苏联和国外地下开采应用充填采矿法积累的经验证明,这种采矿方法很有前途。采用这种采矿法不仅可以提高优质有用矿物的回采率,改善回采作业的安全条件,而且也可能使地层内部和地下水保持地质动力平衡,使地表土层保持耕作能力,为废弃尾矿生产打下基础。然而采用充填采矿法由于需要消耗大量的胶凝材料和骨料,致使充填料的成本很高,因此扩大充填采矿法的应用范围受到了限制。由于非标准骨料质量很差并且充填混合料搅拌不充分,致使胶凝材料耗量增大,这是造成充填料费用高的原因。
Experience gained from the application of the Fill Mining Act to underground mining in the Soviet Union and abroad has proved promising. Using this mining method can not only improve the recovery rate of high quality and useful minerals and improve the safety conditions of the mining operations, but also keep the geodynamic dynamic balance within the strata and groundwater, maintain the cultivation ability of the surface soil layer, and lay the foundation for abandoned tailings production . However, the use of filling mining method due to the need to consume a large amount of cementitious materials and aggregates, resulting in high cost of filling material, so expand the scope of application of filling mining method has been limited. Due to the poor quality of non-standard aggregates and inadequate mixing of the filling mixture, resulting in increased consumption of cementitious material, which is caused by the high cost of filling material.
