摘要
结合老虎台矿的68002#掘进工作面具有局部冲击地压危险性,实施了煤体高压注水技术措施,并进行了效果考察分析,有效地降低了掘进工作面的冲击地压危险性。
Combining the Laohutai coal mine 68002#tunneling working surface has the burst risk of local impact.The implementation of the technical measures of coal of high pressure water injection and the effects were analyzed and effectivly reduces the tunneling working surface of rock burst risk.
