Technology of Three-dimensional Visualized Solid Modeling for Mineral Deposit with Complicated Geological Structure

复杂地质构造矿床实体建模的关键技术,是如何将地质和采矿工程师的经验充分和有效地考虑进来,建立全面反映地质构造的“真实”矿床模型,为块段建模、品位估值、储量计算、生产计划编制提供基础。在讨论了地质实体建模理论的基础上,采用M icrom ine矿业工程软件对实际矿山进行三维建模实践研究分析,介绍了如何建立复杂地质构造矿床三维可视化模型。结果表明,目前已经具备了建立复杂地质构造矿床的基本技术,正确合理采用三维建模工具并将地质采矿工程经验考虑进来,可以建立合理有效的复杂矿床模型。

The key technique of deposit solid modeling of complicated geologic structure is how to fully and effectively take into consideration the experiences of geological and mining enginers in building up a ＂true＂ model of mineral deposit that can fully reflect the geological structure so as to lay a foundation for block modeling, grade evaluation, reserve calculation and production scheduling. Based on the discussion of geological solid modeling theory, study was carried out on the three-dimensional modeling practice for a real mine by MICROMINE, a mining engineering software, and description was made about how to build up a three-dimensional visualized model for the mineral deposit with complicated geological structure. The results show that the basic technique of modeling complicated architectonic deposit has been grasped. With the three-dimensional modeling tool correctly and reasonably adopted and the experiences in the geological and mining activities taken into consideration, a reasonable and effective model for complicated deposit can now be constructed.
