations. This area contains 13 Greater Confinement Disposal (GCD) boreholes, 16 narrow trenches, and 9 broader pits. With the exception of two active pits (P03 and P06), all trenches and pits in the 92-Acre Area had operational covers approximately 2.4 meters thick, at a minimum, in most areas when this project began. The units within the 92-Acre Area are grouped into the following six informal categories based on physical location, waste types and regulatory requirements: (1) Pit 3 Mixed Waste Disposal Unit (MWDU); (2) Corrective Action Unit (CAU) 111; (3) CAU 207; (4) Low-level waste disposal units; (5) Asbestiform low-level waste disposal units; and (6) One transuranic (TRU) waste trench.

Acid Pit Stabilization Project (Volume 1 - Cold Testing) and (Volume 2 - Hot Testing)  

SciTech Connect

During the summer and fall of Fiscal Year 1997, a Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Treatability Study was performed at the Idaho National Engineering and Environmental Laboratory. The study involved subsurface stabilization of a mixed waste contaminated soil site called the Acid Pit. This study represents the culmination of a successful technology development effort that spanned Fiscal Years 1994-1996. Research and development of the in situ grout stabilization technique was conducted. Hardware and implementation techniques are currently documented in a patent pending with the United States Patent and Trademark Office. The stabilization technique involved using jet grouting of an innovative grouting material to form a monolith out of the contamination zone. The monolith simultaneously provides a barrier to further contaminant migration and closes voids in the soil structure against further subsidence. This is accomplished by chemical incorporation of contaminants into less soluble species and achieving a general reduction in hydraulic conductivity within the monolith. The grout used for this study was TECT-HG, a relatively dense iron oxide-based cementitious grout. The treatability study involved cold testing followed by in situ stabilization of the Acid Pit. Volume 1 of this report discusses cold testing, performed as part of a ''Management Readiness Assessment'' in preparation for going hot. Volume 2 discusses the results of the hot Acid Pit Stabilization phase of this project. Drilling equipment was specifically rigged to reduce the spread of contamination, and all grouting was performed under a concrete block containing void space to absorb any grout returns. Data evaluation included examination of implementability of the grouting process and an evaluation of the contaminant spread during grouting. Following curing of the stabilized pit, cores were obtained and evaluated for toxicity characteristic leach ing procedure protocol for the main contaminant of concern, which was mercury. In addition, the cores were evaluated for the extent of mixing of the injected grout and the contaminated soil. A postgrouting geophysical evaluation of the grouted pit is presented.

Surface mine blasting - make it work for you  

SciTech Connect

Understanding the mechanics of blasting and its relationship to the mining operation as a whole underlie the most successful blasting programs. The apparent burden and spacing measured from the drill pattern may not necessarily be the effective burden and spacing during the blast. The detonation sequence of the holes can cause these measurements to change. The true spacing-to-burden relationship, shot timing, and explosive used will all affect overburden movement and breakage. Opinions vary regarding the proper selection of these variables for specific purposes. Cast blasting has received a renewed interest in the past few years, especially in surface coal mines. Improved fragmentation is often an extra benefit of casting. The principles of cast blasting may be used to open a key along the new highwall, improve productivity of truck operati, ons, and help directional spoil movement in special applications. 6 references4 figures

Large mining blasts from the Kursk Mining Region, Russia  

SciTech Connect

Monitoring the Comprehensive Nuclear Test Ban Treaty (CTBT) by seismic means will require identification of seismic sources at magnitude levels where industrial explosions (primarily, mining blasts) may comprise a significant fraction of the total number of events recorded, and may for some countries dominate the seismicity. Thus, data on blasting practice have both political significance for the negotiation of treaties involving seismic monitoring of nuclear tests, and operational applications in terms of establishing monitoring and inspection needs on a mine-by-mine basis. While it is generally accepted that mining explosions contribute to seismicity at lower seismic magnitudes (less than about magnitude 3.5), the rate of mining seismicity as a function of seismic magnitude is unknown for most countries outside the U.S. This results in a large uncertainty when estimating the task of discriminating nuclear explosions from chemical explosions and earthquakes, by seismic means, under a comprehensive nuclear test ban. This uncertainty directly affects estimates of seismic network enhancements required to achieve treaty verification requirements at magnitudes less than about 3.5. 24 refs., 64 figs., 11 tabs.

Dewatering of Ambrosia Lake Mines  

SciTech Connect

The paper discusses the design of an aquifer depressurisation system using wells at Mt. Taylor Mine, Ambrosia Lake, New Mexico. The concepts discussed should be valid for any shaft of mine in a sandstone aquifer with predominantly matrix permeability. The system uses a number of wells surrounding the mine shaft to reduce the aquifer pressure in the vicinity of the shaft. The effect of various parameters such as number of wells, wellbore diameter, time and well location are considered. It is concluded that, with a properly designed system, the aquifer pressure and water inflow rate to the shaft may be reduced to less than 15% of their potential values in the absence of wells.

Often, these terms are considered equivalent and/or mutually implicated: “open source is the only way to enforce and exploit open standards”. This position is misleading, as it increases the confusion about this complex and extremely critical topic. The paper clarifies the basic terms and concepts. This is instrumental to suggest a number of actions and practices aiming at promoting and defending openness in modern ICT products and services.

As the Goose Full Flow design progressed and the project started to move towards construction, issues within contracting occurred and the project was put on delay for 1 year. Starting in mid December of 2008, Harcon Inc. was awarded the contract and construction of the new Goose Full Flow PIT-tag detection system began. The purpose of this document is to summarize the installation of the Little Goose Full Flow project from start to finish and to highlight the notable successes and challenges that the installation presented along with the final results and current status.

Adult Salmonid PIT-TAG Returns to Columbia River`s Lower Granite Dam.  

DOE Green Energy (OSTI)

The results of an analysis of the returns of PIT-tagged Snake River spring chinook and steelhead detected at Lower Granite Dam are summarized. Included is theoretical work on statistical power calculations for tests of return rates. The phrase return rate will be taken to mean return and detection rate. Knowledge that a fish has returned depends upon it being detected at Lower Granite Dam. Some returns are unaccounted for because they go through the navigation lock or manage to go through the adult bypass undetected. (1) Adult PIT tag recoveries to date are informative at least from a qualitative perspective. (2) The tagging levels by geographic region, rearing type, and, for chinook, life history stage have varied considerably since PIT tagging began on the Columbia River system. Early tagging studies were directed at Juvenile problems rather than adult return rates. As a result, comparisons in adult return rates between years, regions, etc., are more difficult. Global conclusions about the effect of potential treatments and/or natural factors, such as region of origin, on adult return rates are difficult to make until a more balanced. more consistent tagging study is implemented. (3) Along the same lines, tagging levels will need to be increased considerably if experiments are to be conducted to determine factors that affect return rates. E.g., approximately 46,000 fish in both the control and the treatment groups need to be PIT-tagged to detect a statistically significant difference with 80% probability. (4) Analysis of the available data suggests that life stage (parr or smolt), rearing type (hatchery or wild), and geographic location all affect the return rates for spring chinook. The data are limited, however. (5) Return rates for Snake River steelhead are roughly an order of magnitude greater than Snake River spring chinook return rates.

An Assessment of Freeze Brand and PIT Tag Recovery Data at McNary Dam, 1987 Annual Report.  

DOE Green Energy (OSTI)

This study evaluated mark recovery data from PIT-tagged and freeze-branded fish recovered at McNary Dam in 1987. Hatchery and river-run populations of yearling chinook salmon (Oncorhynchus tshawytscha), sockeye salmon (O. nerka) and steelhead (O. mykiss) were used in this investigation. Paired groups of PIT-tagged and freeze-branded juvenile salmonids were released upstream from McNary Dam and subsequently recaptured at that site. PIT tags were recovered in significantly higher proportions than freeze brands regardless of species of stock. Furthermore, for chinook and sockeye salmon, PIT tag recovery data exhibited less variability. Reasons for the discrepant intermark recovery rates are discussed. 10 refs., 27 figs., 23 tabs.

Corner-cutting mining assembly  

DOE Patents (OSTI)

This invention resulted from a contract with the United States Department of Energy and relates to a mining tool. More particularly, the invention relates to an assembly capable of drilling a hole having a square cross-sectional shape with radiused corners. In mining operations in which conventional auger-type drills are used to form a series of parallel, cylindrical holes in a coal seam, a large amount of coal remains in place in the seam because the shape of the holes leaves thick webs between the holes. A higher percentage of coal can be mined from a seam by a means capable of drilling holes having a substantially square cross section. It is an object of this invention to provide an improved mining apparatus by means of which the amount of coal recovered from a seam deposit can be increased. Another object of the invention is to provide a drilling assembly which cuts corners in a hole having a circular cross section. These objects and other advantages are attained by a preferred embodiment of the invention.

