摘要
针对传统方法资源储量动态估算存在的可视化及分析程度低、估算精度有待提高等问题,以矿山日常勘探与开发工作流程为主线,运用三维可视化技术对传统资源储量估算实现方式、方法进行改造,借助真实的三维地质几何模型取代抽象的规则几何体,研究并实现了一种新的适合中国资源勘查及储量分类特点的资源储量三维可视化动态估算及分析方法,可使传统资源储量估算方法科学、可视地贯穿于矿山勘探与开采整个工作流程。经实际矿山应用对比表明:矿体动用储量估算结果较大程度上受矿体块段及采空区空间位置、形态及厚度分布影响,基于勘探工程实际空间位置构建三维矿体块段及采空区模型进行资源储量动态估算与核减可有效提高传统方法资源储量动态估算的科学性与估算精度。
A new method for traditional mineral resource visualized dynamic estimation in 3D geological space is proposed,which is adaptive to the characteristics of resource exploitation and reserve classification in China.The method follows the daily workflow of mine exploitation,improves the traditional method for resource estimation by 3D visualization technologies,and replaces Abstract regular geometries with real 3D geological models.Thus,the traditional method for resource estimation realizes visualization in the whole workflow of mine exploitation.The application results to some real mines show the estimation results are mainly affected by the spatial location,shape and thickness of mineral blocks and goaf.If the resource dynamic estimation is carried out by constructing 3D mineral models in consistent with real exploitation project,the accuracy of the traditional method can be effectively improved.
