公式中,N、L、T、l、u都是常数,在一定时间内,q也可以认为是常数。因此,提高Q的关键在于提高m、K值。 1)、有效采场数N的确定方法有三种: 第一种:按矿块摆布法直接剔除选取。即:在中段平面图上按设计要求划分若干个采场,再扣除勘探程度不够、边缘部分、断层影响、保安矿柱或某些技术上原因还不能采的采场数后,剩下的采场都叫有效采场。 In the formula, N, L, T, l, u are all constant, in a certain period of time, q can also be considered as a constant. Therefore, the key to improve Q is to improve m, K value. 1) There are three ways to determine the effective number of storages N: The first one is to select directly according to the mining method. Namely: in the middle plan according to the design requirements of a number of stopes, and then deduct the degree of exploration is not enough, the edge of the fault, the impact of security pillars or some technical reasons can not mining the number of stopes, the remaining stope All are called effective stope
