摘　　要：针对皖北煤电集团祁东煤矿71煤层,应用FLAC2D软件模拟综放沿空掘巷留设不同宽度煤柱时围岩位移和应力的大小,确定了71煤层相邻工作面区段沿空掘巷留设煤柱的合理宽度,对类似综放沿空掘巷合理位置的确定具有参考价值。In view of the conditions of 71 coal seam in Qidong Coal Mine of Wanbei Coal and Electric Power Group Corporation Ltd. , the displacements and stresses of surrounding rock of roadways drove along goaf and with different width coal pillars are simulated by use of FLAC^2D software, and the reasonable coal pillar width is determined for roadway driving along goaf between adjacent working surface sectors in 71 coal seam, this provides reference to the determinate of reasonable position of similar roadway driving along goaf.
