随着水砂充填采矿法在金属矿山的广泛应用,对充填体的研究显得愈来愈重要。充填体的作用一个是维护已采空区,另一个是可做为采场内的工作平台。因此,除要求充填体必须具有足够强度外,还需要较小的沉降。本文拟对充填体的自然沉降问题进行探讨。 (一)充填体沉降的机理充填料是由松散物质构成的。其物理性质与其他连续介 With the extensive application of water sand filling mining method in metal mines, the research of filling materials is becoming more and more important. The role of a filling body is to maintain the area has been mined, the other can be used as stope work platform. Therefore, in addition to requiring the filling body to have sufficient strength, less settling is required. This paper intends to investigate the natural settlement of the filling body. (A) the mechanism of the filling body filler material is composed of loose material. Its physical properties and other continuous media
