JGZ-1220 DRILLING RIG
This drilling machine is mechanical and hydraulic drive which rotated and transmit very smooth, it has low center of gravity. The compact structure and reasonable layout make it convenient to transport. The opening diameter of rotary table is large and the borehole diameter is below 1200 mm. It does not need to use the overhead drilling platform and the trailer.
Mainly used for mine emergency rescue drilling, the pre-built exit well from ground directly goes to the Refuge Chamber, and the mine ventilation well and the goaf filling well drilling project. It can also be used for the other large diameter drilling project.
