This integrated DTH drilling rig is capable of drilling vertical, inclined, and horizontal holes, primarily used for drilling blasting holes and pre-splitting holes in large open-pit mines and rock engineering projects. Powered by a Caterpillar diesel engine, it drives both the screw compression system and hydraulic transmission system through dual output. The rig is equipped with an automatic rod handling system, a floating drill rod joint module, a drill rod lubrication module, an anti-jamming system, a hydraulic dry dust collection system, a climate-controlled cabin, and a drill angle and depth indicator
