الملخص:Trial excavation road head in the lignite seam was carried out by the application of semimechanized operation with coal seam undercutting. After 6 months of trial work no production effects were attained, so the trial mining field was liquidated and any further trials were given up. The experiences from the first road head work in concrete and complex mining conditions are considerable. They indicate the possibility of application of the complex mechanization with the lightest equipment if its price and the coal competitiveness will allow and adjust it (the paper is published in Croatian).
