铜厂矿区矿石体重测试

Volumetric Weight Determination of Ore in Tongchang Mining Area

德兴铜矿铜厂矿区从矿山生产以来先后进行过两次矿石体重测定工作,但随着铜厂矿区露天开采的深入,表土层和岩体上部风化氧化带逐步减少,采区内构造裂隙发育程度逐渐减弱,矿石的致密度提高,矿石的体重参数对采矿量计算造成一定的影响。因此对矿区矿石体重重新测定,并对体重与铜硫品位关系和区域分布规律进行初步研究。

The volumetric weight determination of ore has been carried on twice since production in Tongchang Mining Area of Dexing Copper Mine,but along with the deep-digging of the open pit in Tongchang Mining Area,topsoil layer,weathered zone and oxidized zone are reduced,geological structure fracture development to be lower and the density of ore are increased,the volumetric weight parameter of ore has certain influenced the mining gauge calculation.Therefore,the volumetric weight of ore is determined renewedly,preliminary study is conducted the relations of ore volumetric weight and the grade of copper and sulphur,and the regularities of area distribution.
