Study of Tunnel-Face to Borehole ERI (TBERI) Measurement Configurations and Its Optimization

Figure 7

Two-dimensional slice map of inversion model and result. The first column is schematic diagrams of three inversion models, which are the model of low-resistance block inside the target area, the model of low-resistance block outside the target area, and the model of double low-resistance block. The second column is the inversion results using the comprehensive set, and the third column is the inversion results using the optimized measurement configuration.
