Abstract: In order to reduce the discharge of coal mine solid waste from the source and achieve green production, Zhongyu Mine Design adopts advanced and efficient underground gangue sorting and underground filling methods according to the coal mine conditions and mining layout. This paper describes the design of underground sorting and underground filling systems After discussion, it is expected that gangue will not come out of the well after implementation, effectively solve the problem of underground gangue discharge from wells, and provide an effective reference for mine design and production.
