摘要

摘要:
矿产资源勘查的目的是系统地了解矿产资源的赋存情况, 以进一步支持资源评价和生产.在这一过程中, 数据的分析与处理可以全面借助信息技术来提高其效率与质量.通过分析矿产资源勘查信息处理过程和当前发展现状, 认为可以通过数据管理、三维可视化和虚拟现实这3个环节对矿产资源勘查信息处理的全程进行系统集成, 并就其中的关键问题进行比较详细的分析, 提出了一种新的三维数据组织方式和一种基于上述3个环节的系统表达地质实体的新方法, 并应用于多项勘查工作中, 取得了良好的效果.

Abstract:
Mineral resource prospecting aims at providing sufficient information on mine state for further resource evaluation and production.In this process, the information technique can be utilized to increase the efficiency and quality of data analysis and processing.In this paper, the authors consider that data management and three dimensional model and virtual reality are three pivotal taches of information processing, by which we can systematically integrate the information technique for mineral resource prospecting.And the authors put forward a new 3D data structure and a new systematic method for expressing geological solid, which have already been successfully applied to multi-resource perambulation work.
