摘要
依据大同地震台网的地震记录,计算出了燕子山煤矿采空区塌陷引起的矿山地震和老杨沟煤矿顶板坍塌的地震基本参数;通过灾害调查确定了塌陷中心的位置,并对老杨沟煤矿顶板坍塌的成因进行了分析。得出利用地震监测台网不仅可以定位矿山地震,而且还可以定位矿山地震引发的塌陷,对矿区生产安全起到了一定的作用。
Based on the seismic records of the Datong seismic network, this paper calculates earthquake basic parameters of the mining shock caused by Coal Mine collapse in Yanzishan goal and collapsed roof of Laoyanggou Coal Mine. Through the disaster investigation, the center position of the collapse is determined, and the cause of the roof collapse of Laoyanggou Coal Mine is analyzed. The conclu- sion is that the earthquake monitoring stations can not only position mine earthquake, and can also position the collapse that caused by mining shock, which played a certain role in mine safety production.
