青海祁漫塔格金属矿集区矿产资源开发优化布局分析

青海祁漫塔格金属矿集区具有丰富的矿产资源和广阔的成矿前景,是东昆仑成矿带最重要的铁多金属成矿远景区。为推动矿集区矿产资源的开发利用和可持续发展,从矿产资源条件、技术经济条件及环境影响3个方面,通过评价指标的筛选、指标权重与评价标准的确定以及评价指标的计算等构建了资源开发布局评价指标体系,并对祁漫塔格金属矿集区进行了矿产资源开发布局评价。评价分析结果为: 祁漫塔格矿集区11个开发区划单元综合评价平均值为7.0分,矿集区整体开发优势一般; 有2个开发区划单元综合评价值在8.0分以上,属于重点优先部署开发区域,分别为夏日哈木多金属矿区和虎头崖—迎庆沟多金属矿区; 有7个开发区划单元属于可以部署开发区域,可作为备选区域; 另有2个开发区划单元综合评价值低于6.0分,暂不宜考虑开发。

Analysis on optimizing layout of mineral resources development in Qimantag metal ore concentration area of Qinghai Province

Qimantag metal ore concentration area of Qinghai Province has rich mineral resources and broad metallogenic prospect and it is the most important iron polymetallic metallogenic prospective area in East Kunlun metallogenic belt. In order to promote the sustainable development and exploitation of mineral resources, the authors established the evaluation index system of mineral resource development layout from three aspects of mineral resources conditions, technical and economic conditions, and environmental impact. The system was constructed by means of evaluation index selection, index weight and evaluation criteria determination, and evaluation index calculation. Then, the mineral resource development layout in Qimantag metal ore concentration area was evaluated. The results of evaluation analysis show that the average value of the comprehensive evaluation of the eleven development units is 7.0, and the overall development advantages of the ore concentration area are general. There are two development units with a comprehensive evaluation value above 8.0 belonging to the key priority deployment and development areas, namely Xirihamu polymetallic mining area and Hutouya-Yingqinggou polymetallic mining area. Besides, seven development units are considered as alternative areas and two development units, with comprehensive evaluation value lower than 6.0, are not suitable for development at present.
