斯维尔德洛夫斯克矿业学院对新西拜露天矿在生产后期采用箕斗提升的经济效果进行了研究。该问题是在对矿山工程发展方式进行经济分析的基础上,采用方案比较法加以解决的, 同时考虑了时间因素。各方案比较时,后期的基建费用总额均按同一时间(1967年)进行折算。根据新西拜露天矿的地质和采矿技术条件(最终深度为440米,边坡角为40—42°,平
The Sverdlovsk School of Mines conducted a study of the economic effects of the skiphook improvement at the New West Bay open pit mine in the later stages of production. The problem is based on the economic analysis of the development mode of the mine project, which is solved by the program comparison method, taking into account the time factor. The various programs, the latter part of the total infrastructure costs are converted at the same time (1967). According to Xinxi Bai open-pit mine geological and mining technology conditions (the final depth of 440 meters, the slope angle of 40-42 °, flat
