摘要
冲击地压是一种复杂的矿井动力现象,一直是岩体力学及矿山防治研究的难点之一。近年来随着煤矿采深的增加,出现冲击地压显现的矿井明显增多,给矿井生产和安全带来了极大的威胁。根据龙家堡201工作面顺槽出现的冲击地压现状,通过RFPA数值模拟研究,设计了钻孔卸压方案,通过现场实施,取得了较好的效果。
Rock burst is a kind of complex mine dynamic phenomena and is always one of the difficulties on rock mass mechanics and mine control and research.In recent years,with the increase of excavation depth of coal mining,the numbers of mine which occur rock burst also increased obviously,which threaten the mine production and safety greatly.Based on rock burst status in working face NO.201 Longjiapu coal mine,through the study of RFPA numerical simulation,drillhole pressure relief program is designed,a good effect is obtained through site implementation.
