露天采选企业产生大量的废石和尾矿,占用大量的土地并恶化周围生态环境。采用地下采矿和地下选矿的新工艺可实现经济效益高和对生态环境无影响的无废采选生产。本文叙述了对原苏联3个矿床应用此新工艺进行的技术经济计算和对比。
Open-pit mining companies produce large amounts of waste rock and tailings, occupy a large amount of land and worsen the surrounding ecological environment. The use of underground mining and underground beneficiation of the new process can achieve high economic efficiency and no impact on the ecological environment of non-waste production.
