KAISHAN KT7H integrated open-pit DTH drill rig is a new-generation all-in-one drilling solution independently developed for medium and large open-pit mines and quarry engineering. Different from split drilling equipment, this rig integrates a high-performance two-stage screw air compressor and professional DTH drilling system into one unit, eliminating the need for external air compressors and pipelines, realizing convenient movement and one-stop drilling operation.
Powered by a 195KW high-quality Yuchai diesel engine and matched with a 18bar high-pressure air compression system, the equipment provides stable and powerful air supply and impact force. Adopting dual rotary motor configuration, it achieves high torque and high-speed rotation, effectively improving penetration speed in hard rock formations, with drilling efficiency 20%-50% higher than ordinary medium-pressure drill rigs.
Equipped with an automatic rod handling system and professional drill rod lubrication module, KT7H minimizes manual operation, reduces labor costs and avoids operational errors. The reinforced high-strength aluminum alloy feeding beam ensures structural stability during long-term high-intensity operation. The built-in high-efficiency dust removal system effectively suppresses construction dust, meeting green mining environmental requirements.
With a heavy-duty crawler walking structure, maximum 25° climbing capacity and excellent terrain adaptability, the rig can stably operate on rugged mountain slopes and complex construction sites. It supports vertical, inclined and horizontal drilling, widely used in open-pit mine blasting holes, quarry pre-split holes, road foundation and infrastructure rock drilling projects. Featuring low maintenance cost and outstanding comprehensive performance, KAISHAN KT7H is a cost-effective integrated drilling equipment for global mining contractors.
