摘要
随着开采技术条件和市场环境的改变,很多工业指标之外的低品位矿石也具有了开采价值,惯常使用的矿产工业指标及其论证方法已不能满足现代矿业发展的需要。以西藏雄村铜矿的工程实践为例,阐述露天矿低品位矿石优化计算的一般过程,达到了合理开发低品位矿产资源及资源利用最大化的目的。
As the changes of mining technical condition and market environment, plenty of low-grade ores beyond industrial indexes have exploitatively valuable and frequently-used mineral industrial indexes and their means of demonstration can not meet the need of modern mining development any more. Taking the engineering practice of Xiongcun copper mine in Tibet for example, this paper represents the general process of optimization calculation for low-grade ores in open pit, which achieves good results of economic development of low-grade mineral resources and maximized utilization of resources.
