Abstract: In the process of coal mining, it is inevitable to produce a large number of gangues, which not only occupy the land, but also cause great damage to the surface ecological environment. In order to solve a series of problems caused by gangue discharge, Shendong mining area starts from the source of mining design, through optimizing the roadway design and equipment matching to reduce the generation of gangue at the source, the gangue that can be separately loaded and transported in the underground is discharged through the construction of the special gangue discharge roadway in the underground, and these gangues are reused in the underground engineering, realizing the zero rise well of gangue in the underground. Through the implementation of the above measures, the technical problems of environmental pollution caused by underground waste disposal and waste discharge are solved.
