基于AutoCAD的露天煤矿三维地质建模

3D geological modeling of surface coal mine based on AutoCAD

露天煤矿三维地质模型的建立是矿山数字化的核心组成部分.三维地质模型的建立,对矿山的经济评价、采矿设计和生产管理都具有重要的指导意义.以具体露天煤矿为例,介绍了基于AutoCAD的三维地质建模技术,建立了该矿的三维地质模型并将其应用于工程实际,实现了该矿的三维地质模型建立和可视化显示,以及钻孔数据库的建立、模型的修改与实时动态更新、模拟开采等功能,使矿山工程技术人员在一个真三维环境中,利用三维可视化模拟开采技术,以"人机交互"的方式进行露天矿开采设计、生产计划编制等.

3D geological modeling of surface coal mine is a core component of Digital Mine. The establishment of 3D geological model provides decisions for the estimation and design of Open Pit Coal Mine, and the models have an important guiding significance during the mine＇ s production and provide more important information for the designers. This paper, by taking specific surface coal mine for example, introduces the technique of 3D geological modeling of surface coal mine based on AutoCAD, builds 3D 3D geological model, displays the 3D geological updates 3D geological model, simulation mining, geological modeling of the mine, applies it in engineering, establishes model in any direction, builds the drilling database, modifies and and so on. The establishment of 3D geological model enables mining engineers in a real three - dimensional environment and in the approach of ＂human - computer interaction＂, so as to realize the mining design and mining plan, and so on.
