随着露天矿采矿工作面的下降,采掘工作带的范围将缩小,这就需要在不断缩小的场地上使采矿工作集中,而不因此降低露天矿的生产能力。在地质、水文地质和工程地质条件复杂的情况下,剥离和回采工作要与保证边坡稳定和疏于措施同时进行。这种情况又在很大程度上对工作的组织和时间上的配合提出更严格的要求。在面积有限的露天矿中,采矿工作面下降很快,在矿床开采的最初年代就形成了非
As the surface of mining operations in the open pit declines, the extent of the mining work zone will narrow, requiring the concentration of mining operations on a shrinking site without reducing the production capacity of the open pit mine. In the case of complex geological, hydrogeological and engineering geological conditions, stripping and recovery work should be carried out at the same time as slope stability and neglect. This situation, to a large extent, places more stringent requirements on the organization of work and the coordination on time. In a limited area of open-pit mines, the mining face declined rapidly and formed non-existent during the earliest years of the ore deposit
