面对固体矿资源的日益枯竭,开展第二深度(>500m)找矿迫在眉睫,大地电磁(MT)法勘探深度大,受高阻屏蔽小,在深部找矿中具有重要的地位。本文以某矿区实际地电模型为例,利用成都理工大学开发的MTSoft2D软件对其进行正演模拟和occam反演计算,探讨大地电磁法对地电模型中异常体的分辨能力,为MT法在深部矿产勘探领域提供理论支持。
In the face of the depletion of solid mineral resources, it is imminent to carry out prospecting at the second depth (> 500m). MT (Magnetotelluric (MT) prospecting is of great depth, is shielded by high resistance, and plays an important role in deep prospecting. In this paper, an actual electric model in a mining area is taken as an example, and MTSoft2D software developed by Chengdu University of Science and Technology is used to carry out forward modeling and occam inversion calculation to explore the resolving power of the abnormal body in the geoelectric model by the MT method. Provide theoretical support in the field of deep mineral exploration.
