【Abstract】 In this paper, new methods was put forwarcl to control the water hazard in mines on the condition that the rock formation of seepping water into mines is the low permeability aquifer. The methods are vacuum well discharge method, air injection increasing pressure discharge methods and the combination method of two ways metioned above. Furthermore, the principles of the methods were elaborated, the efficiency of the methods was demonstrated and the implementation processes of the technology of the methods were designed.更多还原
