FIELD: electrical exploration.
SUBSTANCE: method of underground electrical exploration is to perform directional sounding point-to-point AM, N - ∞, B - ∞ or three-point AMN, B - ∞ installations of electrodes located in two workings one above the other. The supply electrode is grounded into the rock layerρ 0 on the wall in one working and U0 is recorded in it at the spacing. At the same time U is registered in another working. The apparent resistivity ρK of the upper and lower half-spaces is calculated.
EFFECT: possibility of studying the geological structure of the environment outside two workings.
