摘要
巨大采空区垮塌造成的灾害,已经严重制约了矿山的安全生产。针对采用一般监测手段已远不能满足巨大采空区稳定性监测需求的情况,利用微震监测技术,对某矿巨大采空区稳定性进行监测,并根据将近一个月的监测数据,对采空区的稳定性和采空区周边的断层活化情况进行了分析。分析结果在该矿采空区稳定性监测中得到很好的应用。同时在检波器安装过程中,利用可拆卸安装装置进行安装,进一步拓展了检波器在井下的可重复利用性,大大降低了工程成本。
Huge goaf collapse caused by disaster has seriously affected safe production in mines. The conventional monitoring method can not meet the huge goaf stability monitoring demand. In this paper,the great stability of mined out area has been surveyed by the microseismic monitoring technique. According to the monitoring data of nearly a month,the stability of the goaf and the fault activation surrounding the goaf have been analysised. The analysis results applied very well in the goaf stability monitoring in the mine. At the same time in the detector installation process,the installation is carried out with a disassemble device. The detachably mounted device used in the underground can be repeatedly used,greatly reducing the cost of the project.
