矿物原料最充分而优质的利用,与开采时的矿石损失贫化定额及其计算方法的改进密切相关,并取决于矿山地质与采矿技术条件。 据对兹拉托乌斯特—别罗夫露天矿近五年(1975—1980年)资料的统计分析,已能定量阐述矿体厚度m、台阶高度H、矿体倾角α、台阶坡面角β等因素对矿石损失Π和贫
The most adequate and high-quality utilization of mineral raw materials is closely related to the quota of ore loss and depletion during mining and the improvement of its calculation method, and depends on the technical conditions of mining geology and mining. According to the statistical analysis of the data of the Zlato Uster-Beloru Opencast Mine in the recent five years (1975-1980), the thickness of the ore body m, the step height H, the inclination α of the ore body, the step slope angle β and other factors on the ore loss Π and poor
