“Kaishan” KT7C integrated surface DTH drilling rig is advanced drilling equipment integrating down-the-hole drilling system and screw air compressor system. It is of compact structure, well integrated and easy to move and its two systems are powered by a diesel engine with six cylinders.

Its high air pressure screw compressor head with core intellectual product and single stage compression adopts internationally advanced Tangshi Y-line to produce high flow (13m³/min) and high air pressure (1.7MPa), thus it provides strong power for high pressure pneumatic hammer and its drilling speed is 20%-50% higher than that of medium Working pressure drilling rig.
