Abstract: Under the condition of close distance coal seam group of ascending mining, the lower coal seam outside fault recovery when starting cut upper strata damage rule has its own characteristics. Using High-precision microseismic monitoring technology and theoretical analysis method to study qiuci A6-103 working face through the upper coal seam goaf eye, the migration regularity of rock burst. Underground microseismic event waveform is divided into five species; When working face through the lower goaf, the energy of seismic events and frequency is divided into process of "normal - fast - bursts reduction". Through the analysis of the spatial microseismic events distribution ，fracture zone height is mining height 14 times
