摘要
应用24Model对2011年后发生的10起冲击地压事故的不安全动作与物态进行分析,系统研究了导致煤矿冲击地压事故的不安全行为原因。结果表明:80%的冲击地压事故点埋深超过800 m,50%事故点位于断层区域,90%的冲击地压事故发生在国有重点煤矿。可将导致冲击地压事故的发生过程按生产管理活动划分为2个阶段:第1阶段是高应力集中区的形成过程和易生条件;第2阶段消除冲击地压危险性过程。并得到以冒险作业、防冲措施失效为主的7个导致消除冲击地压危险失效的不安全动作类别。
In order to study the behavioral causes of coal mine rock burst accidents,24Model was applied to analyze the unsafe acts and physical causes of 10 typical rock burst accidents occurred after 2011.The results show that the depth of 80%of the rock burst accidents is over 800 m,50%of the accident points are located in the fault area,and 90%of the rock burst accidents occur in the state-owned key coal mines.The occurrence process of the rock burst accidents can be divided into two stages:the formation process of the high stress concentration zone and the process of eliminating the rock burst risk.Seven categories of unsafe actions,which mainly include risk operation and failure of anti-impact measures,are obtained to eliminate the failure of rock burst hazard.
