The integrated surface DTH drilling rig is capable of drilling vertical and inclined holes, and is mainly used for drilling large-diameter blast holes and pre-splitting holes in large open-pit mines and rock excavation projects. The rig is powered by a Cummins diesel engine as its sole power source, simultaneously driving the screw compressor system and the hydraulic transmission system through dual-end output.
