综合地球物理方法在隐伏断层探测中的技术优势

The Technical Advantage of Integrated Geophysical Methods in Blind Fault Exploration

针对攀枝花马家田尾矿坝周边山体的地质及地球物理特征,综合采用浅层地震法、高密度电法、重力法以及氡气测量对工区内的隐伏断层进行详细探测,并着重对物探资料进行综合解释。结果表明,采用合适的综合方法,可在一定程度上减小物探反演的多解性,提高物探成果的可信度。

Aiming at the geological and geophysical characteristics of surrounding massif around Majiatian tailing dam in Panzhihua, the blind faults in the site are explored in detail by using the shallow seismic method, the high density resistivity method, gravitational method and radon survey, and the geophysical data is emphatically explained. The result shows that an appropriate complex method could help to reduce the multi-solutions of inversion to a certain extent and increase the reli- ability of the geophysical prospecting.
