摘要
近年来鹤岗矿业集团公司的南部5个煤矿相继发生冲击地压现象,且造成不同程度的财产损失,通过采用冲击危险倾向性测试、冲击危险指数评估、电磁辐射观测方法,采用煤体注水、深孔爆破、采空区断顶等解危手段,实现了煤矿的安全生产。
This paper describes the emersions of undergrotmd pressure eruption happened in series in Hegang Coal Industry Group Ltd., which made certain loss in property. Bg the measures such as measuring the risk tendency of underground pressure eruption, evaluating risk index of underground pressure eruption, observing electromagnetic radiation, water injection in coal seam, long drill hole blasting, roof broken in gob area etc., realized safe coal production.
