1、根据自然条件选择露天矿边帮排水系统运用矿床的复杂性分类来选择露天矿边帮的排水系统。因此,要考虑到矿床的自然条件和采矿工作的各个发展阶段;特别要注意有利于强化每个具体矿床的排水因素。第一类矿床,坚硬和半坚硬的非喀斯特岩石。这类矿床的渗透性一般都很低,实际上并没有因水的作用而降低坚固性,允许水在边坡自由渗出。这种状况允许建设露天矿时,通常
1, according to the natural conditions of the surface mine drainage system to help select the complexity of the deposit classification to choose the edge of the open pit drainage system. Therefore, the natural conditions of the deposit and the stages of development of the mining operation should be taken into account; special attention should be paid to the drainage factors conducive to strengthening each specific deposit. The first type deposits, hard and semi-rigid non-karst rocks. The permeability of such deposits is generally very low, in fact not because of the role of water and reduce the ruggedness, allowing water free seepage on the slope. This condition allows the construction of opencast mines, usually when
