基于覆岩空间结构理论的冲击地压预测技术及应用
|
摘要
基于覆岩空间结构理论的基本思想,结合力学分析,研究了"S"型覆岩空间结构的岩层组成、运动规律、应力分布特征,探索了基于覆岩空间结构理论的冲击地压预测方法.基于山东华丰煤矿微地震监测的结果,证明除了受构造、煤柱等影响区域外,当"S"型覆岩空间结构在工作面推进至单工作面"见方"、双工作面"见方"、三工作面"见方"阶段,由于采场上方覆岩空间结构相互连通,其运动范围和烈度增大,更容易诱发冲击地压.结合华丰矿1410工作面的开采实际,预测了冲击地压发生的时间和地点.
Based on the overlying multi-strata spatial structure theory and mechanics analysis,presented the rules of "S" shape spatial strata structure movement and mining stress distribution.Coal out-burst forecasting based on "S" shape spatial strata structure movement was studied.According to microseismic monitoring result in Huafeng Coal Mine in Shandong Province,coal out-burst will happen when the advancing distance of longwall face is equal to one,two or three times length of longwall face respectively.During these periods,mined areas approach to square shape while "S" shape spatial strata structures acting strongly.Based on this viewpoint,predicted the time and position of coal out-burst in No.1410 longwall face of Huafeng Coal Mine.By using large diameter and deep drill hole in seam and deep drill hole with blasting in roof at those danger areas,the No.1410 longwall face safely advanced through those danger areas.During those periods the microseismic monitoring system detected very strong mine quakes.
