陕西千家坪钒矿矿石贫化的主要因素浅析

An Analysis of the Main Factors of Dying Vanadium Ore in Qianjiaping Mine of Shaanxi Province

千家坪钒矿只有一条矿,长7.8 km,厚度1.54～48.50 m,平均10.16～14.35 m,这在金属矿产勘查中都比较少见。对控矿工程进行了统计,50%以上的工程都见到2～4层矿,全部采用推断、推测的分枝复合法圈连成一个矿体。实际开采中多数采场都遇到的是多条矿体,有的是夹石太窄无法剔除,有的是矿体太薄无法开采,更多的是矿体及部分夹石一起开采,无形中导致了矿石的贫化。

Qianjiaping vanadium mine has only one mine, which is 7.8 km long and has a thickness of 1.54 to 48.50 m, with an average thickness of 10.16 to 14.35 m, which is relatively rare in the exploration of metal minerals. The ore control project was counted. More than 50 % of the projects saw 2 to 4 layers of ore, and all of them used the inferred and inferred branching complex method to form a ore body. In the actual mining, most mining sites encounter multiple orebodies. Some of them are too narrow to be removed. Some of them are too thin to be mined. More of them are mined together with some of the orebodies and some of the orebodies, virtually lead to ore dilution.
