浅析窄脉采矿中的贫化率对工业矿量效益的影响
|
摘要
红透山矿床随着厚大矿床的相继结束,矿山进入边、远、窄、贫开采阶段,随着采场矿脉的收窄,采矿效率降低而采矿成本随之增加。从工业矿量效益角度出发,结合工程经济原理中的盈亏平衡点分析法,分析窄脉采矿中影响工业矿量效益的关键因素贫化率,并针对贫化因素给出相关指导建议降低贫化,使企业获得最大效益。
With the successive end of the thick and large ore deposits,the mine enters the stage of edge,far,narrow and poor mining.With the narrowing of the mining vein,the mining efficiency decreases and the mining cost increases.Based on the profit and loss balance point analysis method of the engineering economic principle,this paper analyzes the key factor dilution rate which affects the industrial ore quantity benefit in the narrow pulse mining,and gives the suggestion to reduce the dilution in view of the dilution factor,so that the enterprise can get the best benefit.
