    Formations of cohesive rocks, which are hardly mined with use of actually used bucket-wheel excavators are often found during blanket mining in brown coal mines. A new solution of the cutting system moved on caterpillar chassis allowing mining of such rocks has been described in this study. Construction and principle of operation of such cutting unit, as well as preliminary results of the machine operation have been described for conditions met during floor mining in underground mines.
