Hanging Wall of the Fault Tilting Waterresisting Key Strata Model Wang Yuhe1 Zhang xinglei2 Wang Houchen2 Cheng Jiulong1,3 Guo Wei1 1Key Laboratory of Mine Disaster Prevention and Control Shandong University of Science and Technology Qingdao 266590,China 2Shandong Xinwen Mining Company Xintai 271202,China 3State Key Laboratory of Coal Resources and Safe Mining China University of Mining and Technology Beijing 100083,China Abstract: In order to make inrush coefficient method more accurate and effective in the coal floor water bursting evaluation, taking into account the interaction between the mine floor and the fault under the influence of mining, establishing the model of hanging wall tilting resisting key strata, solving the deflection of the sheet model under the action of the overburden rock stratum and confined water. The reasonable of the model was analyzed through numerical simulation software FLAC3D, the results showed that: the hanging wall sloping impermeable layer model key was reasonable in the water inrush evaluation of the mine floor near the fault.
