This paper presents and discusses the results of theoretical approach of the BPL (Broadband over Power Line: 2 MHz–32 MHz) transmission efficiency in 6 kV cable line of selected underground mine. The research verifies its validity through practical measurements. It is followed by the derivation of the power line parameters using the transmission line theory. The tests under the mine conditions were carried out for a specific 6 kV mine cable, with steel armour, for as inductive as well as capacitive coupling of BPL modems with the MV grid. The obtained results are not found so far in the literature and constitute the innovation of the achievement. On the basis of the results the conclusions for practical applications have been formulated.
