基于Surpac的矿山三维可视化地质模型的研究与应用

摘要

当今矿业已逐渐向着数字化、可视化的方向发展.矿山三维可视化地质建模是矿床的数字表征,是"数字矿山"的关键技术之一.本文应用澳大利亚SMG(Surpac Minex Group Pty Ltd)公司的Surpac大型矿山工程软件,构建了某铁矿的三维可视化地质模型.并采用距离幂次反比法和地质统计学方法,分别对块体模型进行了品位估值,以及利用块体模型进行了矿体储量计算.计算结果准确,为合理开发矿山资源提供了科学依据.%Today's mining industry is advancing gradually toward digital and visual direction. The three dimensional visualization geological modeling of mine is the digital characterization of mineral deposit and is one of the key technology of digital mine. This paper constructed the threedimensional geological modeling of an iron mine through the use of Surpac, and grade of the ore body were estimated respectively by using Distance Certain Power Inverse Method and Geostatistics, and reserve of the ore body were estimated. Its result is Accurate, so it provided scientific bases for reasonably developing resources of mines.
