Abstract: It is a engineering effort roadblock coal resources mining under rich aquiferous rock layers, flood incident of colliery will be caused by improper method. Base on the Hydro-geological and Engineering Geology Investigation,comprehensive analysis on structure construction of engineering rock mass, TEM, pumping experiment and communicating test were applied to research water-rich property of every aquifer and the hydraulic channels in Shizuishan colliery. In order to ensure safety in mining production, the measure that base on defending and combine the two ways of dredging and plugging is worked out. It takes a new direction for coal mining under rich aquiferous rock layers.
