Product Features
High drilling efficiency:
Pneumatic DTH drilling rig utilizes air-powered hammer impact, improving drilling speed by 40% vs. conventional rigs in medium-hard rock.
Strong terrain adaptability:
Compact design and crawler chassis enable operation in mountainous, sloping, or remote construction sites.
Low maintenance cost:
The pneumatic structure is simple with a low failure rate; routine maintenance typically involves only replacing drill bits and pistons, resulting in minimal expense.
Environmental friendliness:
No fuel leakage risks, emitting only compressed air exhaust, suitable for eco-sensitive areas.
Main Applications
- Mining industry: Drilling blast holes for coal, metal ore extraction with pneumatic DTH drilling rig.
- Infrastructure construction: Deep-hole drilling for road/railway foundations and bridge pier reinforcement.
- Water conservancy projects: Drilling for reservoir dams, irrigation pipelines, and geothermal exploration.
- Quarry operations: Drilling and splitting for granite, limestone mining to produce building aggregates.
Why choose us
High-Efficiency Drilling Technology Support
We utilize a high-air-pressure technical solution (1.0–2.5 MPa) to help clients boost drilling efficiency by over 40%. A single unit can achieve a daily drilling depth of up to 80 meters (in medium-hard rock), effectively shortening project timelines.
Versatile Adaptability
We offer a range of models covering hole diameters from 80 to 200 mm and depths from 50 to 200 meters. Equipped with crawler chassis and multi-angle drill booms, our equipment operates stably in complex terrains-such as mountainous regions, foundation pits, and tunnels-thereby reducing on-site modification costs for our clients.
Strict Quality and Safety Control
Our products have passed 12 rigorous safety tests (meeting standards of ≤85 dB for noise and ≤2 mg/m³ for dust). Furthermore, the operator cabin features an explosion-proof design that complies with underground operation standards, ensuring complete peace of mind for our clients.
Customized Solutions
We provide pre-sales geological data collection services to optimize equipment configurations based on parameters such as rock hardness and drilling angles. We also support non-standard customizations-including drill rod length and air pressure settings-to ensure the equipment perfectly aligns with the actual requirements of each specific engineering project.
Frequently Asked Questions (FAQ)
Q: What is the maximum drilling depth of the pneumatic DTH drilling rig?
A: Typically 50m - 200m, customizable based on project needs.
Q: Can the pneumatic down - the - hole (DTH) drilling rig be used in wet environments?
A: Yes, it can. However, some additional waterproof and anti - corrosion measures may be required to ensure the normal operation of the equipment in such environments.
Q: Can it work in low-temperature environments?
A: Yes, with optional cold-resistant configuration for -10℃ to 45℃ conditions.
