Axis 1 connecting the chassis undercarriage carrier with the portal frame 1, is located asymmetrically with respect to the axes of the wheels 3. At the ends of the rails 10 is installed lugs 11.The device operates as follows.As the destruction of the bottom hole using drilling equipment 6, the rock mass pick up buckets 7, which are fixed on the telescopic shafts 8 and loaded into the trolley 12, which is delivered directly to the pile of crushed rock mass through space portal frame 1. After the liberation of the face from crushed rock mass to the place of installation fasteners in the trolley take the lining elements and produce mount production using Krepostnaya 9. Then as progress unit forward with sinking produce produce moving temporary rail track, for which the frame 1 is lifted by means of outriggers 5 above the rails 10 and against the buckets 7 are installed on the rails lugs 11, the movement of the trolley with carrier portal frame 1, located asymmetrically with respect to the axes of the wheels 3, when the lifting frame 1 chassis 2 wheel 3 rotates under its own weight relative to the asymmetric axis 4 so that one of the wheels 3 is in constant engagement with the rail 10, covering the rail head with double-sided flanges of performing the functions of the guides, thus providing parallelism and alignment of rails 10 temporary path. The drilling UNIT, including mounted for movement along rails carrier frame with two running trucks with pairwise fixed in the housing of the wheels associated with the axle carrier frame, drilling equipment and a telescopic boom with a cargo body mounted on the carrier frame, characterized in that it is equipped with Krepostnaya placed on a frame, which is made portal and has outriggers, and the axis connecting the chassis undercarriage carrier with the portal frame, is located asymmetrically with respect to the axes of the wheels, and the ends of the rails located on the downhole side, set stops.
