Abstract

Summary

Geophysical methods are extensively used to map geological structures like faults, folds, fractures, and dykes, which are key to understanding subsurface conditions and optimizing mining operations. These techniques are also effective in identifying geological hazards such as voids, cavities, and abandoned mine workings, providing essential information for mitigating ground instability risks and ensuring the safety of underground operations. This data is critical for mine planning and designing efficient mining layouts. Geophysical monitoring methods, such as Electrical Resistivity Tomography (ERT) are among the most employed techniques for identifying potential hazards and stability of underground structures. ERT is highly sensitive to changes in moisture levels and can detect zones with increased water saturation. In underground mining, excessive water infiltration can weaken rock formations and heighten the risk of flooding, slope instability, and subsidence. ERT surveys can identify groundwater infiltration zones and support proactive water management strategies.
