| [摘要]运用地质统计学的方法对普朗矿区铜品位分布情况进行了研究,建立了铜品位变异规律
的数学模型,分别得到了矿体厚度、倾向和走向3 个方向的变异函数,该函数呈几何异向性,比值为1:
1郾612:3郾869,反映出矿体铜品位在3 个方向上的相关性较好,说明铜品位分布总体变化系数不大,有利
于矿山的开采。统计得出铜品位属于正态分布,表明下一步用普通克立格法进行估值效果最好,为矿山
规划设计和生产提供了理论依据。 |

| Abstract: In this paper, the use of geostatistics methods to PuLang copper Mining. on the copper grade distribution of the study. Set up a copper grade of
variation of the mathematical model. Weighted polynomial regression method to achieve automatic fitting the experimental variogram. By cross鄄validation. Selection
of the ideal experimental variogram parameter values. Ore bodies have been the direction of thickness, dip and strike copper grade variogram. The function was the
geometric anisotropy. Ratio of 1:1.612:3.869. Reflect the grade of copper ore body at the direction of three on the relevance of good. Note the overall copper grade
distribution coefficient is not Change. Conducive to the exploitation of mines. In addition, a copper grade of statistics belong to the normal distribution model. In
other words. Next by Ordinary Kriging for the valuation of the best. The copper grade distribution of the mathematical model for the future to find similar PuLang
Indosinian porphyry copper must have played a guiding role. For mine planning and design and production provides a theoretical basis. |
