煤矿冲击地压预测及解决方法

Study on Coal Mine Rock Burst Prediction and Solutions

我国煤矿开采已逐渐进入深部开采,冲击地压问题日益凸显。冲击地压发生条件极为复杂,具有突发性,危害严重,探求冲击地压的预测及解决方法成为煤矿企业所面临的重要课题。针对这一课题,运用钻屑法做现场试验,有效预测试验矿井风巷存在冲击危险,并对冲击地压防治进行了简要描述。

At present coal mining in our country gradually came into the deep mining, then rock burst problem became increasingly prominent. Rock burst occurrence conditions were extremely complex, with a sudden, serious harm. Exploring rock burst prediction and solutions became an important issue to coal mining enterprises. Based on the field test for drilling bits method, effective prediction of testing mine air roadway impact risk was made, and the rock burst prevention and control were briefly described.
