充填是采矿作业基本环节之一,它在很大程度上决定矿石回采的效率和安全。在人工充填工艺中,为了隔离采空区要花费大量的作业时间,尤其是采用分层采矿法充填所消耗的工时更多。将充填区与巷道隔离开来可以采用各种结构的挡墙:固定式的(混凝土的和木材的)和移动式的(充气的、充水的等)。挡墙的面积和充填料的压力是计算挡墙的原始数据。充填料之所以具有压力是 Filling is one of the basic aspects of mining operations, which largely determines the efficiency and safety of ore recovery. In the manual filling process, it takes a lot of work time to isolate the goaf, especially the time taken by the stratified mining filling. A variety of structural barriers can be used to isolate the filling area from the roadway: fixed (concrete and wood) and mobile (inflatable, water filled, etc.). The area of ​​the retaining wall and the pressure of the filling material are the original data for calculating the retaining wall. The reason why the filling material is under pressure
