Kaishan DTH Drilling Rigs
Heavy-duty surface crawlers and integrated rigs for open-pit mining, quarry blasting, and slope stabilization. High penetration rate and anti-jamming hydraulic system.
EQUIPMENT CATEGORIES
Utilizes dual-wall hollow drill pipes where high-pressure air enters through the outer annulus and flushes high-purity ore samples directly up the inner tube. This completely prevents cross-contamination, ensuring precise stratum and grade identification to optimize blasting layouts and ore recovery per ton.
Powered by a heavy-duty Cummins QSZ13-C500-30 diesel engine (372 kW) driving an onboard Kaishan SKY11HG220-A two-stage screw compressor (31 m³/min at 25 bar) and hydraulic pumps (1 plunger + 1 triplex gear pump), delivering 6100 N·m torque and 65 kN hoisting force for RC4 to RC6 hammers.
Features an 8+1 automatic rod changer handling Φ102/Φ114×6000 mm pipes for 54 m deep exploration, automatic oil-spray lubrication, floating joint thread protection, electro-hydraulic anti-jamming, and a certified FOPS & ROPS safety cab with -30°C to +45°C ambient climate capability.

The Kaishan KD65RC reverse circulation exploration drilling rig is engineered specifically for mining geology, ore body delineation, and rapid grade control operations:
In standard DTH drilling, cuttings travel up the outside of the pipe against open borehole walls, causing sample loss and contamination. The KD65RC uses dual-wall pipes where compressed air travels down the outer tube, and high-velocity air carries cuttings directly up the isolated center tube into an onboard cyclonic sample collector, guaranteeing 100% representative geochemical samples.
The KD65RC is equipped to operate RC4, RC4.5, RC5, RC5.5, and RC6 reverse circulation DTH hammers with an 8+1 automatic carousel storing Φ102 or Φ114 × 6000 mm dual-wall drill pipes (6700 mm feed stroke), delivering up to 54 m depth.
As an authorized China manufacturer and global B2B supplier, we provide factory-direct pricing, flexible MOQ, OEM/ODM customization, sample cyclone splitters, and complete RC drilling consumable packages (RC hammers, dual-wall pipes, inner tubes, and seal kits).
