Geophysical methods play a crucial role in mining waste management by providing valuable information about the subsurface characteristics of mining waste sites. One of the most used techniques is Electrical Resistivity Tomography (ERT). It is commonly used in mining waste management to assess the electrical resistivity of subsurface materials. The principle behind ERT is based on the statement that different materials have different electrical resistivity values. In the context of mining waste management, ERT can provide valuable information about the composition, structure, and potential contaminants within waste deposits. By imaging the variations in resistivity, ERT can reveal the internal structure of mining waste deposits, including layering and variations in material properties.
