矿物原料的合理利用是一个最重要的国民经济和社会问题,这个问题的解决要牵涉到一系列复杂的工程经济问题。这是由必须提高生产效益以及矿物资源不可再生决定的。为评价地下资源合理利用的效果,采用包括经济、生态和社会等因素在内的综合标准是适宜的。开发矿床时首先要考虑这样一些经济因素,诸如:为满足当前的社会需要并考虑未来的变化情况,对矿物原料开采和加工所要求的规模;利用地下资源的现代技术经济水平和科技
The rational utilization of mineral raw materials is one of the most important national economic and social issues. The solution to this problem involves a series of complicated engineering economic problems. This is determined by the need to increase production efficiency and the non-renewable mineral resources. In order to evaluate the effect of rational utilization of underground resources, it is appropriate to adopt comprehensive standards including economic, ecological and social factors. Some of the economic factors to consider when developing a deposit include the following: the scale required for the extraction and processing of mineral raw materials to meet current social needs and to account for future changes; the use of the modern technical and economical level of underground resources and technology
