摘要
忻州窑矿8935工作面推进过程中冲击地压灾害异常活跃,现有技术手段不能合理有效的防治冲击地压的问题。文章以冲击地压诱发成因分析为基础,提出钻屑法、矿压法、电磁法、微震法、指数法等预测预报技术和超前泄压、强制放顶、加强支护、合理避让等治理技术并进行现场应用。应用后冲击地压事故发生起数明显下降,实现了矿井的安全高效生产。
Abstract：In this paper, based on the analysis of the causes of the induced pressure induced by the ground pressure, the method of cuttings, ore pressure, electromagnetic method, and so on are put forward. The results show that the rockburst method is not effective and effective. , M icroseismic method, index method and other forecasting technology and advanced pressure relief, fnrced caving, strengththing support, reasonable to avoid and other treatment techniques and field applications. After the application of the impact of the number of accidcnts occurred significantly decreased, to achieve the safety and efficient production of the mine.
