Based on the monitoring data from the IMS system, the present article intends to propose a classification method of rock mass seismic disasters, which tend to be resulted by such factors, as the spatial distribution of microseismic events and the spatial distribution of microseismic incidence. In order to predict and control the disasters of the gob destabilization, we used to introduce the IMS microseismic monitoring system into the Yongshaba coal mine. First of all, we have managed to make an exploration of the microseismicity features in the whole mine scale through a statistical analysis, ...
