摘要
煤矿开采深度逐渐加深,发生冲击地压显现的矿井也明显增多,给矿井的生产安全带来了极大的隐患。本文以大同煤矿集团忻州窑矿8914综放工作面为研究对象,总结分析了冲击地压综放工作面高应力集中区掘进、回采期间的微震信息及矿压显现特征,设计了相应的治理措施,取得了较好的应用效果,有效地防治了冲击地压事故的发生。
The mining depth of coal mining gradually deepens, and there are obviously more mines with pressure bump behavior, which brings great hidden trouble to the production and safety of the mine. In this paper, 8941 fully mechanized caving face of Xinzhoukiln Mine, Datong Coal Mining Group is taken as the research object, and the tunneling in the high stress concentration zone, the extraction of seismic information and the characteristics of mine pressure bump behavior are analyzed and summarized. The corresponding control measures are designed, and good application effect is achieved, effectively preventing the occurrence of rock bust accident.
