摘要
为了掌握我国铜矿资源的经济可供性,本文针对我国铜矿资源及其开发利用状况,建立了我国铜矿资源可供性分析模型;利用可供性评价软件系统对我国铜矿资源进行了可供性分析,表明我国317个未利用铜矿区中有49个矿区的资源储量是可供的,具有可供资源储量的未利用铜矿规模较大,开发经济效益一般;具有不可供资源储量的未利用铜矿大多规模较小,开发利用的经济效益很差。品位一吨位曲线反映出我国铜矿品位偏低,铜矿品位超过1.25%的基础储量和资源储量均非常少。采用成本一吨位曲线表达了我国铜矿资源在不同成本条件下铜矿的可供资源储量。
This paper,aiming at the availability of copper resources in China,based on the copper resources and their development,establishes a mode,and applies a software system to analyze the availability,with the results showing that 49 copper mining districts out of 317 unmined copper districts can be mined,with big sizes but low economic benefits.Those that can not be mined are small sized with poor economic benefits.The grade-ton curve reflects a low grade in copper ores in China.The basic resources and reserve over 1.25% grade is quite limited.The cost-ton curve displays the available copper resources under different cost conditions in China.
