چکیده انگلیسی
Xiaojihan coal mine is a typical high-intensity mining in Western China. The real-time monitoring of deformation and failure for the working face was carried out by using IMS microseismic monitoring system. The change process of microseismic parameters such as microseismic event rate, energy release, apparent volume, energy index, Schmidt number, b value and coefficient of seismic response and the relationships with the surrounding rock failure were studied. This research indicates that some parameters have obvious precursory characteristics before the large scale failure. The predictive periods were divided by these parameters, and Schmidt number has the highest predictive sensitivity, b value the second, energy index the third. Coefficient of seismic response and energy release have no direct contact with the excavation volume of ore body, but depend on the mine pressure behavior of working face.
