The process of fully mechanized coal seam mining under aquifers and surface water bodies has been a challenge in recent years for different countries. During the evolution subsidence overburdening rock mass movement above longwall goaf, there is always potential risk connecting water-conducting fracture zone with aquifers. inflows mine’s roadways have negative impact on productivity working faces pose significant hazards to miners event inrush. Therefore, assessment height water-flowing fractured an important scientific practical significance. background this study Xinhu Coal Mine Anhui Province, China. In number 81 area during 815 longwall, inflow occurred due fractures sandstone overburden rock. experience successful implementation inrush control method by horizontal regional grouting through multiple directional wells described paper. This proposes algorithm from aquifers, based ANSYS 17.2 simulation complex anticline bedding. It was found that safety factors stress strain parameters can be used as criteria failure aquifer zone. For 817 panel Mine, probability indicates low occurrence
