摘　　要：为了解决某煤矿西一采区某新村压煤问题,对7164工作面正常回采进行了采动影响预计分析,结果显示某新村内地表下沉量满足不了控制要求。根据该村与7164工作面位置关系,通过建筑物压煤开采方法对比分析,认为7164工作面部分区域限厚开采可有效控制该村范围内地表下沉量,并对7164工作面限厚范围进行了优化设计,达到了预期的效果。In order to solve problem of coal under village of the western one mining area of one coal mine,and then forecast analysis of mining influence of 7164 working face mining,the results showed that surface subsidence amount of one new village could not meet control demand.According position relationship between the village and 7164 working face,and also contrastive analysis was proceed of mining method of coal under village,the conclusion that some local area mining under limited thickness of 7164 working face could controll surface subsidence within village scope,so optimization design was also proceed for limited thickness scope of 7164 working face,the prospective results was reached.
