APPLICATION OF MICROSEISMIC MONITORING TO CHARACTERIZE OVERBURDEN MOVEMENT IN ISOLATED LONGWALL MINING
Characterization of rock failure propagation is one of the most essential requirements in mine microseismic (MS) monitoring for dynamic hazard prevention. This paper illustrates the application for MS monitoring to characterize the fracture process associated with overburden movement in the mining progress of LW10302, an isolated working face in B.D. Coal Mine. The results show that the seismic signals correspond to the different failure mechanisms which show different characteristics in waveform features, and have demonstrated that fracture propagation monitored by MS monitoring fits well with the movement of the overburden structure. The study will greatly benefit the understanding of stress distribution around the longwall face and the control of rock burst hazards in mines.
