密集巷道群冲击地压防治研究

Research on Prevention and Control of Rock Burst in Dense Roadway Group

对山西曙光船窝煤矿5470Y工作面密集巷道群冲击地压防治进行了研究。通过分析工作面动力现象,掌握了造成冲击地压的原因,并有针对性地采取了缺陷转换成缺陷体、大直径钻孔卸压和钻孔爆破卸压等综合防治措施。采用钻屑法对防治效果进行检验,结果表明,所采取的措施有效消除了工作面密集巷道群的冲击地压危险。

This paper studied the prevention and control of rock burst of dense roadway group in 5470 Y working face of Shuguang Chuanwo Coal Mine in Shanxi Province.By analyzing the dynamic phenomena of working face,the causes of rock burst were grasped,and comprehensive prevention measures such as defect transformation,large diameter borehole pressure relief and borehole blasting pressure relief were adopted.The drilling cuttings method was used to check the control effect.The results showed that the measures adopted effectively eliminated the danger of rock burst of dense roadways in working face.
