引言在金属鑛床鑛层群开采中,鑛山企业的产鑛量常常不是以开采一个鑛体而是开采两个、三个甚至更多的鑛体来保证。因而就产生了究竟同时要开采多少鑛体,以及每个鑛体分配多少产量的问题。同时开采几个鑛体的主要原因是:仅开采一个或两个鑛体达不到坑口规定的出鑛任务;也达不到鑛石质量要求。因为企业规定成品任务,要求坑口具有一定鑛石质量的出鑛量。所以在开采中,一方面要保证坑口鑛石产量,另一方面又要保证采出的鑛石质量,同时还要保证鑛体正确的开采顺序。这一问题的研究是具有重要意义和 INTRODUCTION In the mining of metal deposits, the mining enterprises often do not produce more ore by one orebody but rather mine two, three or more ore bodies. Thus there arises the question of exactly how many ore bodies to be mined at the same time and how much production each orebody should allocate. The main reason for the simultaneous exploitation of several ore bodies is that only one or two ore bodies can not be mined to reach the mine-out task specified by the pit and the ore quality requirements can not be met. Because the provisions of the finished product business mission, requires a certain amount of ore quality mine exit amount. Therefore, mining, on the one hand to ensure the production of pit ore, on the other hand but also to ensure the quality of the ore taken, but also to ensure the correct sequence of mining ore. The study of this issue is of great significance
