The paper describes estimation of the energy parameters of electromagnetic communication channel through rock for staff safety and emergency response in the mines. The optimum frequencies of radio waves in depend on the conductivity of the rock and the distance ranges are determined. The minimizing of the transmitting power at the limited antenna size and electromagnetic mine noise is considered.
