Integrated Down The Hole Drill Rig (DTH Drill Rig) comes into being as the requirements for efficiency and intelligence in mining, foundation engineering and water well drilling operations increase. Compared with traditional split drilling rigs, the integrated design highly integrates the power system, control system, pneumatic system and crawler chassis to form a compact, stable and efficient DTH boring machine, which is an ideal choice for modern drilling projects.

Integrated Down Hole Drilling Rig Characteristics
- Highly integrated design: the core components such as power unit, air compressor and control console are integrated on the same platform, which reduces the transportation and installation time;
- Fully hydraulic drive system: hydraulic drive is used for propulsion, slewing, lifting and lowering, with high control precision and quick response;
- Crawler chassis traveling system: with strong off-road capability, adapting to complex terrains such as mountains, Gobi and construction sites;
- Intelligent control system: support remote control, automatic stop, drilling depth monitoring and other intelligent functions;
- Low-energy and high-efficiency: the air compressor is perfectly matched with the host machine, which reduces fuel consumption and improves drilling efficiency.
Explanation of Down Hole Drilling System: DTH Hammers and Bits
The core actuators in the all-in-one Down Hole Drilling Rig are DTH hammer and DTH bit. Together they form the complete DTH hammers and bits system with the following advantages:
| Component | Function | Features |
| DTH Hammer | Uses compressed air to drive a piston for high-frequency impact | Strong impact force, acts directly at the hole bottom, minimal energy loss |
| DTH Bit | Directly contacts the rock to crush and break it | Made of hard alloy, highly wear-resistant, efficient rock breaking |
Compared with the traditional rotary drilling method, this submerged drilling technology performs better in hard rock formations, with fast drilling speed, stable hole diameter and smooth hole wall, which is widely used in the fields of mine blast holes, water wells, geothermal drilling and foundation engineering.
Application Scenarios
- Mining: large diameter blasting hole construction, fast and efficient;
- Water well drilling: suitable for deep well drilling in hard strata;
- Geothermal development: high drilling efficiency, suitable for deep geothermal holes;
- Foundation pile construction: fast hole formation, improve construction efficiency;
- Slope anchoring reserved holes: adapting to sloping and complex terrain drilling.
