Abstract

In order to provide the basis for deep mine stope design and disaster prevention, microseismic and coal stress monitoring techniques were used to measure the surrounding rock fracture law and stress distribution in deep mine stope. According to the microseismic monitoring, after the mine enters the deep mining stage, the range of overlying strata movement expanded, the overlying strata are divided into several characteristic layers, which are periodically fractured along with the working face advance. And the influence distance of the movement of the overlying strata on the front of the working face is far beyond the influence distance of the shallow mining stage. According to the joint analysis of vibration and stress monitoring data, it can be known that the real-time warning of rockburst risk can be acknowledged through the joint monitoring of microseismic and stress.
