摘要:

资源储量估算一般在特定的品位域内进行,其核心是确定采用哪些已知数据对未知点进行估值。传统方法在确定样品数据的特异值时,过多考虑矿床的经济性而忽略了其地质特征和品位统计特征。在勘查数据分析基础上,引入分形分析、边界分析和变异函数分析,以确定资源储量估算的品位域及相关参数。案例分析表明,改进的IDW法估值流程深化了样品数据的地质特征、品位统计特征和经济属性之间的联系,融合了不同估值技术方法特点,为传统资源储量估算提供了新思路。

Abstract:

Mineral resource and reserve estimation is generally carried out in a specific grade domain,and the essential issues are to determine which known data should be used to estimate unknown points.When fixing the extreme value of sample data,the traditional method takes too much consideration of the economics of the deposit and neglects its geological and statistical characteristics.Based on the exploration data analysis,this paper introduces fractal analysis,boundary analysis and variogram analysis to determine the estimated grade domain and related parameters of mineral resource and reserve estimation.Case study shows that the improved IDW estimation flowsheet has deepened the relationship among the geological characteristics,grade statistical features and economic properties of the sample data.Furthermore,the integration of different techniques and methods provides new ideas for the traditional mineral resource and reserve estimation.
