Mine filling production line

‌The mine filling production line is a process of using mining solid waste materials mixed with cementitious materials such as cement to form a certain strength filling body, and transporting the filling material to underground goaf or underground space. The main purpose is to support rock layers, control ground pressure activities in the mining area, prevent surface subsidence, improve the stress state of mining pillars, and ensure the recovery and reuse rate of mineral resources. By filling, surface subsidence can be effectively controlled, surface buildings, railways, and water bodies can be protected from damage, soil erosion can be reduced, mine life can be extended, and resource extraction rate can be improved.
