Mining Blast Hole Drilling Rig YQD-180

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 Parameter

Product Uses

Blasting Drilling in Hard Granite Mines

Targeting hard rock blasting needs of granite mines, 25-30m deep drilling and 165-180mm large borehole diameter accurately match blasting hole design. The 3500N·m high rotating torque efficiently crushes hard granite ore bodies, providing core drilling equipment for large-scale granite mining and improving ore mining efficiency and recovery rate.

Roadbed Blasting in Railway/Highway Infrastructure

Adapting to roadbed blasting construction of large-scale infrastructure projects such as railways and highways, the integrated design enables quick positioning, and the crawler chassis adapts to complex terrain of construction sites. 25-30m deep drilling meets deep crushing needs of roadbed blasting, improving infrastructure project progress and safety.

Bench Blasting in Large Hard Rock Quarries

Serving bench blasting operations in large hard rock quarries, the water-cooled radiator system supports long-term continuous drilling, and the pulse dust removal system reduces dust pollution. The 165-180mm large borehole diameter meets large stone crushing needs of quarries, improving stone mining efficiency.

Hard Rock Foundation Blasting in Water Conservancy Projects

For hard rock foundation blasting in water conservancy hubs and reservoirs, the high pulling force handles stuck pipe conditions, and precise drilling control ensures blasting hole accuracy, avoiding blasting impact on water conservancy foundation structures and ensuring construction safety and stability.

FAQ

Q: What is the drilling efficiency of the YQD-180 rig in granite formations?