Mines in the Four Corners anticipate growth  

Science Conference Proceedings (OSTI)

Productive mines in the southwest deplete reserves, while the government drags its heels on new power projects. Production in Arizona and New Mexico has fallen 18% over the last four years to 34.1 million tons. With Chevron Mining's McKinley mine rapidly depleting its reserves the industry will continue to contract. In the last three years at least three large mines in the Four Corners have terminated operations. Three others remain captive operations: BHP Billiton's San Juan Underground and Navajo Surface operations and Peabody Energy's Kayenta surface mine. In 2006 the Black Mesa mine stopped producing coal. These four mines are isolated from the national railways. Peabody's new El Segundo surface mine near Grants, NM is increasing production. If the planned $3 billion Desert Rock coal-fired power plant is built this will present a new market for the Navajo mine. The article gives details about the state of the aforementioned mines and of the new King II coal mine on the northern periphery of the San Juan basin and discusses the state of plans for the Desert Rock Energy Project. 5 photos.

Mine closures yield fields of green  

SciTech Connect

The cleanup and reclamation of North America's defunct mines or those set for closure will be extremely costly, estimated to be over one trillion dollars within the next ten to twenty years. In Canada, mines are controlled by the provinces and British Columbia began reclamation of major coal mines and hard rock metal mines in 1969. Other provinces have followed suit and in 1991, Ontario ruled that new and existing mines and advanced exploration projects must be designed for closuer. Many US states are enacting similar laws and the EPA plans to require mines to submit closure plans with their permit applications. Cleanup includes the sale of usable equipment, salvage of the rest, dismantling buildings, treatment and disposal of process chemicals, hazardous materials and tainted soils as well as recontouring and revegetation of the sites. Currently, at Elliot Lake in Canada, three of Canada's largest underground uranium mines are undergoing the process of closure.

Comparative Performance of Acoustic-tagged and PIT-tagged Juvenile Salmonids  

DOE Green Energy (OSTI)

Numerous research tools and technologies are currently being used to evaluate fish passage and survival to determine the impacts of the Federal Columbia River Power System (FCRPS) on endangered and threatened juvenile salmonids, including PIT tags, balloon tags, hydroacoustic evaluations, radio telemetry, and acoustic telemetry. Each has advantages and disadvantages, but options are restricted in some situations because of limited capabilities of a specific technology, lack of detection capability downstream, or availability of adequate numbers of fish. However, there remains concern about the comparative effects of the tag or the tagging procedure on fish performance. The recently developed Juvenile Salmonid Acoustic Telemetry System (JSATS) acoustic transmitter is the smallest active acoustic tag currently available. The goal of this study was to determine whether fish tagged with the JSATS acoustic-telemetry tag can provide unbiased estimates of passage behavior and survival within the performance life of the tag. We conducted both field and laboratory studies to assess tag effects. For the field evaluation we released a total of 996 acoustic-tagged fish in conjunction with 21,026 PIT-tagged fish into the tailrace of Lower Granite Dam on 6 and 13 May. Travel times between release and downstream dams were not significantly different for the majority of the reaches between acoustic-tagged and PIT-tagged fish. In addition to the field evaluation, a series of laboratory experiments were conducted to determine if growth and survival of juvenile Chinook salmon surgically implanted with acoustic transmitters is different than untagged or PIT tagged juvenile Chinook salmon. Only yearling fish with integrated and non-integrated transmitters experienced mortalities, and these were low (<4.5%). Mortality among sub-yearling control and PIT-tag treatments ranged up to 7.7% while integrated and non-integrated treatments had slightly higher rates (up to 8.3% and 7.9% respectively). No acoustic transmitters were shed by yearling fish during the course of the 90 day study. Up to 7.8% of subyearling fish expelled transmitters. Tags were expelled from 5 to 63 days post-surgery. The average time to expulsion was 27 days; few fish expelled transmitters within 14 days of implantation or less. Histological results suggest that inflammation associated with implantation of an acoustic transmitter can produce fibrous tissue which can invade and possibly damage internal organs soon after implantation. Reactions severe enough to damage organs however, were limited to only ~20% of subyearling Chinook salmon, all of which were under 101mm and 12g at tagging. The infiltration of the fibrous tissue into organs was observed most often in fish held for 21 days and appeared to decrease in subsequent holding times.

Survey of Climate Data Mining  

E-Print Network (OSTI)

Global climate change has been a discussion topic for years, finally culminating as a significant problem and a national defense issue according to the 2010 Quadrennial Defense Review. From weather to ecological data, the planet is continuously being monitored by researchers collecting spatio-temporal climate data. With the immense amount of data collected, the challenge is making sense of the data by building models and studying the climatic events that deviate and correlate to the models. Data mining is now being used for this research and has four related problems: preprocessing data, applying data mining techniques to build models and outlier/anomaly detection, evaluation techniques and methods, and data visualization. This survey paper will present a broad survey of these issues by first discussing preprocessing techniques to remove variation and other data quality issues, including a discussion on the two types of outliers: undesirable outliers and outliers that represent interesting climate events. Next this paper will discuss common data mining techniques for building models, including association analysis, clustering, and ICA, and discovering interesting outlier/anomalies using techniques including classification, clustering, and wavelet analysis. Third, evaluation techniques will be covered through descriptions and examples. Finally, issues and techniques for climate data visualization will be discussed including

Human Health and Ecological Risk Assessment Work Plan Mud Pit Release Sites, Amchitka Island, Alaska  

SciTech Connect

This Work Plan describes the approach that will be used to conduct human health and ecological risk assessments for Amchitka Island, Alaska, which was utilized as an underground nuclear test site between 1965 and 1971. During this period, the U.S. Atomic Energy Commission (now the U.S. Department of Energy) conducted two nuclear tests (known as Long Shot and Milrow) and assisted the U.S. Department of Defense with a third test (known as Cannikin). Amchitka Island is approximately 42 miles long and located 1,340 miles west-southwest of Anchorage, Alaska, in the western end of the Aleutian Island archipelago in a group of islands known as the Rat Islands. Historically including deep drilling operations required large volumes of drilling mud, a considerable amount of which was left on the island in exposed mud pits after testing was completed. Therefore, there is a need for drilling mud pit remediation and risk assessment of historical mud pit releases. The scope of this work plan is to document the environmental objectives and the proposed technical site investigation strategies that will be utilized for the site characterization of the constituents in soil, surface water, and sediment at these former testing sites. Its goal is the collection of data in sufficient quantity and quality to determine current site conditions, support a risk assessment for the site surfaces, and evaluate what further remedial action is required to achieve permanent closure of these three sites that will protect both human health and the environment. Suspected compounds of potential ecological concern for investigative analysis at these sites include diesel-range organics, polyaromatic hydrocarbons, polychlorinated biphenyls, volatile organic compounds, and chromium. The results of these characterizations and risk assessments will be used to evaluate corrective action alternatives to include no further action, the implementation of institutional controls, capping on site, or off-sit e disposal of contaminated waste. The results of this evaluation will be presented in a subsequent corrective action decision document.

Design and Analysis of Salmonid Tagging Studies in the Columbia Basin, Volume XVI; Alternative Designs for Future Adult PIT-Tag Detection Studies, 2000 Technical Report.  

DOE Green Energy (OSTI)

In the advent of the installation of a PIT-tag interrogation system in the Cascades Island fish ladder at Bonneville Dam (BON), and other CRB dams, this overview describes in general terms what can and cannot be estimated under seven different scenarios of adult PIT-tag detection capabilities in the CRB. Moreover, this overview attempted to identify minimal adult PIT-tag detection configurations required by the ten threatened Columbia River Basin (CRB) chinook and steelhead ESUs. A minimal adult PIT-tag detection configuration will require the installation of adult PIT-tag detection facilities at Bonneville Dam and another dam above BON. Thus, the Snake River spring/summer and fall chinook salmon, and the Snake River steelhead will require a minimum of three dams with adult PIT-tag detection capabilities to guarantee estimates of ''ocean survival'' and at least of one independent, in-river returning adult survival (e.g., adult PIT-tag detection facilities at BON and LGR dams and at any other intermediary dam such as IHR). The Upper Columbia River spring chinook salmon and steelhead will also require a minimum of three dams with adult PIT-tag detection capabilities: BON and two other dams on the BON-WEL reach. The current CRB dam system configuration and BPA's and COE's commitment to install adult PIT-tag detectors only in major CRB projects will not allow the estimation of an ''ocean survival'' and of any in-river adult survival for the Lower Columbia River chinook salmon and steelhead. The Middle Columbia River steelhead ESU will require a minimum of two dams with adult PIT-tag detection capabilities: BON and another upstream dam on the BON-McN reach. Finally, in spite of their importance in terms of releases, PIT-tag survival studies for the Upper Willamette chinook and Upper Willamette steelhead ESUs cannot be perform with the current CRB dam system configuration and PIT-tag detection capabilities.

