Thoughts on mine water control and treatment in Yushen mining area

In order to scientifically explain the water gusting(bursting) events with large water inflow in Yushen mining area and provide basic information for mine water control and treatment, this paper analyzes the water bursting events and large mine water gusting situations in recent years, and questions such as formation mechanism of large water inflow in mine, hydrogeological property of red soil layer and accuracy of mine inflow prediction are put forward. It expounds how to break through the "mine field" scope and study groundwater system and water bursting source in terms of regions and focus on weakly water-rich aquifers such as Yan'an Formation, Zhiluo Formation, and Luohe Formation sandstone aquifer, looking for the water bursting source from diversion fissure zone. And the paper evaluates the hydrogeological conditions of each rock(soil) layer, permeability evolution of mining-induced strata(aquifers), as well as explore the source prevention of mine water disasters and ideas of regional governance. Based on the above thoughts, it puts forward that the hydrogeological conditions and the contribution to the water gusting(bursting) of coal mine should be recognized regionally to reveal the formation mechanism of large water inflow in mine. Hydrogeological complementary exploration to identify aquifer, water-resisting layer and their spatial occurrence relationship accurately should be strengthed. It is to explore the development law of water-conducting fracture zone under the environment of large mining height and large mining surface and put forward the prevention and control measures for mine water disasters based on strong runoff zone of groundwater with regional recognition and locally rich water area, which provides reference and help for the water disaster control and treatment in Yushen Coal Mine.
