Mine water hazard genesis and its prevention and control technology for deep coal seam mining mines
In order to promote the safety mining and sustainable development of deep coal seam mining,we explore the key technology for water prevention and control during deep coal seam mining.Firstly,the genesis of water hazard and the impor-tance of quality control of mine water were introduced.Secondly,the advantage and disadvantages of detection technologies of mine water hazard and their applicable ranges were discussed,including underground direct current detection method,transient electromagnetic detection method,and audio electric penetration perspective detection method.Then,water preven-tion and control technologies were introduced,such as filling mining,waterproof gates,coal seam floor reinforcement grou-ting,and Ordovician limestone drainage and pressure reduction.Finally,emphasis was placed on water quality control meas-ures,including water quality monitoring and analysis,water treatment technology,and water quality regulation.
