The KH950 split type DTH drilling rig is a high-efficiency mining drilling machine equipped with an automatic rod changing system, designed for open-pit mining, quarrying, and rock blasting operations. It combines strong drilling performance with improved automation, making it suitable for medium-to-large scale drilling projects.
Powered by a Yuchai YC4DK120 diesel engine (Yuchai), the KH950 delivers stable output with 88kW rated power, ensuring reliable performance in continuous drilling conditions.
The machine supports a hole range of Φ115–138mm and is equipped with a 3" / 4" DTH hammer system, providing flexible adaptability for different rock formations. Its hydraulic feed system ensures smooth drilling with stable lifting and pushing force.
With an automatic rod changing system, the KH950 significantly reduces manual labor, improves drilling efficiency, and increases overall productivity, making it ideal for high-demand mining operations.
As a split type DTH rig, it does not include a built-in air compressor, allowing flexible matching with external air supply systems according to project requirements.
