桃林铅锌矿尾砂库资源化综合利用评价

COMPREHENSIVE UTILIZATION OF THE TAILING BANK OF TAOLIN LEAD-ZINC MINE

为了掌握桃林铅锌矿尾砂库资源化综合利用状况,首先通过遥感解译,基于尾砂库筑建前与闭库后DEM数据查明了尾砂库的基本情况;其次,按照市场价格进行了潜在经济评价;最后,根据矿业遗迹与周边的自然、人文景观特点,进行了矿山公园评价。桃矿尾砂库的地表占地面积为2 214 726 m2,库容3 321.62×104m3,尾砂堆存量5082.08×104t。尾砂中有用金属镓的含量为12.34 g/t,储量627.13 t,潜在经济价值约4.54亿元;有用矿物萤石的平均含量为5.46%,储量277.48×104t,潜在经济价值约68.05亿元。评价结果表明,桃林铅锌矿具备申报国家矿山公园的基本条件与相关要求。

In order to evaluate the utilization status of the tailing bank of Taolin lead-zinc mine,the basic situation was analyzed by remote sensing interpretation and DEM data (before and after construction of the tailing bank).Then the potential commercial value of the tailing bank was assessed according to the market price.In the end,the mine park was evaluated based on the mining relics,surrounding natural landscape and human landscape.The research indicates that the area of Taolin lead-zinc mine is 2214726m^2,the storage capacity is 3 321.62×104m^3,and the tailing pile stock is 5082.08×10^4t.Among the tailings,the useful Gallium's contents is 12.34g/t and its reserves is 627.13t,which values about 454 million RMB.The average content of useful fluorite mineral is 5.46% and the reserves is 277.48× 10^4t,which values about 68050 million RMB.Thus,the Taolin lead-zinc mine satisfies the basic conditions and relative requirements of declaring a National Mine Park.