Comparative Performance of Acoustic-tagged and PIT-tagged Juvenile Salmonids  

Science Conference Proceedings (OSTI)

Numerous research tools and technologies are currently being used to evaluate fish passage and survival to determine the impacts of the Federal Columbia River Power System (FCRPS) on endangered and threatened juvenile salmonids, including PIT tags, balloon tags, hydroacoustic evaluations, radio telemetry, and acoustic telemetry. Each has advantages and disadvantages, but options are restricted in some situations because of limited capabilities of a specific technology, lack of detection capability downstream, or availability of adequate numbers of fish. However, there remains concern about the comparative effects of the tag or the tagging procedure on fish performance. The recently developed Juvenile Salmonid Acoustic Telemetry System (JSATS) acoustic transmitter is the smallest active acoustic tag currently available. The goal of this study was to determine whether fish tagged with the JSATS acoustic-telemetry tag can provide unbiased estimates of passage behavior and survival within the performance life of the tag. We conducted both field and laboratory studies to assess tag effects. For the field evaluation we released a total of 996 acoustic-tagged fish in conjunction with 21,026 PIT-tagged fish into the tailrace of Lower Granite Dam on 6 and 13 May. Travel times between release and downstream dams were not significantly different for the majority of the reaches between acoustic-tagged and PIT-tagged fish. In addition to the field evaluation, a series of laboratory experiments were conducted to determine if growth and survival of juvenile Chinook salmon surgically implanted with acoustic transmitters is different than untagged or PIT tagged juvenile Chinook salmon. Only yearling fish with integrated and non-integrated transmitters experienced mortalities, and these were low (tag treatments ranged up to 7.7% while integrated and non-integrated treatments had slightly higher rates (up to 8.3% and 7.9% respectively). No acoustic transmitters were shed by yearling fish during the course of the 90 day study. Up to 7.8% of subyearling fish expelled transmitters. Tags were expelled from 5 to 63 days post-surgery. The average time to expulsion was 27 days; few fish expelled transmitters within 14 days of implantation or less.

Reactions severe enough to damage organs however, were limited to only ~20% of subyearling Chinook salmon, all of which were under 101mm and 12g at tagging. The infiltration of the fibrous tissue into organs was observed most often in fish held for 21 days and appeared to decrease in subsequent holding times.

RADIOACTIVE HIGH LEVEL WASTE TANK PITTING PREDICTIONS: AN INVESTIGATION INTO CRITICAL SOLUTION CONCENTRATIONS  

Science Conference Proceedings (OSTI)

A series of cyclic potentiodynamic polarization tests was performed on samples of ASTM A537 carbon steel in support of a probability-based approach to evaluate the effect of chloride and sulfate on corrosion the steel?s susceptibility to pitting corrosion. Testing solutions were chosen to systemically evaluate the influence of the secondary aggressive species, chloride, and sulfate, in the nitrate based, high-level wastes. The results suggest that evaluating the combined effect of all aggressive species, nitrate, chloride, and sulfate, provides a consistent response for determining corrosion susceptibility. The results of this work emphasize the importance for not only nitrate concentration limits, but also chloride and sulfate concentration limits.

Pitting corrosion behavior of 316L stainless steel in the media of sulphate-reducing and iron-oxidizing bacteria  

SciTech Connect

Pitting corrosion behavior of 316L SS was investigated in the presence of aerobic and anaerobic bacteria isolated from cooling water system in oil refinery using polarization measurement, electrochemical impedance spectroscopy, scanning electron microscopy examinations and energy dispersive spectrum analysis. The results show the corrosion potential (E{sub corr}), pitting potential (E{sub pit}) and polarization resistance (R{sub P}) of 316L SS had a distinct decrease in the presence of bacteria, in comparison with those observed in the sterile medium for the same exposure time interval. Micrometer-scale pitting was observed on the 316L SS surface in the presence of bacteria. The combination of SRB and IOB demonstrated higher corrosion rates than SRB or IOB alone. The synergy of 0.01 M NaCl + SRB + IOB yielded the highest corrosion rate. The synergies between the metal surface, abiotic corrosion products, chloride anion, and bacterial cells and their metabolic products increased the corrosion damage degree of the passive film and accelerated pitting propagation.

In situ vitrification demonstration at Pit 1, Oak Ridge National Laboratory. Volume 1: Results of treatability study  

Science Conference Proceedings (OSTI)

A treatability study was initiated in October 1993 to apply in situ vitrification (ISV) to at least two segments of Oak Ridge National Laboratory (ORNL) seepage Pit 1 by the end of fiscal year (FY) 1995. This treatability study was later extended to include all of Pit 1 and was performed to support a possible Interim Record of Decision or removal action for closure of one or more of the seepage pits and trenches beginning as early as FY 1997. This treatability study was carried out to establish the field-scale technical performance of ISV for (1) attaining the required depth, nominally 15 ft, to incorporate source contamination within and beneath the pits; (2) demonstrating field capability for the overlap of melt settings which will be necessary to achieve fused, melted segments of the source contamination; (3) demonstrating off-gas handling technology for accommodating and minimizing the volatilization of {sup 137}Cs; (4) demonstrating adequate site characterization techniques to predict ISV melting kinetics, processing temperatures, and product durability; and (5) promoting public acceptance of ISV technology by demonstrating its safety, implementability, site impacts, and air emissions and by coordinating the treatability study within the regulatory closure process. In April 1996 an expulsion of an estimated 10% of the 196 Mg (216 tons) melt body occurred resulting in significant damage to ISV equipment and, ultimately, led to an indefinite suspension of further ISV operations at Pit 1. This report summarizes the technical accomplishments and status of the project in fulfilling these objectives through September 1997.

Science Conference Proceedings (OSTI)

The Mercury Fire Training Pit is a former fire training area located in Area 23 of the Nevada Test Site (NTS). The Mercury Fire Training Pit was used from approximately 1965 to the early 1990s to train fire-fighting personnel at the NTS, and encompasses an area approximately 107 meters (m) (350 feet [ft]) by 137 m (450 ft). The Mercury Fire Training Pit formerly included a bermed burn pit with four small burn tanks, four large above ground storage tanks an overturned bus, a telephone pole storage area, and areas for burning sheds, pallets, and cables. Closure activities will include excavation of the impacted soil in the aboveground storage tank and burn pit areas to a depth of 1.5 m (5 ft), and excavation of the impacted surface soil downgradient of the former ASTs and burnpit areas to a depth of 0.3 m (1 ft). Excavated soil will be disposed in the Area 6 Hydrocarbon Landfill at the NTS.

Ground penetrating radar technique to locate coal mining related features: case studies in Texas  

E-Print Network (OSTI)

The goal of this research project is to identify the efficacy of the ground penetrating radar (GPR) technique in locating underground coal mine related subsidence features at Malakoff and Bastrop, Texas. The work at Malakoff has been done in collaboration with the Railroad Commission of Texas (RRC). RRC has been carrying out reclamation of abandoned underground coal mines at Malakoff since the early 1990Â?s. The history of the specific mining operations (at Malakoff and Bastrop) that took place in the early 1900Â?s has been difficult to ascertain; therefore, the use of a geophysical techniques like ground penetrating radar to identify hidden voids and potential subsidence features is vital for future reclamation process. Some of the underground mine workings at the field site have collapsed over time affecting the topography by creating sinkholes. GPR data, employing 25 MHz, 50 MHz and 100 MHz frequency antennae, have been collected in common offset patterns and azimuthal pattern. GPR data indicate the mine tunnels possibly connecting existing sinkholes by radargram hyperbolae that correspond with mine openings observed visually or during reclamation. This study also denotes the importance of understanding the variable physical properties of the stratigraphy, which could lead to false alarms by misinterpretation of the radar signals. Natural and man-made above-ground structures cause obstructions in data collection, and hence an optimal design is required for each survey. RRC successfully ground-truthed the data during its reclamation process. In turn, the acquired geophysical data helped to guide the reclamation. At Bastrop, GPR data along with historical documentation led to the conclusion that coal mining did exist in this region but is not a major concern to the immediate stability and safety of the field site. It can be concluded from both the studies that the GPR technique identifies anomalous shafts/tunnels possibly connecting potential failure.

