摘要: 以西藏驱龙铜矿为例,论述地质统计学方法在大型露天矿山资源估算中的应用,通过分析铜钼品位的统计分布特征,选取铜钼为区域化变量,进行变异函数计算及结构分析,建立矿床数学模型,进行品位估值和资源量估算;在此基础上确定开采境界优化参数,并根据所建立的矿床数学模型,在MineSight软件中用L-G 法对开采境界进行优化,取得了较好的优化效果,实现资源的最优化利用和可持续发展之目的。

Abstract: Taking the Tibet Qulong Copper Mine for example,the application of geo-statistics method in the resource evaluation of large-scale open-pit mine is demonstrated,and the copper-molybdenum was selected as the regionalized variable to conduct variogram calculation and structural analysis and to establish deposit mathematical model for grade estimation and resource evaluation by analyzing the statistical distribution characteristics of copper-molybdenum grade. On this basis,the cutting boundary optimized parameters were determined to optimize cutting boundary according to the established mathematical L-G model in MineSight software method. A optimization effect was achieved for realizing the most optimal resources utilization and sustainable development.
