基于三维信息技术大比例尺三维立体矿产预测方法及途径

大比例尺成矿预测是矿田发现深部隐伏矿床的重要途径。随着三维地质信息技术的日臻完善,研究和开发三维可视化环境下地质勘查数据处理与信息综合方法十分必要。以我国甲玛等十几个矿山三维建模预测工作为支撑,初步研究了矿田控矿构造三维模拟、矿床模型三维可视化、三维信息综合定量预测等关键技术问题,探讨了三维预测软件开发技术难点,总结了大比例尺三维预测工作流程,并用实例说明应用成效。

Largc scale 3D mineral prediction methods and channels based on 3D information technology

Large scale metallogenic prediction methods were important for the exploration of deep hidden deposits in ore field. It was a very necessary measurement for research and development of the treatment and information synthesized of the geological explorative data, under the condition of 3D visualization, as improving 3D geological information technology. According to 3D modeling predictions of Jiama Mine and other ore deposits, the authors briefly studied some key technologies i.e. 3D simulation of ore-control structure in ore field, 3D visualization of deposit model and 3D information synthesized quantitative evaluation, and discussed that the technical difficulties of 3D prediction software exploitation, working course of large scale 3D prediction and application effect by using examples.
