在贫化损失率的计算中,为了要求得貯矿量,即采下后存放在采矿声的矿石,必须要利用松散系数(其他的勘探阶段,也同样的要用到松散系数)计算其金属量、矿石量等。松散系数作计算贫化率与损失率的过程中是一项不可缺少的资料。松散系数的计算公式是(松散后的体积)/(原岩体积) 松散系数的值,一般都是用试验求得的。即选定能华表该采场(或岩层、中段、区城)岩矿特性的地点,将掌子面修平进行爆破后,测得其原岩体积和松散(即爆破后)体积来进行计算。
In the calculation of the depletion loss rate, in order to obtain the ore reserves, that is, the ore stored in the mining sound after mining, it is necessary to calculate the metal content by using the loose coefficient (other exploration stages and the same loose coefficient) Volume, ore volume and so on. The loose coefficient is an indispensable piece of information in the process of calculating the rate of dilution and loss. Loose coefficient is calculated as (loose volume) / (raw rock volume), the value of the loose coefficient, are generally obtained experimentally. That is, the site where the rock properties of the stope (or the rock formation, the middle section and the district city) are selected can be calculated by flattening the face of the face and blasting the rock and measuring the volume of the original rock and the volume after the blasting (ie, after blasting).
