Research on Water Resistance of The Hanging Wall of the Fault Tilting Water-resisting Key Strata Model

摘要

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.
