The Roadheader VT-100 is a self-propelled rock cutting machine for driving galleries (headings, tunnels). The roadheader can be operated in underground headings of mining facilities, also excavating hard coal, including headings with “a”, “b” or “c” methane explosion hazard degree and class A and B coal dust explosion hazard. The roadheader enables driving a heading of any shape and width (operation under several settings), over a height range from the loading table level to the maximum range of the cutting drum (i.e. approx. 4,3m from one setting). It is also possible to drive higher galleries when applying appropriate technologies, compliant with the mining art and regulations.

The Roadheader is adapted for operation in gas explosive areas, mainly in hard coal mines, while it can also be operated in mining of other mineral raw materials (e.g. halite), provided that the conditions of use specified in this manual are satisfied.
