开发矿业,首先要正确认识和评价矿床,在普查、勘探、开采各个阶段进行及时的经济评价,以便择优开发。 (一)矿床经济评价中考虑的主要因素 1.社会主义计划经济的影响。我国国民经济是有计划、按比例发展的。因此,首先应考虑国家对某种资源的需要程度与发展远景。如化肥工业产品逐渐向高效复合肥料方面发展,那些开采、加工条件好的磷矿床,经济价值相应就高。 2.矿床地质条件及开采方法。一般说来,适宜露天开采的,采矿方法较单纯、采场生产能力较大,矿山生产规模大的,相应的矿床经济价值就高。
To develop mining industry, we must first of all understand and evaluate the deposit correctly, carry out timely economic evaluation in all stages of the census, prospecting and mining in order to optimize development. (A) of the main factors considered in the economic evaluation of the deposit 1. The impact of socialist planned economy. Our national economy is planned and pro-rata. Therefore, we should first consider the extent of the state's need for certain resources and their development prospects. For example, fertilizer industrial products are gradually developing into efficient compound fertilizers. Those phosphate mines with good mining and processing conditions have a correspondingly higher economic value. 2. Deposit geological conditions and mining methods. In general, suitable for open-pit mining, mining methods more simple, larger production capacity of stopes, large-scale production of mines, the corresponding economic value of the deposit is high.
