Mechanism and prevention measures of mine flood disaster in the first mining area of Dazhuyuan Bauxite Mine

Dazhuyuan Bauxite Mine is the benchmark mine that successfully applies the coal system comprehensive mining and fully mechanized mining technology to the non-ferrous system for the first time.The mine topography and geomorphic conditions are conducive to artoflow drainage.However, during the construction and production process of the mine, underground seepage accidents caused by heavy rains have occurred many times in the rainy season, which seriously affects the safety of mine production.Based on the understanding of hydrogeological conditions in mining area, this paper analyzes the disaster mechanism of mine seepage caused by atmospheric rainfall from the aspects of water source and channel of flooded well, and puts forward some feasible prevention measures in combination with mining technology, hoping to be beneficial to mine safety production.
