要评价一个矿山开采设计是否做到经济合理,所涉及的方面是很多的,影响的因素也是极其复杂的,笔者认为仅仅看投资多少,成本高低是不全面的,还应该看该设计对矿产资源的科用程度如何?已经勘探的工业储量在矿山开采设计中到底被利用多少?暂时还不能被利用的有多少?在开采条件相当的情况下,如果被设计利用的程度越高,将来开采时,采出的矿石就越多,它标志着这个设计在经济合理方面做得比较好一些,反之,它标志着这个设计在经济合理
To evaluate whether a mining design is economically reasonable, there are many aspects involved, and the influencing factors are extremely complicated. I think it is not comprehensive to see how much the investment is and how much the cost should be. What is the degree of scientific and technological use of the exploration of industrial reserves in the mining design in the end how much? For the time being can not be used? Under the conditions of the same mining conditions, if designed to use the higher the degree of future mining , The more ore is mined, indicating that the design is doing better economically and on the contrary, it signals that the design is economically justified
