Abstract: Taking Meiyukou Coal Mine as the engineering background, the damage situations of two main roadways and surrounding area roof failure were monitored by KJ551 microseismic monitoring system in order to protect the panel roadway safety. The stability of roadway and its temporal and spatial characteristics of microseismic energy were studied. The results show that the energy value of microseismic event has great relationship with coal rock force and concentration degree. The greater the stress and the higher the degree of concentration will lead greater degree of coal and rock deformation and failure when microseismic event occurs, and the higher energy will be released. The mining activities of the upper coal seam will lead the rupture and instability of internal roof of lower coal seam. Roadway roof stability is closely related with the upper coal seam mining. The damage degree of mining activities on different height layers of the rock is different, the fracture degree of the low rock is bigger,but the high rock is smaller.
