根据1981～1985年以至1990年以前的苏联经济及社会发展的基本路线,要求黑色冶金采选企业提高回收率并增大精矿中含铁的质量百分比。为了解决这个任务,要求对原料基地、物质成分参数变异性特征和工艺性质,具有较全面的了解。信息资料的完整程度和可靠程度,主要取决于对各勘探阶段矿石工艺性质的了解程度;计划的待采矿段上生产取样网点的网度;小型工艺试验的数据资料和地质-工艺图及各种剖面图的可靠程度。 According to the basic line of Soviet economic and social development from 1981 to 1985 and before 1990, the black metallurgical mining enterprises are required to increase the recovery rate and increase the mass percentage of iron in the concentrate. In order to solve this task, it is required to have a comprehensive understanding of the raw material base, the characteristics of variability of the material composition parameters, and the nature of the process. The completeness and reliability of the information and information depend mainly on the degree of understanding of the nature of the ore process at each exploration stage; the degree of netting of the sampling sites to be produced on the planned area to be mined; data and geotechnical-process drawings and various The degree of reliability of the profile.
