摘要
为了有效防止南屯煤矿93_下04掘进工作面发生冲击地压,通过理论分析和现场实测的方法,分析自重应力、构造应力、采空区应力对掘进工作面产生冲击地压的影响,采用多因素耦合评价法划分出冲击危险区级危险程度,并提出解危及检验措施。
In order to eitectively prevent the nantun colhery 93- 04 tunneling faces impact grounu pressure, through theoretical analysis and field measurement, the method of analysis of gravity stress, tectonic stress, the stress of goal pressure influence on tunneling working face ,multi-factor coupling evaluation method is used to obtain impact of danger zone and degree of danger, and puts forward solution to endanger inspection measures.
