“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.

• Integrating the down the hole drilling system and screw air compressor system, It is capable of drilling vertical, inclined and horizontal holes, mainly used for open-pit mine, stonework blast holes and pre-splitting holes; 

• Equipped with the Yuchai Engine and efficient dust collection system, the drill rig meets national standards for emissions and environment; 

• It is typical of energy conservation, efficiency, safety, environment-friendliness, flexibility, simple operation and stable performance, etc.
