The "Drainage Project of Sanmenxia Mine Duancun-Leigou Bauxite Mining Project of Chinalco" completed in 2013 won the high-quality project of China Nonferrous Metals Industry (ministerial level) in 2016-2017. The project includes the investigation and construction of 14 drainage wells, with a hole diameter of 425mm and a maximum hole depth of 440m, which is difficult to drill and requires high pumping test and equipment. After the drainage well was put into use, the water level of limestone karst aquifer dropped greatly, which ensured the safe development of mine infrastructure shafts and roadways, and also solved the water use problem of mines and local villagers.
