基于组合权-模糊数学的多金属矿区资源开发利用效率评价

以某多金属矿区为研究对象，从矿石利用情况、环境影响、开发投入和经济效益四方面入手，提出13项评价指标，建立了多金属矿区资源开发利用效率评价体系。使用组合权法合理得确定了各项指标权重，并结合模糊数学法对某多金属矿区资源开发利用效率进行了评价。结果表明，KS1的开发利用效率最优，KS2、KS3次之；矿区环境状况不容乐观；矿区内铁矿石开发利用效率较高，铌矿物等有用伴生组分开发利用效率低，但采取了有效的保护措施，为日后大规模开发利用提供了有利条件，评价结果反映了矿区真实开发状况，能够为多金属矿区资源开发保护提供依据。 

The Efficiency Evaluation on Exploitation and Utilization of Polymetallic Mineral Resources Based on Combination Weight and Fuzzy Mathematics

Taking a polymetallic mining area as the research object, thirteen evaluation indexes are put forward from four aspects of the mineral resources utilization, environmental impact, exploitation investment and economic benefits. Meanwhile, the efficiency evaluation system of exploitation and utilization of polymetallic mineral resources is established. The weight of each index is reasonably determined using the combination weight method, then the efficiency of exploitation and utilization of polymetallic mineral resource is further evaluated by the fuzzy mathematics method.The results show that the optimal efficiency of exploitation and utilization is KS1 followed by KS2 and KS3; the environment of mining area is terrible; the efficiency of exploitation and utilization of iron ore in mining area is higher than those of niobium minerals or other useful associated minerals; however, the effective measures provide favorable conditions for large-scale exploitation and utilization in future. The evaluation results reflect the real condition of mining area, which can provide a basis for the exploitation and protection of polymetallic mining area.
