Mining Blast Hole Drilling Rig YQD-165

Product Advantage

Integrated Design for Efficient Large-Scale Operations

The whole machine integrates power, air compressor and drilling systems, eliminating on-site assembly and enabling quick commissioning upon arrival at the mining area. This integrated mining drilling rig features a crawler chassis that supports autonomous movement and positioning, significantly reducing preparation time for large-scale blasting and improving construction efficiency.

Twin-Screw Air Compressor System for Stable High-Pressure Output

Equipped with a twin-screw air compressor, delivering 1.5-2.0MPa exhaust pressure and 12-16m³/min exhaust volume, it continuously provides stable power for DTH impact drilling. This DTH impact drilling machine ensures drilling efficiency in medium-hard to hard rock formations and avoids operation interruptions due to insufficient air pressure.

High Pulling Force & Rotating Torque for Complex Conditions

With 45KN maximum pulling force, it quickly resolves emergencies like stuck pipes. The rotating torque of 2000-2800N·m, combined with 60-100rpm rotating speed, achieves efficient crushing and drilling in hard rock formations, meeting the rock blast hole drilling needs of metal mines and large quarries.

Retractable Crawler Chassis for All-Terrain Adaptation

Featuring retractable track gauge, 400mm track width, ≤20° climbing ability and 0-2.8km/h walking speed, it easily traverses mining slopes and muddy roads. This crawler-type water well drilling rig adapts to complex terrain of large quarries and metal mines, ensuring equipment movement flexibility.

Pulse Dust Removal & Dual-Mode Control for Environmental Protection & Precision

The pulse reverse dust removal system effectively collects drilling dust, meeting mining environmental protection requirements. Hydraulic pilot + electric dual-mode operation improves drilling positioning accuracy, reduces human error, and ensures the precision of blasting hole positions.

Water-Cooled Radiator System for Continuous Stable Operation

The power system adopts a water-cooled radiator, maintaining stable equipment operation in high-temperature mining environments. This high-performance drilling equipment supports long-term continuous drilling to meet the high-intensity construction needs of large-scale blasting operations.

Technical Parameters

Product Uses

Deep-Hole Blasting in Mainstream Metal Mines (Gold/Copper)

Targeting deep-hole blasting needs of open-pit mining in gold, copper and other metal mines, 20-30m drilling depth and 140-165mm borehole diameter accurately match blasting hole design. The high-torque drilling system efficiently crushes hard rock ore bodies, providing core drilling equipment for large-scale metal mining.

Bench Blasting in Large Quarries

Adapting to bench blasting construction in large quarries, the integrated design enables quick positioning, and the crawler chassis adapts to rugged quarry terrain. 20-30m deep drilling meets the layered mining needs of bench blasting, improving stone mining efficiency and safety in quarries.

Large-Scale Blasting in Infrastructure Projects

Serving large-scale roadbed blasting in infrastructure projects such as railways and highways, the retractable crawler chassis adapts to complex terrain of construction sites. The pulse dust removal system reduces the impact of blasting construction on the surrounding environment, efficiently completing large-diameter deep-hole drilling tasks.

Secondary Crushing Blasting in Hard Rock Mining Areas

For secondary crushing blasting operations in hard rock mining areas, the high pulling force handles stuck pipe conditions, and precise drilling control ensures blasting hole accuracy, reducing blasting blind spots and improving ore recovery rate and operation safety in hard rock mining areas.

FAQ

Q: What is the drilling efficiency of the YQD-165 rig?

A: In medium-hard rock formations, the drilling speed can reach about 1-2m/min (depending on rock quality). The stable air pressure provided by the twin-screw air compressor and the high-torque drilling system ensure efficient progress of large-scale blasting operations.

Q: What are the transportation dimensions of the equipment? Which transportation method is suitable?

A: The transportation dimensions are approximately 4500×2200×2400mm, and the whole machine weighs 8-9.5 tons, suitable for flatbed truck or container transportation. The integrated design eliminates disassembly, enabling quick commissioning upon arrival at the site.

Q: Can this rig operate in hard rock formations?

A: The equipment is suitable for medium-hard to hard rock formations, and the standard drilling tools can meet the hard rock drilling needs of gold/copper mines and quarries. For extremely hard rock, you can contact us to select special hammers and drill pipes.

Q: What is the maintenance cycle of the equipment?