Special Analysis: Disposal Plan for Pit 38 at Technical Area 54, Area G  

Science Conference Proceedings (OSTI)

Los Alamos National Laboratory (LANL) generates radioactive waste as a result of various activities. Operational waste is generated from a wide variety of research and development activities including nuclear weapons development, energy production, and medical research; environmental restoration (ER), and decontamination and decommissioning (D&D) waste is generated as contaminated sites and facilities at LANL undergo cleanup or remediation. The majority of this waste is low-level radioactive waste (LLW) and is disposed of at the Technical Area 54 (TA-54), Area G disposal facility. U.S. Department of Energy (DOE) Order 435.1 (DOE, 2001) requires that radioactive waste be managed in a manner that protects public health and safety, and the environment. To comply with this order, DOE field sites must prepare site-specific radiological performance assessments for LLW disposal facilities that accept waste after September 26, 1988. Furthermore, sites are required to conduct composite analyses that account for the cumulative impacts of all waste that has been (or will be) disposed of at the facilities and other sources of radioactive material that may interact with the facilities. Revision 4 of the Area G performance assessment and composite analysis was issued in 2008 (LANL, 2008). These analyses estimate rates of radionuclide release from the waste disposed of at the facility, simulate the movement of radionuclides through the environment, and project potential radiation doses to humans for several on- and off-site exposure scenarios. The assessments are based on existing site and disposal facility data, and on assumptions about future rates and methods of waste disposal. The Area G disposal facility consists of Material Disposal Area (MDA) G and the Zone 4 expansion area. To date, disposal operations have been confined to MDA G and are scheduled to continue in that region until MDA G undergoes final closure at the end of 2013. Given its impending closure, efforts have been made to utilize the remaining disposal capacity within MDA G to the greatest extent possible. One approach for doing this has been to dispose of low-activity waste from cleanup operations at LANL in the headspace of selected disposal pits. Waste acceptance criteria (WAC) for the material placed in the headspace of pits 15, 37, and 38 have been developed (LANL, 2010) and the impacts of placing waste in the headspace of these units has been evaluated (LANL, 2012a). The efforts to maximize disposal efficiency have taken on renewed importance because of the disposal demands placed on MDA G by the large volumes of waste that are being generated at LANL by cleanup efforts. For example, large quantities of waste were recently generated by the retrieval of waste formerly disposed of at TA-21, MDA B. A portion of this material has been disposed of in the headspace of pit 38 in compliance with the WAC developed for that disposal strategy; a large amount of waste has also been sent to off-site facilities for disposal. Nevertheless, large quantities of MDA B waste remain that require disposal. An extension of pit 38 was proposed to provide the disposal capacity that will be needed to dispose of institutional waste and MDA B waste through 2013. A special analysis was prepared to evaluate the impacts of the pit extension (LANL, 2012b). The analysis concluded that the disposal unit could be extended with modest increases in the exposures projected for the Area G performance assessment and composite analysis, as long as limits were placed on the radionuclide concentrations in the waste that is placed in the headspace of the pit. Based, in part, on the results of the special analysis, the extension of pit 38 was approved and excavation of the additional disposal capacity was started in May 2012. The special analysis presented here uses performance modeling to identify a disposal plan for the placement of waste in pit 38. The modeling uses a refined design of the disposal unit and updated radionuclide inventories to identify a disposal configuration that promotes efficie

Evaluation of Fish Movements, Migration Patterns, and Population Abundance with Streamwidth PIT Tag Interrogation Systems, Final Report 2002.  

DOE Green Energy (OSTI)

Two remote Streamwidth PIT tag Interrogation systems (SPIs) were operated continuously for over one year to test the feasibility of these systems for generating movement, migration, survival and smolt production estimates for salmonids. A total of 1,588 juvenile (< 100 mm FL) naturally produced salmonids (7 coho salmon, 482 cutthroat trout, and 1,099 steelhead) were PIT tagged above the upstream-most SPI (9 sites approximately 1 linear km each) in Fall 2001. Age at tagging for wild caught cutthroat and steelhead was 1 year. SPIs were operating before any PIT tagged fish were released in the creek. Over 390,000 detections were recorded from October 2001 to 31 July 2002. Efficiencies were site dependent, but overall detection efficiency for the creek was 97% with 95% confidence intervals of 91-100%. PIT tag detection efficiency ranged from 55-100% depending on the SPI and varied throughout the year with average efficiencies of 73% and 89%. SPI efficiency of PIT tag detection was not completely dependent on electronics noise levels or environmental conditions. Fish from all tagging locations were detected at the SPIs. Steelhead and cutthroat trout were primarily detected moving in the Spring (April-June) coincident with the anticipated smolt migration. Steelhead were also detected moving past SPIs at lower numbers in the Fall and Winter. Travel time between SPIs (downstream movement) was highly dependent on time of year. Travel time in the Spring was significantly faster (34.4 {+-} 7.0 hours) for all species than during any other time of year (763.1 {+-} 267.0 hours). Steelhead and cutthroat migrating in the Spring were the same age as those that did not migrate in the Spring. Peak of steelhead migration recorded at the two SPIs was 5/11 and 5/12 and the peak in the screw trap was recorded on 5/17. Steelhead smolt production estimates using SPIs (3,802 with 95% confidence intervals of 3,440 - 4,245) was similar to those using more standard screw trap methods (approximately 5,400). All species used the faster moving/deeper section of the creek at both SPIs. A backpack PIT tag detector was also developed and used as another remote 'recapture' for additional accuracy in estimating population survival and recapture probability. This unit was used at an approximate efficiency of 24% to survey the creek after the Spring migration. Twenty-five individual fish were re-located. All PIT tag data were used to calculate survival and recapture probabilities using the Cormack-Jolly-Seber population model. Survival for steelhead was high and recapture probability depended greatly on season. Probability of recapture was highest in Spring (29.5%) and relatively low in all other seasons (< 7% in Fall, Winter, and Summer). Wild steelhead PIT tagged in the field and returned to the laboratory had a tag retention rate of 97.6%. A laboratory study was designed to determine the effects of 3-sized PIT tags (12 mm, 20 mm, and 23 mm) on survival and growth of individuals. Survival from surgical implantation of 23 mm PIT tags was > 98% for fish (coho salmon and steelhead). Retention of 23 mm PIT tags was 100% for coho salmon and 89% for steelhead. For both coho and steelhead, growth rates during the first month were affected by tagging, but by the end of 2 months growth effects equalized for all tag sizes. Life history characteristics quantified with SPI techniques are comparable to standard techniques. For example, peaks of Spring migration for steelhead and cutthroat were amazingly similar to those reported from the screw trap. These techniques will enable application of less laborious methods which are more accurate at estimating life history parameters.

Blasting for abandoned-mine land reclamation (closure of individual subsidence features and erratic, undocumented underground coal-mine workings). Final report  

SciTech Connect

The study has examined the feasibility of blasting for mitigating various abandoned mine land features on AML sites. The investigation included extensive field trial blasts at sites in North Dakota and Montana. A blasting technique was used that was based on spherical cratering concepts. At the Beulah, North Dakota site thirteen individual vertical openings (sinkholes) were blasted with the intent to fill the voids. The blasts were designed to displace material laterally into the void. Good success was had in filling the sinkholes. At the White site in Montana erratic underground rooms with no available documentation were collapsed. An adit leading into the mine was also blasted. Both individual room blasting and area pattern blasting were studied. A total of eight blasts were fired on the one acre area. Exploration requirements and costs were found to be extensive.

Characterization of the Burma Road Rubble Pit at the Savannah River Site, Aiken, South Carolina  

Science Conference Proceedings (OSTI)

The Burma Road Rubble Pit (BRRP) is located at the Savannah River Site (SRS). The BRRP unit consists of two unlined earthen pits dug into surficial soil and filled with various waste materials. It was used from 1973--1983 for the disposal of dry inert rubble such as metal, concrete, lumber, poles, light fixtures, and glass. No record of the disposal of hazardous substances at the BRRP has been found. In 1983, the BRRP was closed by covering it with soil. In September 1988, a Ground Penetrating Radar survey detected three disturbed areas of soil near the BRRP, and a detailed and combined RCRA Facility Investigation/Remedial Investigation was conducted from November 1993 to February 1994 to determine whether hazardous substances were present in the subsurface, to evaluate the nature and extent of contamination, and to evaluate the risks posed to the SRS facility due to activities conducted at the BRRP site. Metals, semi-volatile organic compounds, volatile organic compounds, radionuclides and one pesticide (Aldrin) were detected in soil and groundwater samples collected from seventeen BRRP locations. A baseline risk assessment (BRA) was performed quantitatively to evaluate whether chemical and radionuclide concentrations detected in soil and groundwater at the BRRP posed an unacceptable threat to human health and the environment. The exposure scenarios identifiable for the BRRP were for environmental researchers, future residential and occupational land use. The total site noncancer hazard indices were below unity, and cancer risk levels were below 1.0E-06 for the existing and future case environmental researcher scenario. The future case residential and occupational scenarios showed total hazard and risk levels which exceeded US EPA criterion values relative to groundwater scenarios. For the most part, the total carcinogenic risks were within the 1.0E-04 to 1.0E-06 risk range. Only the future adult residential scenario was associated with risks exceeding 1.0E-04.

