摘要
工业指标是矿床勘探、开发的依据,是矿床经济评价、矿山生产调节和取得最好经济效益的基本因素。因此,在地质勘探、矿山开发的各个阶段,最需选择最佳工业指标,以保证资源的合理开发利用。笔者通过湘西某矿山的各项技术经济指标的实施情况,按收支平衡法计算了金、锑、钨的最低工业品位,不但扩大了矿山保有储量,而且找出了生产管理上的弊病,从而保证了矿山最好的经济效益。
The commercial factors are basis for exploration and exploitation of mineral deposits, and are basic factors for economic evaluation of mineral deposits, adjustment of mining production and obtaining best economic benefit. Hence, in each stage of geologic exploration and mining exploitation it is always necessary to select the optimal commercial factors in order to ensure the comprehensive exploitation and utilization of mineral resources. Based on the practice of each commercial factor in a mine in western Hunan, the author calculated the minimum mining grades of gold, antimony and tungsten according to income-expenditure balancing method, which not only expanded the reserve's period of production, but also found out the deficit in the management of production so as to ensure the best economic benefit for the mine.
