摘　　要：为减小地应力对煤矿开采影响,以大安山煤矿为研究对象,通过现场地质调查、对采煤工作面及巷道的矿压观测结果分析,提出以下方法:合理划分采区;合理安排开采顺序;采用无煤柱护巷;加快采煤工作面的推进速度;选择合理的回采巷道支护形式等。自实施以来,效果较好,保证了煤矿的安全开采。In order to reducing the influence of geo-stress on coal mining,several methods were put forward on the basis of geological investigation and the analysis of observation result of underground pressure in mining-face and roadway.They were： rationally designing mining zones and mining sequence,designing roadway without coal pillar,increasing mining speed and selecting rational roadway supporting manner.Application effect was good and safety mining was realized.
