摘要
为弥补现有数字矿床建模技术在地质矿产勘查处理和应用中的不足,从原始勘查数据建库及标准化、多指标单工程矿体自动圈定、基于语义识别的剖面矿体的连接与外推、矿体表面和品位建模、基于剖面矿体线框模型构建矿体表面模型及基于TIN+Octree数据结构和地质统计学理论建立矿体的空间属性模型等5个方面总结提出一套面向地质矿产勘查业务处理的矿床建模流程和总体技术解决方案.提高了地质矿产勘查研究精度,为进一步的矿山开采提供可靠的数据模型.
To make up the deficiencies of existing digital ore deposit modeling methods and its applications in mineral survey data managements,a method is advanced for ore deposit modeling in geological mineral survey data management.The method is featured with the following improvement：（1） Original mineral survey data standard informationization;（2） Automatic engineering orebody delineation by multi-confine and comlpex industry index;（3） Orebody joint and extrapolate mode in profile map based on semantic identification;（4） Orebody surface modeling by orebody wireframe model contours in profile map;（5） Orebody spatial attribute modeling by TIN＋Octree data structure and geostatistics,and its applications in mineral reserve estimation.So that it can enhance research precision on geological mineral survey and provide the credible orebody model for mining design.
