露天开采发展到现阶段的特点是出现新的趋向——在复杂矿山技术条件下,要尽可能地减少矿床开采对周围环境的不利影响。因此,在着手矿山开采之前,必须具有明确的概念:即矿山开采场地要留下什么,那就是留下的土地必须具有良好的状态,或者保持矿山开采前的原状。除此之外,完成全部土地复原的费用应该最少。在这种条件下,占用的土地和复田作业的土地的规模和进度就显得很重要了。
The development of open pit mining to the present stage is characterized by the emergence of a new trend - in the conditions of complex mining technology, to minimize the negative impact of the mining on the surrounding environment. Therefore, before proceeding with the exploitation of mines, it is necessary to have a clear idea of what remains of the mined area, that is, the land left behind must have a good condition or remain in the same condition as before mining. In addition, the cost of completing the entire land restoration should be minimal. Under such conditions, the size and progress of the occupied land and the land for the rehabilitation of the land become very important.
