针对湖北大冶矿区复杂的地质问题,基于高精度重磁实测数据,采用三维重磁数据概率分析和物性反演技术,实现了大冶矿区重磁资料的精细化处理与解释,为大冶危机矿山深部及外围找矿提供了重要的参考.在无约束条件下对高磁异常源进行了三维概率成像反演,并结合地质先验信息完成了矿区航磁异常的带地形人机交互三维反演,预测了矿区沉积岩类与闪长岩体接触带的空间延展形态,定量反演了矿区的三维物性特征,反演结果显示在矿区深部(1000m以下)及接触带弯折部位为有利的找矿区域,目前通过实钻已得到证实.
Aiming at the complicated geological problems in Daye Mining Area of Hubei Province, the precision magnetic and magnetism measured data are used to realize the meticulous processing and interpretation of heavy and magnetic data in Daye Mining Area by the probability analysis and physical inversion of 3D gravity and magnetic data, Which provides an important reference for ore prospecting in the deep and periphery of mine.Under the condition of unconstrained, the three-dimensional probabilistic imaging inversion of high magnetic anomaly sources is carried out and the three-dimensional The spatial extension of the contact zone between sedimentary rocks and diorite bodies in the mining area is forecasted, and the 3D physical properties of the mining area are quantitatively retrieved. The inversion results show that it is advantageous to find the deep part of the mining area (below 1000m) and the bending part of the contact zone The mine area has now been confirmed by real drilling.
