新疆乌拉根铅锌矿开发技术经济评价

塔西地区乌拉根铅锌矿床位于新疆乌恰县康苏镇南东5 km,是近年来新建成的超大型砂砾岩型铅锌矿床,是塔里木盆地西缘与盆山演化和盆地流体演化有关的典型砂砾岩型铅锌矿床,该类型矿床在成矿机制、成矿规律、找矿勘查和开发利用等方面受到了学术界、勘查界和矿业界的广泛关注。塔西地区已成为砂砾岩型金属矿床的基础理论研究的热点,同时也成为铜、铅、锌等金属矿产勘查的最为活跃的地区之一,发现了一批包括乌拉根超大型砂砾岩型铅锌矿床在内的具有工业意义的铜铅锌矿床(点),显示出塔西坳陷区具有极大的砂砾岩型铅锌矿床的找矿潜力。文章以乌拉根超大型铅锌矿床为模型,开展该类型矿床的资源量—经济评价,运用不确定性分析计算出盈亏平衡率和盈亏平衡点,并进行了敏感性分析,对区内同类型矿山的工业开发利用和投资决策具有一定的参考意义。

Economic and technical evaluation of Wulagen lead and zinc ore deposit in Wuqia, Xinjiang

The Pb-Zn mine bed in Taxi area is located in the South East 5km of Kang Su Town, Wuqia County, Xinjiang, and is a typical sandstone-type lead-zinc deposit related to the evolution of the western margin and basin of the Tarim Basin and the fluid evolution of the basin, which is the metallogenic mechanism, metallogenic law and Prospecting, exploration and exploitation have been widely concerned by the academic, exploration and mining circles, not only making the Ta-Xi area become the focus of the basic theory research of gravel type metal deposits, but also becoming one of the most active areas of copper, lead, zinc and other metal mineral exploration, A number of industrial significance copper-lead and zinc deposits (points), including the super large gravel type lead-zinc deposit of Ura root, were found, which showed that the prospecting potential of the depression area of the west of the tower was great.Taking the large lead-zinc deposit of URA root as the model, this paper carries on the resource quantity-economic evaluation of this type of deposit, calculates the break-even rate and the break-even point by using uncertainty analysis, and carries on the sensitivity analysis, which has the important reference significance to the industrial development and utilization and investment decision of the same type mine in the region.
