INTRODUCTIONThe coal mine of Baohetang is located in Shaodong County, Hunan Province. The Longtan group, up to 220 m in thickness, contains 4 coal seams, and the lower 2 seams, generally speaking, are not suited for mining, whereas the upper 2 seams are recoverable, thicknesses of which are separately 0.60 m and 1.19 m on an average.
