The Numerical Simulation And Seismic Monitoring Research Of Mining Induced Fault Activation

At the present time,coal mine safety has become a major concern ,solve coal mine safety problems are becoming urgent, however in coal mine industry ,fault activation as influence coal and gas outburst is one of the important factors. Roadway excavation, the front seam mining can induce the activation of the fault, the impact of mining is the basic reason,caused complex changes within the coal and rock, caused fault activation even slip, not only Critical life and safety of miners, but also Resulted in the loss of coal and the State. First, this paper based on the fact of Mining 62110 Coal Mine B10 fault F10-5 in XinZhuangZi Coal Mine, used simulation software RFPA^2D , selected the proper parameters, reappeared the whole process of the fault F10-5's activation, and analyzes the process of its internal development; And then analyzed the actual monitoring results from ESG, got the useful data to help making proper plan to Avoid accidents; Finally, after the mutual comparison of the numerical simulation and the results of microseismic monitoring, we found RFPA can reappear the fault activation, add to the ESG's real-time monitoring is a new way to research fault activation, and reduce the loss which caused by the fault activation.
