本文根据对龙凤矿的不同回采工作面进行的现场试验、利用自制的围压装置进行的实验室试验、以及理论计算结果,试验研究出钻屑法一整套确定冲击危险指标和判断冲击危险程度的方法和手段,具体给出了龙凤矿开采冲击地压危险煤层检测标准和冲击指标,并在生产中应用。 Based on the field tests conducted on different mining face of Longfeng Mine, the laboratory tests using self-made confining pressure devices and the theoretical calculation results, a set of drilling cuttings method is established to determine the impact hazard index and judge the impact risk level Methods and means, the paper gives concretely the testing standards and impact indexes for the dangerous coal seam under the conditions of rock burst in Longfeng Mine, and applies it in the production.
