– The final result of the project is to create a 2D model mine plan based on results geophysical measurements. ERT was chosen as primary method in this due fact that voids and air have very high resistivity (3,3 ∙ 1016Ωm). Voids are well recognizable results. Using Seismic Refraction Tomography (SRT) planned some profiles. SRT rarely used archaeogeophysical research.
