Zusammenfassung:	The method for drilling-round mine working with drill apparatus on wheel-rail chassis without restricting the range of the front of the working in which one changes the position of the drill apparatus with respect to the surface being drilled round through its discrete displacement, this is performed with stepping hydro-mechanical system with outriggers and jacks with hydro-cylinders of horizontal and vertical displacement, respectively, with use of power of the flow of high-pressure working liquid and with provision of stability of the unit with respect to overturn. Besides that, the high-pressure working liquid flow is divided to equal parts and supplied to connected in pairs hydro-cylinders of outriggers of horizontal displacement of drill apparatus.
