Reasonable Workface Mining Height under Shallow Cover and Thin Strata Geological Condition in Sanbula Coal Mine

摘要：

A numeric software called FLAC3D is applied to simulate the fracture of upper strata while 2-2 coal seam is mined by hydraulic powered support in Sanbula coal mine where the shallow coal bed is covered by thin strata. Then a reasonable mining height of workface is deduced by analyzing the change of abutment pressure.The result indicats that the reasonable range of cutting height is 3.7 ~4.7m when implementation of integrated mechanized mining coal seam 2-2 in area of the Sanbula.
