When solving problems of predicting the hazards of solid rock bump and outburst in development and stope workings, the resistivity probe methods are often used, in particular, the four-probe method, in which electrodes are placed on the roof or the sill of the mine. The presence of steel lining in the mine significantly affects the measurement results until the complete collapse of electric field, so the electrodes are embedded into the rock. To obtain the true value of rock resistivity, it is necessary to make corrections due to the metal lining influence. This paper is devoted to the determination of these correction factors.
