【摘要】:桂中三水鋁礦床是我國唯一的大型三水鋁礦床,初步查明(333+334)鋁土礦資源量7.7億噸。本文介紹地質(zhì)統(tǒng)計(jì)學(xué)方法在桂中三水鋁土礦床勘查和資源量評價中的應(yīng)用,包括桂中三水鋁礦床典型礦區(qū)變異函數(shù)的計(jì)算和模型擬合;最優(yōu)變異函數(shù)模型的確定;利用變異函數(shù)變程確定最佳勘查工程間距的實(shí)例分析;利用地質(zhì)統(tǒng)計(jì)學(xué)方法進(jìn)行礦體邊界和資源量類別的自動化劃分以及資源量估算。
[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.
