充填体力学性态和支撑作用的研究日益深入,人们对它的认识也在逐渐加深。文章总结了室内实验和国内外一些矿山实测结果,阐述了尾砂胶结充填体和粗颗粒非胶结充填体的力学特性和对围岩的力学作用。实践证明,充填体是一种有效的支护材料,采矿工作者可以根据它的力学特点、矿岩条件、回采方式等客观因素选择廉价的充填料,提高充填矿山的经济效益。
The research on mechanical properties and supporting effect of filling body has been deepened day by day, and people's understanding of it is gradually deepening. The article summarizes the laboratory experiments and the results of some domestic and foreign mines, and expounds the mechanical properties of the tailings cemented filler body and the coarse-grained non-cemented filling body and the mechanical effects on the surrounding rock. Practice has proved that the filling body is an effective support material, mining workers according to its mechanical characteristics, ore rock conditions, the objective factors such as the choice of low-cost filling materials to improve the economic benefits of filling mines.
