In 2008, "Research on Water Prevention and Control in Underground Mining of Lindai Bauxite Mine in Guizhou" won the third prize of science and technology in China's nonferrous metal industry. Many accidents of water inrush, mud inrush and well flooding occurred in the production process of the mine, which caused the mine depth extension to stagnate. After carrying out supplementary hydrological investigation, our company put forward the scheme of "surface + underground joint prevention and control", which successfully solved the hydrogeological problems affecting the development of deep resources. At present, the mine project has been successfully developed to the lowest production elevation.
