Seeking for coal mining costs reduction is connected with a reduction of number of longwall faces with increasing of unit production at the same time. That can be achieved by increasing of machines output. Concept for supplying the integrated group of longwall machines with 6 kV voltages in geological and mining conditions of Knurów Colliery was presented in the paper.
