Analysis on distribution characteristics of surrounding rock miningstress in close distance coal seams of Malan Mine
LIU Chun-bo
Abstract:According to the mining conditions of the close distance coal seams of southern No.5 mining district in Malan Mine,a FLAC3D numerical model was built referring to geostress measurement results.The distribution characteristics of mining stress under different mining conditions were studied.Simultaneously,based on the simulation results,the reasonable layout of roadway in the lower coal seam was selectively analyzed after the upper coal seam was mined,the research results can offer reference for roadway surrounding rock control for close distance coal seam mining.
