Basic geological and analytical properties of selected coal seams for coal interface detection. Information circular/1993
One important element of the U.S. Bureau of Mines computer-assisted mining research program is the development of a reliable coal interface detection (CID) system. Several candidate CID concepts currently being investigated by the Bureau include use of natural gamma radiation (NGR), vibration, passive infrared, video, and radar. To help establish which CID sensor technologies need to be developed for a given seam, the Bureau has collected geological and mining practices data from over 460 underground and surface mines in the United States. Also, over 500 coal and rock samples have been obtained for laboratory analyses of ash content, sulfur content, heating value, and NGR. The Bureau's findings indicate that the immediate roof strata in 81 percent of the underground mines and 93 percent of the surface mines are made up of shale, draw slate, or claystone. The immediate floor strata in 88 percent of both the underground and surface mines consist of fireclay, shale, draw slate, or claystone.
