Abstract

Abstract: According to the near distance coal seams of southern five mining area in Malan mine, taking the means with the stress test results. the distribution characteristics of mining stress of the near distance coal seams with different mining conditions were studied using FLAC3D numerical simulation method. Simultaneously, based on the simulation results, the reasonable layout of gateway in the lower coal seam was selectively analyzed after the upper layer coal seam mined, the reference research results can be a valuable reference to surrounding control for the mining of near distance coal seams. Keyword: near distance coal seams; mining stress; distribution characteristics; layout of gateway
