    • Utility model of the structure of the roadheader ripping head employed for driving headings in underground mining. The ripping head (1) has a tight chamber (11) with inlet (15) and outlet (16) terminals for the cooling agent fixed to the external surface (10) of the frontal end (9), and both the inlet (15) and outlet (16) terminals as well as the ducts (23, 24) routed to them, feeding and discharging the cooling agent, are located in the upper longitudinal conduit (22) of the body (2) closed from the above with a detachable lid (25). The interior of the chamber (11) is beneficially divided with partitions (19), essentially parallel to the side plates (18) equipped with interchangeably distributed ports (20) directing the labyrinth-like flow of the cooling agent.
