摘　　要：本文以梁宝寺煤矿5304工作面为研究背景,以F6、DF319断层组成的地垒构造区域为研究对象,借助相似模拟实验、FLAC3D数值模拟、现场实测,研究综放工作面过地垒构造区域时采动影响分析,并采用顶板预裂爆破切顶、大直径钻孔协同卸压技术,提出地垒构造条件下综放工作面矿压监测方案与解危卸压方案。现场矿压实测数据表明工作面矿压得到了有效的控制,能够满足工作面安全生产的需求。In this paper,No.5304 Face of Liangbaosi Coal Mine was taken as the research background,and the horst structure area composed of F6 and DF319 faults was taken as the research object.With the help of similar simulation experiment,FLAC3D numerical simulation and field measurement,the mining influence analysis of fully mechanized caving face passing through the horst structure area was studied,and the roof pre-splitting blasting roof cutting and large diameter drilling collaborative pressure relief technology were adopted.The mine pressure monitoring scheme and the solution pressure relief scheme of fully mechanized caving face under the condition of horst structure were put forward.The field mine compaction test data showed that the mine pressure of the working face was effectively controlled,which could meet the needs of the safe production of the working face.
