Title: Determination of immediate roof at mines of the Kutahya-Omerler coal basin, Turkey

Abstract

The estimation of the relations between excavation height, longwall advance rate, convergence around a longwall in the roof-soil direction, and load distribution on support is reported, that are of specific importance for selecting support type. The principal attention is focused on determination of the immediate roof height that depends on the mobility characteristics of overlying rocks and governs mainly the stopping convergence and load intensity on the support. Numerical modeling, laboratory and field experiments are undertaken in this study, which included evaluation of composition and physicomechanical properties of rocks, assessment of stress-strain state of rock mass and of the immediate roof height, measurements of disintegration and bulking factor of overlying rocks, convergence of stopping floor and roof, and loads on hydraulic legs of supports. The study parameters obtained by different methods for the Omerler Mine are presented.

  • Mine roof fall characteristics of 250 falls in 5 different room-and-pillar coal mines, located in Pike, Martin, and Floyd counties, Kentucky, were investigated to determine the relationship of selected parameters associated with roof failure and the assumed condition of the mine roof before failure. The selected parameters used in the study included: presence of cracks and water before the occurrence of fall, sloughing of coal ribs, floor heave condition, type of roof support distance to coal face, and time of occurrence of fall after initial coal extraction. In addition, 8 research hypotheses, utilizing multiple linear regression techniques, were generated tomore » test the relationship among the selected parameters and mine roof condition. The results indicated that the vast majority of falls portrayed some presence of water before the actual fall, occurred in less than 30 weeks after initial coal excavation, located usually greater than 30 m from nearest coal face, gave evidence of cracks in mine roof before occurrence of fall, generally portrayed a good roof condition before the fall, showed presence of sloughing of coal ribs, and gave no occurrence of floor heave before occurrence of fall. In terms of the characteristics of the original support systems in the mine roof falls studied, most roofs were either supported by mechanical-anchor bolts or resin or full-column bolts; very rarely did the roof appear to fail if supported by posts or cribs. A detailed inspection of the hypothesis and model comparison results gave supporting evidence that the condition of the roof is not dependent on the usual indicators of potential failure, such as presence of cracks and moisture. Hence, a combination of factors that are not easily accessible to measurement, are the dominant factors in the determination of roof fall-potential areas. (15 refs.)« less
  • One of the major problems in surface mining of coal is the stability of disposed overburden materials. Geotechnical considerations are thus very important in rational planning for disposal, reclamation, treatment, and utilization of mine waste material. The subject of this study is the stability of spoil piles at open pit coal mines located in the Central Anatolia, Turkey. The coal is produced from two adjacent open pits. While a large portion of the spoil piles dumped at the Central Pit has experienced slope failure, no spoil pile instability has been experienced at the South Pit. This article outlines the resultsmore » of field and laboratory investigations to describe the mechanism of the spoil pile failure in the Central Pit and the geotechnical design considerations for the spoil piles at the South Pit based on the experience gained from the previous spoil failures. Limit equilibrium analysis carried out for the large-scale spoil failure indicated that deep-seated sliding along the interface between underclay and dragline spoil piles and rotational slip through the overburden spoil material may be all occurring simultaneously as water migrates through these areas. Sensitivity analyses revealed that spoil pile instability is not expected at the South Pit when the current spoil placement method is used as long as the generation of high water pressures in the spoil piles is not permitted. Comparisons between the results of finite element analysis and long-term monitoring data also confirmed the results of sensitivity analyses and indicated a vertical deformation associated with compaction of the spoil material.« less
  • Current underground mining practice often requires that a predetermined amount of coal be left on the roof of the mined-out area. The need to leave such coal occurs on both continuous miner and longwall sections and is derived from considerations of ground control, quality control, machine guidance, or simply good operating practice. Efforts at measuring boundary coal thickness have been employed mechanical, nucleonic, and energy adsorption and reflection methods. The nucleonic methods have found application in operations in the United Kingdom, the United States, the former Soviet Union, and Poland. Natural gamma devices are currently the instrument of choice, andmore » several successful installations exist. The calibration of natural gamma background (NGB) instruments must be carefully maintained, and they cannot be used in areas where a NGB radiation is not present. This radiation is ordinarily present in the fine-grained sedimentary rocks that bound many coal seams.« less
  • Roof support, an important aspect of ground control, involves maintaining roof competency to ensure a safe and efficient mining environment. Wide variability in rock quality and stress distributions requires a systematic approach to roof support design that satisfies specific goals. The success of past roof support in reducing the incidence of roof falls has been primarily attributed to safer roof bolting practices. However, roof falls continue to be the number one occupational hazard in underground coal mines. This US Bureau of Mines report presents a general overview of roof bolting and other roof support methods used in the United States.more » Characteristics of bad roof and associated roof failure theories are briefly presented as background to roof support. Methods of detecting and monitoring roof behavior and/or bolt performance provide essential feedback on roof support requirements. A discussion follows on roof bolt design that assimilates roof and support parameters into useful equations or nomographs to help decide what bolt types to use and how they should be installed under different roof conditions. 35 refs., 8 figs.« less