RADIOLOGICAL SURVEY STATION DEVELOPMENT FOR THE PIT DISASSEMBLY AND CONVERSION PROJECT  

SciTech Connect

The Savannah River National Laboratory (SRNL) has developed prototype equipment to demonstrate remote surveying of Inner and Outer DOE Standard 3013 containers for fixed and transferable contamination in accordance with DOE Standard 3013 and 10 CFR 835 Appendix B. When fully developed the equipment will be part of a larger suite of equipment used to package material in accordance with DOE Standard 3013 at the Pit Disassembly and Conversion Project slated for installation at the Savannah River Site. The prototype system consists of a small six-axis industrial robot with an end effector consisting of a force sensor, vacuum gripper and a three fingered pneumatic gripper. The work cell also contains two alpha survey instruments, swipes, swipe dispenser, and other ancillary equipment. An external controller interfaces with the robot controller, survey instruments and other ancillary equipment to control the overall process. SRNL is developing automated equipment for the Pit Disassembly and Conversion (PDC) Project that is slated for the Savannah River Site (SRS). The equipment being developed is automated packaging equipment for packaging plutonium bearing materials in accordance with DOE-STD-3013-2004. The subject of this paper is the development of a prototype Radiological Survey Station (RSS). Other automated equipment being developed for the PDC includes the Bagless transfer System, Outer Can Welder, Gantry Robot System (GRS) and Leak Test Station. The purpose of the RSS is to perform a frisk and swipe of the DOE Standard 3013 Container (either inner can or outer can) to check for fixed and transferable contamination. This is required to verify that the contamination levels are within the limits specified in DOE-STD-3013-2004 and 10 CFR 835, Appendix D. The surface contamination limit for the 3013 Outer Can (OC) is 500 dpm/100 cm2 (total) and 20 dpm/100 cm2 (transferable). This paper will concentrate on the RSS developments for the 3013 OC but the system for the 3013 Inner Can (IC) is nearly identical.

Method of underground mining by pillar extraction  

SciTech Connect

A method of sublevel caving and pillar and top coal extraction for mining thick coal seams includes the advance mining of rooms and crosscuts along the bottom of a seam to a height of about eight feet, and the retreat mining of the top coal from the rooms, crosscuts and portions of the pillars remaining from formation of the rooms and cross-cuts. In the retreat mining, a pocket is formed in a pillar, the top coal above the pocket is drilled, charged and shot, and then the fallen coal is loaded by a continuous miner so that the operator remains under a roof which has not been shot. The top coal from that portion of the room adjacent the pocket is then mined, and another pocket is formed in the pillar. The top coal above the second pocket is mined followed by the mining of the top coal of that portion of the room adjacent the second pocket, all by use of a continuous miner which allows the operator to remain under a roof portion which has not been shot.

Extracting value from coal mine methane  

Science Conference Proceedings (OSTI)

Emerging US policy to regulate greenhouse gas (GHG) emissions through a cap-and-trade program presents mine managers with a new opportunity to explore and develop methane utilization or abatement projects that generate value from the anodization of carbon offset credits. In addition, the rising focus on US energy security and domestic energy supply is promoting mine managers and engineers to give further consideration to the importance of their methane gas by-products. The market through which coal mine methane offset projects can be developed and carbon offset credits monetized is quickly maturing. While many methane utilization projects have previously been uneconomical, the carbon offset credit market provides a new set of financing tools for mine engineers to capitalize these projects today. Currently , there are two certification programs that have approved project protocols for CMM projects. The Voluntary Carbon Standard (VCS) offers a methodology approved under the Clean Development Mechanism, the international compliance based offset market under the Kyoto Protocol. The VCS protocol is applicable to projects that combust ventilation air methane (VAM) and methane extracted from pre-and post-mine drainage systems. The Chicago Climate Exchange (CCX), which operates a voluntary yet binding cap-and-trade market, also has an approved protocol for CMM projects. CCX's protocol can be applied to projects combusting VAM, and methane extracted from pre-and-post-mine drainage systems, as well as abandoned mines. The article describes two case studies - Developing a gob gas utilization project financed by carbon offset credits and First VAM oxidation system to be commissioned at an operating mine in the US. 1 tab., 4 photos.

Design of the Hoisting System for D-Zero Collision Hall Pit  

SciTech Connect

A hoisting rail system has been designed for lifting loads from the north sidewalk of the D0 collision hall into the collision hall pit. This engineering note documents the design. The hoisting system was conceived primarily to aid in getting heavy loads into the pit during short (less than a few days) accesses. The typical use for the hoist will be to lift a BLS power supply (120 lbs) and carrier (16 lbs) from a roll around cart on the sidewalk and onto a similar cart in the collision hall pit. The hoist system will alleviate the need for two persons to carry this heavy load up and down a narrow (24-inch) staircase. The hoisting system has a designed lift rating of 150 lbs. All members and components are well within a conservative safety factor when subjected to this loading at it's worst possible configuration, that is with it's boom cantilevered out 8 feet from the base rail. See the hoisting rail assembly sketch (in the hand calculations section) and the picture inserted below to get an orientation of the device. The hoisting system is designed using BLine 'unistrut' system components. The hoist consists of a 'base' rail that is fastened to either the northeast or northwest air handler platforms. This fixed base rail has (2) two sided trolley assemblies inserted into it's lower unistrut member. One assembly is locked in place on the base rail. Another is locked in place on the lower 'boom' rail. The trolley assemblies are free wheeling which allows boom movement in the north-south direction about 7 1/2 feet within the fixed base rail. An electric hoist hangs from the 'boom' rail on a single trolley. The hoisting system meets Fermilab Environment and Safety Manual chapter 5021 entitled 'Overhead cranes hoists and rigging'. Inclusive in that requirement is that it meets the applicable Fermilab 'work smart standards' of ANSI B30.11-1998 'Monorails and underhung cranes', and ANSI B30.16-1998 'Overhead hoists (underhung)'. The design criteria for the structural members per these standards is that static stresses shall not exceed 0.2 times the average ultimate material strength. The unistrut members are fabricated from hot rolled carbon steel. The B-Line catalog states that the minimum yield strength of the virgin material is 33,000 psi and the cold worked average yield stress is 42,000 psi. The ultimate strength of the material is not given in the catalog, but based on the description of the material and values listed in the Ryerson steel catalog, I will use a value 58,000 psi for the ultimate strength. A minimum safety factor of 5 must be achieved based on ultimate strength.

Closure Report for Corrective Action Unit 342: Area 23 Mercury Fire Training Pit Nevada Test Site, Nevada  

SciTech Connect

The purpose of this Closure Report (CR) is to provide documentation of the completed corrective action and to provide data confirming the corrective action. The corrective action was performed following the approved Corrective Action Plan (CAP) (U.S. Department of Energy [DOE], 1999b) and consisted of closure-in-place with partial excavation, disposal, backfilling, administrative controls, and post-closure monitoring. Soil with petroleum hydrocarbon concentrations above the Nevada Division of Environmental Protection (NDEP) Action Level of 100 milligrams per kilogram (mg/kg) (Nevada Administrative Code, 1996) was removed to a depth of 1.5 meters (m) (5 feet [ft]). The excavations were backfilled with clean fill to restore the site and to prevent contact with deeper, closed-in-place soil that exceeded the NDEP Action Level. According to the Corrective Action Investigation Plan (CAIP) (DOE, 1998), the Mercury Fire Training Pit was used from approximately 1965 to the early 1990s to train fire-fighting and emergency response personnel at the NTS and encompasses an area approximately 85 by 115 m (280 by 380 ft). The location of the Mercury Fire Training Pit is shown in Figure 1 and a site plan is shown in Figure 2. The Mercury Fire Training Pit formerly included a bermed bum pit with four small bum tanks; four large above ground storage tanks (ASTS); an overturned bus, a telephone pole storage area; and several areas for burning sheds, pallets, and cables. During the active life of the Mercury Fire Training Pit, training events were conducted at least monthly and sometimes as often as weekly. Fuels burned during these events included off-specification or rust-contaminated gasoline, diesel, and aviation fuel (JP-4). Other items burned during these events included paint, tires, a pond liner, wood, paper, cloth, and copper cable. Approximately 570 liters (L) (150 gallons [gal]) of fuel were used for each training event resulting in an approximate total of 136,000 L (36,000 gal) of fuel used over the life of the Mercury Fire Training Pit. Unburned fuel was allowed to pool on the ground and was left to eventually volatilize or soak into the soil. In addition, fuels from the ASTS and fuels and fluids from the overturned bus leaked or spilled onto the ground. Approximately 19 L to 38 L (5 to 10 gal) of paint were also burned monthly until sometime in the 1970s.

