| Abstract: | Based on the measured stress results with hydraulic fracture method in a mine, the variation of waterresisting ability for floor rock mass under effecting of geostress and rock pressure is analysed and discussed. The waterresisting mechanism of impermeable layer and interferential zone which is easy for water inrush is discussed. The relations of geostress, pressures of confined water and crack propagation are analysed. The relations of initial geostress and seam floor water irruption are obtained. |

| Keywords: | geostress rock pressure water irruption of seam floor hydrofracture |
