摘要
金源煤矿1321工作面具有冲击地压倾向性,通过煤层高压注水,借助电磁辐射仪和钻屑法监测,结合深孔卸压爆破的综合防冲措施,安全生产20万t煤炭资源。
There is a rock burst tendency in the 1321 face ofJin yuan Coal Mine, through the high -pressure water is injected into the coal seam, by means of electromagnetic radiometer and the method of drill cuttings for monitoring, combined with a comprehensive preventing rock burst measure of deep - hole pressure release blasting, 20 million tons of coal has been safely produced.