Determination of useful performance parameters for the ALR8(SI) plutonium pit container system  

E-Print Network (OSTI)

A thorough list of potentially useful performance parameters is generated, and a systematic method is designed to assess which parameters will provide the most significant or useful information about the long-term performance of the ALR8(SI). To generate a thorough list of performance parameters, an exhaustive literature search is performed in several key areas. These areas include the design specifications for the ALR8(SI) pit container system, as well as regulations and requirements for similar container systems used outside the weapons complex. Additionally, original parameters are identified which may also show potential usefulness if modeled or assessed. An assessment method is then created to determine, through a series of objective statements, which of the identified parameters shows pertinent, useful information about the long-term performance of the container if modeled or assessed. The results of this work will allow researchers currently modeling the performance of the ALR8(SI) to better focus their efforts. This work identifies a good starting point for researchers to begin their studies and can limit time and money wasted measuring parameters which will not provide useful information about the performance of this container system over the long-term. Additionally, this work provides an assessment method for researchers now and in the future to use when and if any new performance parameters are identified that show potentially useful information.

Successful remediation of four uranium calibration pits at Technical Area II, Sandia National Laboratories, Albuquerque, New Mexico, USA  

Science Conference Proceedings (OSTI)

The first remediation of an Environmental Restoration (ER) Project site at Sandia National Laboratories (SNL) was successfully conducted in May and June 1994 at Technical Area II. The removal action involved four Uranium Calibration Pits (UCPs) filled with radioactive or hazardous materials. The concrete culvert pits were used to test and calibrate borehole radiometric logging tools for uranium exploration. The removal action consisted of excavating and containerizing the pit contents and contaminated soil beneath the culverts, removing the four culverts, and backfilling the excavation. Each UCP removal had unique complexities. Sixty 208-L drums of solid radioactive waste and eight 208-L drums of liquid hazardous waste were generated during the VCM. Two of the concrete culverts will be disposed as radioactive waste and two as solid waste. Uranium-238 was detected in UCP-2 ore material at 746 pci/g, and at 59 pci/g in UCP-1 silica sand. UCP-4 was empty; sludge from UCP-3 contained 122 mg/L (ppm) chromium.

Carbon Sequestration on Surface Mine Lands  

SciTech Connect

Since the implementation of the federal Surface Mining Control and Reclamation Act of 1977 (SMCRA) in May of 1978, many opportunities have been lost for the reforestation of surface mines in the eastern United States. Research has shown that excessive compaction of spoil material in the backfilling and grading process is the biggest impediment to the establishment of productive forests as a post-mining land use (Ashby, 1998, Burger et al., 1994, Graves et al., 2000). Stability of mine sites was a prominent concern among regulators and mine operators in the years immediately following the implementation of SMCRA. These concerns resulted in the highly compacted, flatly graded, and consequently unproductive spoils of the early post-SMCRA era. However, there is nothing in the regulations that requires mine sites to be overly compacted as long as stability is achieved. It has been cultural barriers and not regulatory barriers that have contributed to the failure of reforestation efforts under the federal law over the past 27 years. Efforts to change the perception that the federal law and regulations impede effective reforestation techniques and interfere with bond release must be implemented. Demonstration of techniques that lead to the successful reforestation of surface mines is one such method that can be used to change perceptions and protect the forest ecosystems that were indigenous to these areas prior to mining. The University of Kentucky initiated a large-scale reforestation effort to address regulatory and cultural impediments to forest reclamation in 2003. During the three years of this project 383,000 trees were planted on over 556 acres in different physiographic areas of Kentucky (Table 1, Figure 1). Species used for the project were similar to those that existed on the sites before mining was initiated (Table 2). A monitoring program was undertaken to evaluate growth and survival of the planted species as a function of spoil characteristics and reclamation practice. In addition, experiments were integrated within the reforestation effort to address specific questions pertaining to sequestration of carbon (C) on these sites.

Superfund record of decision (EPA Region 4): New Hanover County Airport Burn Pit Site, New Hanover County, Wilmington, NC. (First remedial action), September 1992. Final report  

SciTech Connect

The New Hanover site was located on Gardner Road approximately 500 feet west of the New Hanover County Airport terminal, New Hanover, North Carolina. From 1968 to 1979, the site was used for fire-fighter training purposes. During training exercises, jet fuel, gasoline, petroleum storage bottoms, fuel oil, kerosene, and sorbent materials from oil spill cleanup were burned in a pit. During its active years, water from the pit was allowed to flow onto land surfaces. Inspections conducted after the pit was abandoned showed that most of the standing liquid in the pit was water. In addition to the burn pit area, fire-fighting activities resulted in contamination at several other site areas, including an auto burn area; a railroad tank burn area; an aircraft mock-up area; a fuel tank and pipelines area; and two stained soil areas north of the burn pit. The ROD addressed restoration of the aquifer to drinking water quality as a final action for the site. The primary contaminants of concern that affect the soil and ground water were VOCs, including benzene; and metals, including chromium and lead.

Restoring Sustainable Forests on Appalachian Mined Lands for Wood Products, Renewable Energy, Carbon Sequestration, and Other Ecosystem Services  

DOE Green Energy (OSTI)

The overall purpose of this project is to evaluate the biological and economic feasibility of restoring high-quality forests on mined land, and to measure carbon sequestration and wood production benefits that would be achieved from forest restoration procedures. In this quarterly report we present data that show the spatial distribution of carbon in mine soils. Soil carbon data from deep soil pits from grassland minelands located in Ohio, Virginia, and West Virginia were analyzed to determine the vertical distribution and variability of soil organic carbon (SOC) down to a 2-m depth. Regression analyses were used to describe and model the distribution by soil depth of C(wt%), BD{sub fines}(g cm{sup -3}), and fines (vol%) in mine soils. The volume of excavated mine soil samples was transformed in terms of costs of digging and sampling, including sample collection and preparation, and C(wt%) analysis, in order to determine the maximum cost-effective depth (MCD) for carbon inventorying on the mined sites analyzed. Based on the horizontal variation of SOC(g m{sup -2}), we determined the sampling intensity required to achieve a desired accuracy of the amount of sequestered SOC(g m{sup -2}) at certain probability levels. The MCD and sampling intensity measurements were used to determine the minimum detectable difference (MDD) of SOC(g m{sup -2}) between two consecutive carbon inventories. We also proposed a method to determine the minimum number of years before a future C inventory event is carried out so that the measured SOC(g m{sup -2}) differences were greater than MDD. We used geostatistical analyses procedures to determine spatial dependence predictability of surface SOC(g m{sup -2}) data on the minelands analyzed. Kriging techniques were used to create surface SOC(g m{sup -2}) maps for the sites in Ohio and West Virginia. The average C sequestration rate in the surface soil layer for the Ohio (age 9) sites was estimated at 124 g C m{sup -2} yr{sup -1}, and it was estimated at 107 g C m{sup -2} yr{sup -1} for the West Virginia sites (age 4). Because of the young age of the Virginia sites, 0.2 and 1 year old, we came to a decision that C sequestration rates would be inappropriate at this stage of their development, as these soils are expected to change with time.

Mining Electrification: An Investigation of the Use of Electric Equipment in the Mining Industry  

Science Conference Proceedings (OSTI)

Mining is a diverse industry that touches multiple industries with products extracted from the earth. Because of this, it is common to have one type of mining experiencing difficulty meeting demand, while another type may be cutting back operations due to poor market conditions. For example, recent economic conditions have had the sand and gravel industry in a slump because of cut backs in construction projects. At the very same time, the coal mining business was booming because there was a very high dem...

Overview of mine subsidence insurance programs in the United States  

Science Conference Proceedings (OSTI)

Research performed by the U.S. insurance industry has determined that mine subsidence is uninsurable. Consequently, the insurance industry has decided not to voluntarily offer mine subsidence insurance. The U.S. Department of the Interior has long been investigating the effects of mine subsidence. These investigations have resulted in Federal regulations and controls of mine subsidence. This U.S. Bureau of Mines report generally describes mine subsidence, the development of mine subsidence insurance programs, and the eight current mine subsidence insurance programs in the United States. The States that have these subsidence programs include Colorado, Illinois, Indiana, Kentucky, Ohio, Pennsylvania, West Virginia, and Wyoming. Major aspects of the programs include history, administrative and operational procedures, insurable structures, recognition of mine subsidence, major exclusions, claims, insurance premiums, and the economic health of each program. Addresses of agencies involved with mine subsidence insurance are also given. Information within this report can be useful for residential and commercial property owners and mine operators. States that are considered starting or have an existing mine subsidence insurance program can also use this report as a model for initiating or modifying their programs.

