Application Summary AI generated
This standard specifies the technical requirements for solid-filling operations during fully-mechanized coal mining, including material preparation, filling process control, and quality inspection. It is applied in underground coal mines using mechanized longwall mining methods to backfill mined-out areas with solid waste materials such as gangue or fly ash. The standard ensures safe, efficient, and environmentally responsible extraction by reducing surface subsidence and managing mining waste.
