摘要
冲击地压是危害煤矿安全生产的重大灾害之一。为了保证矿井的安全生产,要加强对冲击地压的研究。本文分析了孤岛工作面发生冲击地压的主要机理,通过对23070工作面顶底板岩性、微震事件分布等进行分析研究,得出其发生冲击地压主要是地板参与型冲击,并依此采取相应的防冲措施。
Rock burst is one of the major disasters that endanger the safety of coal mine production.In order to ensure the safe production of the mine,we should strengthen the study of the rock burst.This paper analyzed the main mechanism of rock burst in the isolated working face,and based on coal seam and its roof and floor lithologic,microseism distribution,the main types of rock burst are obtained.And then taken corresponding measures to prevent it.
