矿产资源可供性动态分析的一种方法——试论储量品位与成本价格关系及其模型编制

DYNAMIC ANALYSIS OF MINERAL RESOURCES SUPPLY

在市场经济条件下矿产已商品化,使其储量、品位与成本、价格四要素之间的关系呈现相关互动。即这4个要素中的某一个发生变化时,将牵涉其他3个要素的变化。据此编制储量、品位与成本、价格关系模型,显现在开发矿产资源过程中,品位、储量具有动态形式,并随着价格与成本升降而变化。因此运用这种模型,根据矿产品的价格变化可简便、快速、直观地调整开采成本,确定盈亏品位界限、成本与价格比和储量可供情况。模型还可为政府部门或大型企业集团实施储量、品位动态管理,使矿山企业科学配矿,贫富兼采,提高资源利用率,保护利用好矿产资源。

Mineral resources is one kind of merchandise in the market economic system. The system leads to such a situation that reserve, grade, cost and price are related with others, and others will change at the same time as one change. A dynamic tnodel describing relationship among reserve, grade, cost and price has been designed. The model shows that reserve and grade change dynamically with price and cost in the course of developing mineral resources. According to this model, it is easy to make adjusting the mining cost and determining the cutoff grade, ratio of the cost with price and as well as the situation of minable reserve based on the price variation of mineral products. This will assist the government and firms to manage dynamically mineral reserve and grade, and also make for the reasonable mining and ores partitioning and increasing utilizing ratio of mineral resources.
