在井工开采中,冲击地压是发生在岩石及煤介质内最危险的现象。随着我国煤矿井工开采深度的不断增加,冲击地压问题日益突出,它已构成新的煤矿自然灾害。我省开滦矿区已面临冲击地压威胁,其他大部分矿井也已进入深部水平开采,因此,认识、研究和防治冲击地压的问题逐渐提到日程上来。本文想从我省深部煤层埋藏条件出发,结合开滦唐山矿发生冲击地压的情况,浅谈我省井工开采中冲击地压发生的可能性。
In underground mining, rockburst is the most dangerous phenomenon that occurs in rock and coal media. With the increasing mining depth of coal mine in our country, the problem of rock burst is becoming more and more prominent. It has formed a new natural disaster of coal mine. Kailuan mine area in our province has been facing the threat of rock burst. Most other mines have also entered deep horizontal mining. Therefore, the issue of understanding, researching and preventing rock burst has gradually been brought to the agenda. In this paper, starting from the burial conditions of deep coal seams in our province, combined with the impact of rock excavation in Tangshan mine Kailuan situation, on the possibility of rock burst in our province.
