摘要
在综合分析级差矿利的概念、分类、产生的原因基础上 ,提出了标准开采指标、劣等矿山开采指标等参数的计算方法 ,给出了级差矿利的测算模型 ,并对某一矿区 (11对矿井 )
On the basis of the comprehensive analysis of the concept,classification and origin of differential profit of mining,a calculation method for the mining performances of both standard and inferior mines is suggested.A calculation model for differential profit of mining is developed and has been used in a real calculation for a mine district (where there are eleven pairs of mines).
