中文摘要: 大明槽铜矿是位于元江铜矿带的“东川式”中型铜矿床之一。基于DIMINE软件平台,在建立矿床三维可视化模型的基础上,根据矿体实体模型、变异函数模型及品位模型揭示矿床矿化规律,并进行矿床经济评价研究,确定矿床Cu平均品位为0.68%。利用动态分析评价法,得出矿山未来生产能力为1 010 t/d,在对大明槽铜矿开发利用的经济分析中,市场价格对矿山企业收益影响最大,其次为产品产量。通过最优配矿方案的配合,大明槽铜矿具有良好的社会效益与经济效益。
Abstract:Damingcao Copper Deposit is a typical medium-sized deposit located in Yuanjiang copper ore belt. This paper establishes the three-dimensional visual model for Damingcao Copper Deposit by using DIMINE software. Then, the economic evaluation on the ore deposit is calculated, based on the established ore body solid model, variogram model and grade model. Besides, the average grade of 0.68% for the deposit is determined. In addition, this mining productivity of 1010 t/d is calculated by using dynamic analysis-evaluation method. According to the economic analysis of Damingcao Copper Deposit development, we conclude that the most sensitive factor is the price of the copper products, and the product output is the second. These results show that the Damingcao Copper Deposit could has good economic benefits and social benefits when combined with optimal scheme of ore bending.
