综合利用地下资源,矿山无废料,这是国民经济中的一项重要的任务。 在露天开采的矿床中,剥离下的废石可由各个专门的企业回收利用,作为生产各种建筑材料(碎石、砂等)的原料。 在露天矿,象剥离的废石这种原料,一般足可以为建筑工业建立大型的原料基地,并可保证以工业规模长期地生产建筑材料。 遗憾的是,在企业中对废石附带回收利用的工作,还处于极低的水平,没有超过开采
Comprehensive utilization of underground resources, mining waste, which is an important task in the national economy. In open-pit mined deposits, the stripped waste rock can be recycled by specialized companies as a raw material for the production of various building materials (gravel, sand, etc.). In opencast mines, raw materials such as peeled waste rock are generally sufficient to build a large base of raw materials for the construction industry and to ensure long-term production of building materials on an industrial scale. Unfortunately, the work of recycling and recycling waste rock in enterprises is still at a very low level and has not surpassed the exploitation
