按照采矿工程的规模来说,建筑材料工业是主要的采矿业之一。苏联建材工业的露天矿每年开采30亿吨以上矿产。最近几十年的强化开采导致了生产矿床的储量逐渐枯竭。而目前正在勘探的矿床大都不具备良好的开采条件。在开采含水矿床时采用降低水位的方法,要求综合研究技术、经济和生态诸问题。其中就排水本身来说,技术上并不很复杂。但是,这是很费动 According to the scale of mining engineering, the building materials industry is one of the major mining industries. The open-pit mine in the Soviet Union’s building materials industry mines more than 3 billion tons of ore each year. The intensive mining in recent decades has led to the depletion of the reserves of the productive deposits. Most of the deposits currently being explored do not have good mining conditions. The method of lowering the water level in the exploitation of water-bearing deposits requires a comprehensive study of technical, economic and ecological issues. One of the drainage itself, technically not very complicated. However, this is very laborious
