摘要
桃山煤矿针对冲击矿压动力灾害预测技术难题,采用钻屑法进行冲击危险性预测为基础,并结合现场实际提出煤层爆破和断顶爆破解危技术措施,取得较好的技术效果。
According to the technical problems in Taoshan Coal Mine rockburst forecasting dynamic disasters,the impact of risk based prediction method of drilling bits,and combined with the actual proposed coal seam blasting and blasting off top crisis measures,achieved better technical effect.
