Undersurface core drilling machine is intended for drilling of prospecting wells (with preservation of the interior of rock in the form of a core- sample) and technological shot- holes and wells (solid face) up to 50 m in depth in underground mine workings which are dangerous because of gas (methane) and dust contents.
Drilling is possible, both with air blowing from the installed compressor, and from a hook-on compressor set, and also with washing from the hook-on pump station.
The manipulator of the machine allows to make a circular drilling in the section of mine workings with a minimum height of 2,4 m, and also a drilling in a face.
Small overall dimensions and the maneuverability of the machine allow to carry out works in the mine workings passed by mining combines Ural-10R (S=9,4 m2) and Ural-61A (S=8 m2).
Movement of the machine on mine workings and execution of works for drilling is carried out as in the independent mode (from the diesel drive), and with a power supply from the mine power supply network.
On the request of the customer, the machine can be completed with a hand hydraulic and pneumatic tool (chainsaw, hammer drill, air- hammer, power wrench, etc.).
