本文对标准块段经济品位的概念和应用问题,从探采结合的角度,进行初步的讨论。一、标准块段的涵义“标准块段”系指在矿石储量规模上等于矿山年产量的地质块段。而矿山年产量在技术经济上是与所勘探的矿床大小和生产年限合理配套的。在技术可能条件下,矿山经济年产量(A_经)可按矿山经济生产年限(t_经)进行计算(后面讨论),并与一般概念上的大、中、小型矿山正常服务年限进行平衡。鉴于地质勘探部门在储量计算中划分的地质块段有的偏大。有的按设计和生产矿山的年产量计
In this paper, the concept and application of the standard block economic grade, from the perspective of exploration and mining, to conduct a preliminary discussion. First, the meaning of the standard block “standard block” refers to the size of the ore reserves equal to the annual output of geological blocks. The annual output of mines is technically and economically matched with the size and production period of the ore deposits under exploration. Under technically feasible conditions, annual economic output (A_N) of the mines can be calculated according to the economic life of the mines (discussed later) and balanced with the normal service life of large, medium and small mines . In view of the geologic exploration department in the calculation of reserves in the geological block some large. Some according to the design and production of the annual output of mines
