| 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.

| Abstract: | 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 t... |
