在苏联,社会生产量的增长,引起国民经济在各种矿物资源利用方面的需求不断提高。需求量的增长,产生一种明显的趋势——从矿物原料中获得单位最终商品产品的费用增加。这主要由下述原因造成:在所采矿石中,主要回收组分的含量减少;所经营和开发矿床的矿山地质和经济地质填图条件复杂化;环境保护费用增加。
In the Soviet Union, the increase in social production has caused the demand of the national economy for the utilization of various mineral resources to continuously improve. The increase in demand leads to a clear trend of increasing the cost of obtaining the final commercial product of the unit from mineral raw materials. This is mainly due to the following reasons: the content of the major recovery components in the ore taken is reduced; the geology and economic geology mapping conditions of the mines operated and developed are complicated; the cost of environmental protection is increased.
