基于微震监测的浅埋矿山地压活动规律研究

Research on the Earth Pressure Activity of the Shallow Buried Mine Based on Microseismic Monitoring

我国民采矿山的矿体埋藏浅、空区分布复杂,地压灾害事故时有发生。针对传统地压监测手段存在的缺陷,将微震监测系统应用于浅埋矿山,并对地压活动规律及灾害预测进行研究。结果表明,微震监测系统能够三维实时反应井下地压活动状况,据此可有效识别和圈定地压活动风险区域,对于矿山安全生产具有一定的参考价值。

There private mine in our country with the characteristics of shallow ore mines, empty area distribution complex, the ground pressure disasters happen occasionally. Aiming at the shortcomings of the traditional press-monitoring tools, the microseismic monitoring system mining is applied to the shallow buried mines, the law of earth pressure activities and disaster prediction are researched. The research results show that, the overall situation of ground pressure can be showed in real-time with three-dimensional form, on the basis of the situation, the ground pressure risk areas are identified and delineated effectively. The research results in this paper can provide reference to ensure mine safety production.
