摘要
Because the coal mine rocks are sensitive to water environment, the presence of groundwater will greatly reduce the strength of the rock mass, thus reducing the stability of the open-pit slope, which is not conducive to the safe production of open-pit mines. Therefore, significantly reducing the underground water level inside the open pit slope is beneficial to improving the strength of the slope rock mass and the final slope stability. It is the most effective safety control method for the mine and can significantly improve the intrinsic safety of the mine. At the same time, the sump and drainage pipe at the bottom of the open-pit coal mine stope are eliminated, the open-pit drainage system is simplified, and the economic benefit of the coal mine is improved.
