KT9D Integrated Surface DTH Drilling Rig
Inquiry

The integrated surface DTH drilling rig is an advanced drilling rig that integrates the DTH drilling system with a screw-type air compressor system. It is capable of drilling vertical, inclined, and horizontal holes, and is primarily used for blasting and pre-splitting operations in open-pit mining and rock excavation projects. The rig is powered by a Yuchai non-road diesel engine, which simultaneously drives the screw compressor system and the hydraulic transmission system.

The rig is equipped with an automatic rod handling system, a drill rod lubrication system, and a hydraulic dry-type dust collection system. It features strong structural integration, a high level of automation, efficient drilling performance, environmental protection, energy efficiency, convenient operation, high mobility, and safe operation.