Soviets welcome advanced coal mining technology  

SciTech Connect

The coal production target for the Soviet Union for 1985 is 770 - 800 million tonnes. In 1981, surface mining provided 38% of output, this should increase to 40% by 1985. Soviet coal reserves are quoted as 8.6 x 10/sup 12/ tons, of which 90% are in the east. Many of the deposits are in areas where climate and transportation pose major problems. The location of the principal coal deposits is shown and their reserves are indicated. The emphasis in future production will be on surface mining, in very large units.

Probability of Liquefaction for Pit Disassembly and Conversion Facility (PDCF) Site, Savannah River Site  

Science Conference Proceedings (OSTI)

This report documents the probability of liquefaction (POL) for the Pit Disassembly and Conversion Facility (PDCF). The procedure for analysis of a critical layer of interest requires the following basic steps: (1) establish the probability of occurrence (POO) of ranges of 2.5 Hz bedrock motion based on a probabilistic seismic hazard assessment (PSHA); (2) define the critical layer that may be susceptible to liquefaction; (3) estimate distributions of cyclic stress ratio (CSR) (i.e., seismic demand) for the critical layer using site-specific soil properties corresponding to the bedrock motions; (4) estimate capacity of the critical layer based on site-specific cone penetration test (CPT) soundings and standard penetration test (SPT) blowcount data; and (5) sum the probability of liquefaction for each range of bedrock motion using empirical data correlating demand and capacity with liquefaction. The soil layer most susceptible to liquefaction is the critical layer. The critical layer is characterized by relatively low blowcount and low fines content and is established from soil layers below the water table. A key component for seismic demand is the establishment of the soil profile and it's uncertainty. The PDCF site is consistent with the 1997 SRS-specific model used to compute the site amplification database. Thus, previously derived site amplification functions reflecting the uncertainty in site properties and stratigraphy can be used to predict distributions of CSR given a specific earthquake magnitude and level of bedrock motion. The previously developed site amplification database reflects uncertainty in site response based on the large database of site shear-wave velocity profiles. Consequently, for each level of bedrock motion (from the PSHA) the site amplification database is used to establish the distribution of the expected CSR (demand) in the critical layer.

Monte Carlo Simulations for Mine Detection  

DOE Green Energy (OSTI)

During January, 1998, collaboration between LLNL, UCI and Exdet, Ltd. arranged for the testing and evaluation of a Russian developed antitank mine detection system at the Buried Objects Detection Facility (BODF) located at the Nevada Test Site. BODF is a secured 30-acre facility with approximately 300 live antitank mines that were buried in 1993 and 1994. The burial depths range from a few cm to 15 cm and the various metal- and plastic-case antitank mines each contain 6-12 kg of high explosive. Contractors who have tested their mine detection equipment at BODF include: SAIC, SRI, ERIM, MIT/Lincoln Laboratory and Loral Defense Systems. In addition LLNL researchers have used BODF to test antitank mine detection systems based on: dual-band infrared imaging, hyper-spectral imaging, synthetic aperture impulse radar and micro-impulse radar. In a blind test the Russian operated system obtained the highest score of any technology tested to date at BODF. The system is based on combining information from two separate sensors; one to detect anomalous concentrations of hydrogen and the other to detect if such anomalies also have the correct nitrogen to carbon ratio for high explosives. The detection sensitivity is set by the geometry and type of neutron moderator and filters surrounding the neutron source and detectors. Detection of hydrogen anomalies is a rapid process based on neutron scattering. The handheld instrument on the end of a wand could scan a large area at a rate of 4-5 square meters per minute. Once the hydrogen anomalies were located a second sensor was used to measure the thermal neutron excited gamma-ray spectrum at each hydrogen anomaly to determine whether that location in addition contained high concentrations of nitrogen. The second process was slower, taking up to 5 minutes for each location. The information from both sensors were then examined by the operator and a declaration was made as to whether or not the anomaly was a buried antitank mine. Although the system worked extremely well on all classes of anti-tank mines, the Russian hardware components were inferior to those that are commercially available in the United States, i.e. the NaI(Tl) crystals had significantly higher background levels and poorer resolution than their U.S. counterparts, the electronics appeared to be decades old and the photomultiplier tubes were noisy and lacked gain stabilization circuitry. During the evaluation of this technology, the question that came to mind was: could state-of-the-art sensors and electronics and improved software algorithms lead to a neutron based system that could reliably detect much smaller buried mines; namely antipersonnel mines containing 30-40 grams of high explosive? Our goal in this study was to conduct Monte Carlo simulations to gain better understanding of both phases of the mine detection system and to develop an understanding for the system's overall capabilities and limitations. In addition, we examined possible extensions of this technology to see whether or not state-of-the-art improvements could lead to a reliable anti-personnel mine detection system.

This document constitutes an addendum to the November 2003, Closure Report for Corrective Action Unit 355: Area 2 Cellars/Mud Pits as described in the document Recommendations and Justifications for Modifications for Use Restrictions Established under the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office Federal Facility Agreement and Consent Order (UR Modification document) dated February 2008. The UR Modification document was approved by NDEP on February 26, 2008. The approval of the UR Modification document constituted approval of each of the recommended UR modifications. In conformance with the UR Modification document, this addendum consists of: • This cover page that refers the reader to the UR Modification document for additional information • The cover and signature pages of the UR Modification document • The NDEP approval letter • The corresponding section of the UR Modification document This addendum provides the documentation justifying the cancellation of the URs for: • CAS 02-37-01, Cellar & Mud Pit • CAS 02-37-03, Cellar & Mud Pit • CAS 02-37-04, Cellar & Mud Pit • CAS 02-37-05, Cellar & Mud Pit • CAS 02-37-06, Cellar & Mud Pit • CAS 02-37-07, Cellar & Mud Pit • CAS 02-37-10, Cellar & Mud Pit • CAS 02-37-11, Cellar & Mud Pit • CAS 02-37-12, Cellar & Mud Pit • CAS 02-37-13, Cellar & Mud Pit • CAS 02-37-14, Cellar & Mud Pit • CAS 02-37-15, Cellar & Mud Pit • CAS 02-37-16, Cellar & Mud Pit • CAS 02-37-17, Cellar • CAS 02-37-18, Cellar & Tanks These URs were established as part of Federal Facility Agreement and Consent Order (FFACO) corrective actions and were based on the presence of contaminants at concentrations greater than the action levels established at the time of the initial investigation (FFACO, 1996; as amended August 2006). Since these URs were established, practices and procedures relating to the implementation of risk-based corrective actions (RBCA) have changed. Therefore, these URs were re-evaluated against the current RBCA criteria as defined in the Industrial Sites Project Establishment of Final Action Levels (NNSA/NSO, 2006c). This re-evaluation consisted of comparing the original data (used to define the need for the URs) to risk-based final action levels (FALs) developed using the current Industrial Sites RBCA process. The re-evaluation resulted in a recommendation to remove these URs because contamination is not present at these sites above the risk-based FALs. Requirements for inspecting and maintaining these URs will be canceled, and the postings and signage at each site will be removed. Fencing and posting may be present at these sites that are unrelated to the FFACO URs such as for radiological control purposes as required by the NV/YMP Radiological Control Manual (NNSA/NSO, 2004f). This modification will not affect or modify any non-FFACO requirements for fencing, posting, or monitoring at these sites.

Reduction of fire hazards on large mining equipment  

SciTech Connect

Although standards and regulations are in place to prevent large mining equipment fires, recent analyses of mine accident data show that mining equipment fires still occur with alarming frequency and grave consequences, particularly at all surface mines and in underground metal/nonmetal mines. Recently technological advances in fire protection, combined with the statistical data on equipment fires, led NIOSH to reinvestigate this and to improve operator safety. NIOSH demonstrated that newly developed technologies, such as dual cab fire inerting systems and engine compartment fire barriers, can greatly enhance operator safety and lessen the damage of property during large mobile equipment fires. 10 refs., 5 figs.

Mine subsidence monitoring using multisource satellite  

E-Print Network (OSTI)

Abstract- This paper demonstrates the use of differential interferometric synthetic aperture radar (DInSAR) for mine subsidence monitoring in Australia. The C-band SAR imagery acquired by ERS-1/2 and Radarsat-1 and L-band data acquired by JERS-1 were tested. As the satellites have different re-visit periods so that the mine subsidence occurred during the intervals of 1, 24, 35 and 44 days can be observed. The C-band InSAR results generally have lower coherence over vegetated areas, but the Radarsat-1 fine-beam mode data demonstrated that decorrelation can be reduced by having finer imaging resolution and shorter temporal separation. Another difficulty of DInSAR for mine subsidence monitoring is to resolve the phase ambiguity in interferogram. The L-band SAR data with comparatively longer wavelength than C-band showed it is more suitable for mining subsidence monitoring where large displacement over a small spatial extent occurs.

