Response characteristics of key strata during the periodic weighting process in Dongjiahe coal mine were investigated using micro-seismic (MS) monitoring. Fracture types identified through moment tensor inversion. Finally, fracture mechanism roof was revealed from a microscopic viewpoint. The results show that there are three concentrations MS events distributed along dip direction. And two eve...
