充填料被输送到采场之后,逐渐形成整体的充填体.充填体作为支护围岩的手段,它不仅可以控制采场的两邦围岩的局部破坏,而且更重要的是可以防止大规模的岩石移动.由于这些目的,就要求充填体必须具备一定的强度.而提高以松散物料组成的充填体的强度,其关键之一是提高充填体的密实程度(或体重).另外,采用充填采矿法的采场,为了达到维护围岩及防止岩层大面积 After the filling material is transported to the stope, a complete filling body is gradually formed, and as a means of supporting the surrounding rock, the filling body can not only control the local damage of the two state rocks in the stope, but more importantly can prevent the large-scale Of the rock to move .For these purposes, requires the filler must have a certain strength, and to improve the strength of the filler body composition of loose material is one of the key is to increase the density of the filling body (or body weight) .In addition, the use of filling Mining law stope, in order to achieve the maintenance of rock and rock to prevent the large area