Industrial hygiene aspects of underground oil shale mining  

SciTech Connect

Health hazards associated with underground oil shale mining are summarized in this report. Commercial oil shale mining will be conducted on a very large scale. Conventional mining techniques of drilling, blasting, mucking, loading, scaling, and roof bolting will be employed. Room-and-pillar mining will be utilized in most mines, but mining in support of MIS retorting may also be conducted. Potential health hazards to miners may include exposure to oil shale dusts, diesel exhaust, blasting products, gases released from the oil shale or mine water, noise and vibration, and poor environmental conditions. Mining in support of MIS retorting may in addition include potential exposure to oil shale retort offgases and retort liquid products. Based upon the very limited industrial hygiene surveys and sampling in experimental oil shale mines, it does not appear that oil shale mining will result in special or unique health hazards. Further animal toxicity testing data could result in reassessment if findings are unusual. Sufficient information is available to indicate that controls for dust will be required in most mining activities, ventilation will be necessary to carry away gases and vapors from blasting and diesel equipment, and a combination of engineering controls and personal protection will likely be required for control of noise. Recommendations for future research are included.

The Biological Opinion for Yucca Mountain Site Characterization Studies required that the U.S. Department of Energy develop a Reclamation Standards and Monitoring Plan to evaluate the success of reclamation efforts. According to the Reclamation Standards and Monitoring Plan, reclaimed sites will be monitored periodically, remediated if necessary, and eventually compared to an appropriate reference area to determine whether reclamation goals have been achieved and the site can be released from further monitoring. Plant cover, density, and species richness (success parameters) on reclaimed sites are compared to 60 percent of the values (success criteria) for the same parameters on the reference area. Small sites (less than 0.1 ha) are evaluated for release using qualitative methods while large sites (greater than 0.1 ha) are evaluated using quantitative methods. In the summer of 2000, 31 small sites reclaimed in 1993 and 1994 were evaluated for reclamation success and potential release from further monitoring. Plant density, cover, and species richness were estimated on the C-Well Pipeline, UE-25 Large Rocks test site, and 29 ground surface facility test pits. Evidence of erosion, reproduction and natural recruitment, exotic species abundance, and animal use (key attributes) also were recorded for each site and used in success evaluations. The C-Well Pipeline and ground surface facility test pits were located in a ''Larrea tridentata - Ephedra nevadensis'' vegetation association while the UE-25 Large Rocks test site was located in an area dominated by ''Coleogyne ramosissima and Ephedra nevadensis''. Reference areas in the same vegetation associations with similar slope and aspect were chosen for comparison to the reclaimed sites. Sixty percent of the reference area means for density, cover, and species richness were compared to the estimated means for the reclaimed sites. Plant density, cover, and species richness at the C-Well Pipeline and UE-25 Large Rocks test site were greater than the success criteria and all key attributes indicated the sites were in acceptable condition. Therefore, these two sites were recommended for release from further monitoring. Of the 29 ground surface facility test pits, 26 met the criterion for density, 21 for cover, and 23 for species richness. When key attributes and conditions of the plant community near each pit were taken into account, 27 of these pits were recommended for release. Success parameters and key attributes at ground surface facility test pits 19 and 20 were inadequate for site release. Transplants of native species were added to these two sites in 2001 to improve density, cover, and species richness.

Lessons and challenges from mining retail e-commerce data  

E-Print Network (OSTI)

Abstract. The architecture of Blue Martini Software’s e-commerce suite has supported data collection, transformation, and data mining since its inception. With clickstreams being collected at the application-server layer, high-level events being logged, and data automatically transformed into a data warehouse using meta-data, common problems plaguing data mining using weblogs (e.g. sessionization and conflating multi-sourced data) were obviated, thus allowing us to concentrate on actual data mining goals. We briefly review the architecture and discuss many lessons learned over the last four years and the challenges still facing us. The lessons and challenges are presented across two dimensions: business-level vs. technical, and throughout the data mining lifecycle stages of data collection, data warehouse construction, business intelligence, and deployment. The lessons and challenges are more widely applicable to data mining domains outside retail e-commerce. Keywords: Data mining, data analysis, business intelligence, web analytics, web mining, OLAP,

An analysis of tank and pump pit flammable gas data in support of saltwater pumping safety basis simplification  

DOE Green Energy (OSTI)

Hanford Site high-level waste tanks are interim stabilized by pumping supernatant and interstitial waste liquids to double-shell tanks (DSTs) through a saltwell pump (SWP). The motor to this SWP is located atop the tank, inside a pump pit. A pumping line extends down from the pump motor into the well area, located in the salt/sludge solids in the tank below. Pumping of these wastes is complicated by the fact that some of the wastes generate and retain potentially hazardous amounts of hydrogen, nitrous oxide, and ammonia. Monitoring of flammable gas concentrations during saltwell pumping activities has shown that one effect of pumping is acceleration in the release of accumulated hydrogen. A second effect is that of a temporarily increased hydrogen concentration in both the dome space and pump pit. There is a safety concern that the hydrogen concentration during saltwell pumping activities might approach the lower flammability limit (LFL) in either the tank dome space or the pump pit. The current Final Safety Analysis Report (FSAR) (CHG 2000) for saltwell pumping requires continuous flammable gas monitoring in both the pump pit and the tank vapor space during saltwell pumping. The FSAR also requires that portable exhauster fans be available by most of the passively ventilated tanks to be saltwell pumped in the event that additional air flow is required to dilute the headspace concentration of flammable gases to acceptable levels. The first objective of this analysis is to review the need for an auxiliary exhauster. Since the purpose of the exhauster is to diffuse unacceptably high flammable gas concentrations, discovery of an alternate method of accomplishing the same task may provide cost savings. The method reviewed is that of temporarily stopping the saltwell pumps. This analysis also examines the typical hydrogen concentration peaks and the rates of increase in hydrogen levels already witnessed in tanks during saltwell pumping activities. The historical data show that these rates and maximum concentrations are so low as to make it unlikely that the LFL concentration would ever be approached. The second objective of this analysis is to review the data provided by two separate flammable gas measurement systems on each tank being saltwell pumped to see if there is an unnecessary redundancy. Eliminating redundant measurement systems would provide cost savings if the quality of data and resultant margin of safety during saltwell pumping activity are not compromised.

Evaluation of Roof Bolting Requirements Based on In-Mine Roof Bolter Drilling  

SciTech Connect

Roof bolting is the most popular method for underground openings in the mining industry, especially in the bedded deposits such as coal. In fact, all U.S. underground coal mine entries are roof-bolted as required by law. However, roof falls still occur frequently in the roof bolted entries. The two possible reasons are: the lack of knowledge of and technology to detect the roof geological conditions in advance of mining, and lack of roof bolting design criteria for modern roof bolting systems. This research is to develop a method for predicting the roof geology and stability condition in real time during roof bolting operation. Based on this information, roof bolting design criteria for modern roof bolting systems will be developed for implementation in real time. For the prediction of roof geology and stability condition in real time, a micro processor was used and a program developed to monitor and record the drilling parameters of roof bolter. These parameters include feed pressure, feed flow (penetration rate), rotation pressure, rotation rate, vacuum pressure, oil temperature of hydraulic circuit, and signals for controlling machine. From the results of a series of laboratory and underground tests so far, feed pressure is found to be a good indicator for identifying the voids/fractures and estimating the roof rock strength. The method for determining quantitatively the location and the size of void/fracture and estimating the roof rock strength from the drilling parameters of roof bolter was developed. Also, a set of computational rules has been developed for in-mine roof using measured roof drilling parameters and implemented in MRGIS (Mine Roof Geology Information System), a software package developed to allow mine engineers to make use of the large amount of roof drilling parameters for predicting roof geology properties automatically. For the development of roof bolting criteria, finite element models were developed for tensioned and fully grouted bolting designs. Numerical simulations were performed to investigate the mechanisms of modern roof bolting systems including both the tension and fully grouted bolts. Parameters to be studied are: bolt length, bolt spacing, bolt size/strength, grout annulus, in-situ stress condition, overburden depth, and roof geology (massive strata, fractured, and laminated or thinly-bedded). Based on the analysis of the mechanisms of both bolting systems and failure modes of the bolted strata, roof bolting design criteria and programs for modern roof bolting systems were developed. These criterion and/or programs were combined with the MRGIS for use in conjunction with roof bolt installation.
