摘要
根据采区应力分布规律、冲击地压发生的可能性指数和其隶属度,针对冲击地压发生强度和地点进行了评价,相应设计了爆破卸压、钻孔卸压、煤层预注水卸压的三种技术措施,达到了解危的效果。
According to stress distribution rules and degree, strength blasting pressure and location of the rock burst were evaluated. relief, bolehole pressure relief, and advanced rock burst probability index and membership Then three solving crisis measures were listed： water injection pressure relief.
