THE RIG PROVIDES DRILLING OF THE FRONT SLOTS IN OPENINGS WITH A SECTION OF 6 . . . 12 M2, AS WELL AS DRILLING FLANGE (SIDE) BOREHOLES AT AN ANGLE OF UP TO 120 DEGREES FROM THE LONGITUDINAL AXIS OF THE INSTALLATION AND DRILLING A DRILLING DRILL OF 3.5 M.
Drilling rig UBSH - 221P on a pneumatic undercarriage is designed for drilling boreholes when passing horizontal mine workings in rocks with a strength factor of f = 8 . . . 20 on the scale of MM Protodyakonov.
The installation provides drilling of front faces in workings with a cross section of 6 . . . 12 m2, as well as drilling of flank (side) boreholes at an angle of up to 120 degrees from the longitudinal axis of the installation and drilling of boreholes into the roof at a height of more than 3.5 m.
The rig is produced in two versions: B106.00.000 - 01 - for drilling bore - holes in ordinary mines with a positive temperature; B106.00.000 - 02 (northern version) - for drilling bore - holes when passing through permafrost placers by underground method.
The installation can be used for drilling boreholes when excavating various chambers up to 3.5 m high. The installation operates on compressed air with a pressure of 0.5 MPa (5 kgf / cm2), air is supplied from the mine main by two sleeves. Compressed air drives the oil pumping station when pointing the drilling machine to the point of drilling, feeding the drilling machine to the bottom hole, drilling, drive of the undercarriage, drive of lighting. The unit is controlled by pneumatic and hydraulic consoles.
The use of on - board drives of the bogie provides high cross - country ability and maneuverability.
Autonomous lighting installed on the drilling rig provides the necessary illumination of the bottomhole and does not require laying of an electric cable.
Drill rods of circular section with a diameter of 32 mm or a hexagonal section of 25 mm, with a shank for a drilling machine and drill bits with a diameter of 40 . . . 52 mm are used as drilling tools.
