摘要
三维地质建模及可视化技术的发展为复杂矿床的找矿工作提供了新的机遇与挑战,通过构建地质体三维模型,使得地质矿产勘查开发工作更为便利。本文以姚家岭锌金多金属矿床为研究对象,运用当前国际上比较流行的地统计学方法展开研究。利用地统计学方法对样品数据进行分析并插值生成姚家岭锌金多金属矿床的三维块体模型,由此分析该矿床的空间地质体形态特征及品位的空间分布规律,对原始钻孔数据进行分析并内插生成姚家岭的三维块体模型以及勘探线剖面图,结果表明,这些三维块体模型的空间形态特征、品位分布特征以及剖面图所呈现的矿体特征都与实际较为符合。因此,本文所采用的方法为矿产勘查工作提供了新思路,对地质工作者的圈矿工作也有一定的指导意义。
The development of three-dimensional geological modeling and visualization technology has provided new opportunities and challenges for prospecting of complex ore deposits. By three-dimensional modeling, geological and mineral exploration and development work is made more convenient. Taking the Yaojialing zinc-gold polymetallic deposit as the research object, the world-popular geostatistical method was used to analyze the sample data and interpolate thus generating a three-dimensional block model to understand the morphological features of geological bodies of the deposit and spatial distribution regularity of the ore grade. The original borehole data were analyzed and interpolated to generate the three-dimensional block model and exploration line profile of the Yaojialing deposit. The results show that the spatial morphological characteristics,grade distribution characteristics and ore body characteristics of these three-dimensional block models are in good agreement with the reality. Therefore, the method adopted in this paper opens up a new way of thinking for mineral exploration and plays a certain guiding role in delimiting an ore deposit.
