【摘要】：桂中三水铝矿床是我国唯一的大型三水铝矿床,初步查明(333+334)铝土矿资源量7.7亿吨。本文介绍地质统计学方法在桂中三水铝土矿床勘查和资源量评价中的应用,包括桂中三水铝矿床典型矿区变异函数的计算和模型拟合;最优变异函数模型的确定;利用变异函数变程确定最佳勘查工程间距的实例分析;利用地质统计学方法进行矿体边界和资源量类别的自动化划分以及资源量估算。
[Abstract]:The three-hydrate aluminum deposit in central Guangxi is the only large-scale three-hydrate aluminum deposit in China. The resources of (3333-334) bauxite are found to be 770 million tons. This paper introduces the application of geostatistical method in the exploration and resource evaluation of Sanshui bauxite deposit in central Guangxi, including the calculation and model fitting of the variation function, the determination of the optimal variation function model, the calculation of the variation function of the typical mining area in the middle Guangxi Sanshui aluminum deposit and the determination of the optimal variation function model. An example analysis of determining the optimum exploration project spacing by using the variation function range and the automatic division and estimation of ore body boundary and resource quantity category by using geostatistics method are carried out.
