摘要
为了确定采掘平衡的定量比例关系 ,按照开采准备程度 ,将水平开拓、采区准备和回采工作面的三类巷道圈定的各级别储量称为开拓矿产量、准备矿产量和回采矿产量 ,简称“三量”。用“三量”来反映采掘工程的经济技术指示、生产准备情况和采掘关系 ,以保证生产的正常接续 ,以此确定制硝系统的年生产规模、企业工业硝水浓度。
Three categories ore reserves such as development, b lo cked out and recovery ore tonnage are called after three tonnages which reflect economic-technical indexes of mining and tunneling works production preparation and relationship between mining and tunneling in order to guarantee normal opera tion and determine annual production scale and density of glauberite solution.
