摘要
介绍红透山铜矿外围隐伏矿体三维定量预测的技术组合和方法体系。首先,借助三维可视化仿真环境,实现红透山铜矿的地表面、矿体、断层、地层实体模型的三维可视化。其次,将成矿信息场、地层形态场、断裂影响场、地球物理场等多元地学空间数据在统一的三维空间数据场构架下有效集成,实现了三维空间信息的综合研究和地学多专业的有机结合。其次,基于三维地质空间相关场分析,为三维定量预测提取定量指标集和建立预测模型。最后,使用三维定量预测模型对红透山矿外围的矿化位置与分布规律进行预测和评价,圈定找矿靶区。三维地质建模与可视化及三维地质空间相关场等技术的使用,为进行红透山矿外围隐伏矿体在三维空间中的分布及形态的定量预测提供支撑。
The systematic techniques and methods of concealed ore-body 3D quantitative prediction in the surrounding areas of Hongtoushan copper deposit of Liaoning province were introduced. Firstly, the 3D geological entity model of Hongtoushan copper deposit, including the terrain surface, ore-body, strata, and fault surface, was built in the 3D visualization circumstance. Secondly, through the integration of fields of mineralization information, strata＇s morphology, fault influence and geophysical attributes in the framework of 3D geological space, the comprehensive analysis of multiple disciplinary of geosciences was achieved. Thirdly, based on 3D geological correlation field analysis, a set of geological ore-controlling quantitative factors and the 3D quantitative prediction model were proposed. Finally, the 3D location and distribution of concealed ore-body in the surrounding areas of Hongtoushan copper deposit were predicted to delineate the target regions. The technology of 3D geological modeling, visualization, correlation field supports the 3D quantitative prediction of concealed ore-body.
