井下矿山经济可采矿块评价探讨——以东乡铜矿东区为例

EVALUATION OF UNDERGROUND MINABLE ORE BLOCK IN MINE ECONOMY ——TAKING THE EASTERN DONGXIANG COPPER MINE AS AN EXAMPLE

东乡铜矿采用边际效益原理、级差矿利法和计算机手段，根据铜资源的供求状况、产品价格、工程进展和经营管理水平等的变化，动态地评价每个矿块的经济可采性，从而达到合理开采矿块，提高矿山经济效益，以适应市场经济。

By use of the principle in edge effect,ore interest method in grade differentiation and computer method,the economic minability of each ore block has been dynamically evaluated based upon the supply and demand situation of copper resources,price of the product ,engineering progress and level of management and administration,which makes to be able to mine the ore block reseanablly, to improve economic benefit of the mine and to adapt market economy.
