The invention relates to the field of mining and can be used in the mine working.

Known tunneling 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.

The known device is not using the intermediate conveyor, that increases the energy intensity of loading and dusting, delivery of items lining to the chest along the bottom of the unit and installation is carried out manually. These units have limited scope and are dependent on angle of the output, have a large volume of mechanized skidding rails to move the excavating unit.

The purpose of the invention to reduce the energy intensity of loading and dust due to the loading of the rock mass directly into the trolley, the decline in the share of manual labor in the process of securing due mechanized delivery of items lining up to slaughter and installation Varnakov using Krepostnaya, as well as reducing the complexity of the shifting rails to move the excavating unit.

The purpose of the invention is achieved due to the fact that the drilling unit is equipped with Krepostnaya placed on a frame, which is made portal and has outriggers, the axis connecting the chassis undercarriage carrier with the portal frame, is located asymmetrically with respect to the axes of the wheels. At the ends of the rails located on the downhole side, set the stops.

In Fig. 1 shows the tunneling unit, General view; n is AMI, having pairwise fixed in the housing 2, wheels 3, associated axis 4 with the carrier frame 1, the outriggers 5, drilling equipment 6, loaders coupled bodies, such as buckets 7, which are fixed on the telescopic shafts 8 and Krepostnoy 9. 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.
