A DTH borewell machine, also known as a DTH drilling rig, is a professional heavy-duty drilling equipment that uses high air pressure to drive the drill bit to impact and break rock, completing deep hole drilling operations efficiently. Unlike traditional top hammer drill rigs that transfer impact energy to the drill bit through a long drill pipe, this equipment installs the impactor directly at the rear of the drill bit, which enters the borehole together with the bit during operation, greatly reducing energy loss during drilling. Its main frame is made of high-strength alloy steel with anti-corrosion and wear-resistant coating, featuring a compact structure and long service life, suitable for harsh outdoor construction environments. It is widely used in deep hole construction in various geotechnical projects, ensuring stable drilling performance even in hard rock formations.YG series DTH borewell machine offers 5 standardized models, covering diverse drilling diameters, depth, and working condition needs for various construction scenarios worldwide.

Applications of DTH Borewell Machine :
- Open-pit Mining & Quarry Blasting Engineering: Specialized for production blasting holes, pre-split holes, and buffer holes in open-pit metal mines, non-metal mines, and stone quarries. It ensures consistent hole depth, verticality, and spacing, achieving optimal blasting effect and improving mining and quarrying efficiency.
- Water Well Drilling for Civil & Agricultural Use: Designed for domestic water supply wells, agricultural irrigation wells, and livestock drinking water wells in rural and remote areas. With a drilling diameter range of 83mm to 165mm, it adapts to various geological conditions from soft soil layers to hard bedrock, meeting the water intake needs of different scales.
- Slope Support & Geotechnical Anchoring Projects: Applied to anchor cable holes, grouting holes, and anti-slide pile holes in highway, railway, hydropower station slope reinforcement, landslide control, and foundation pit support projects. The maximum horizontal hole height of up to 3.6m meets the high-position drilling needs of steep slope construction.
- Geological Exploration & Foundation Reinforcement Construction: Used for geological exploration coring holes, foundation reinforcement grouting holes, and pilot holes in building foundation treatment, dam reinforcement, and geological survey projects. It can maintain stable drilling accuracy in complex formations, providing reliable data and construction support for engineering projects.
- Municipal & Infrastructure Auxiliary Drilling Works: Suitable for auxiliary drilling operations in municipal road reconstruction, bridge and tunnel construction, and urban pipeline laying projects, including ground reinforcement holes, pipe jacking pilot holes, and monitoring holes. The flexible crawler walking system adapts to the narrow and complex terrain of urban construction sites, ensuring efficient construction without affecting the surrounding environment.
Features of Down The Hole Drill Rig
1. High-Pressure DTH Drilling System for Superior Hard Rock Performance
Equipped with a high-pressure down-the-hole impact system, the equipment delivers continuous and stable high-frequency impact force, which greatly reduces energy loss compared with traditional top hammer drilling rigs. It maintains efficient and stable drilling speed in ultra-hard rock formations such as granite and basalt, with a drilling diameter range of 83mm to 165mm, fully meeting the needs of most conventional deep hole DTH boring machine projects.
2. Heavy-Duty High-Strength Structure for Harsh Environments
The main frame is made of high-strength alloy steel, with precision welding and sandblasting anti-rust treatment, and coated with imported anti-corrosion and wear-resistant paint. The rugged structure can adapt to harsh outdoor construction environments such as high dust, heavy humidity, and extreme temperatures, with a stable overall structure and long service life, reducing maintenance costs during long-term use.
3.Optimized Power & Hydraulic System for Energy Saving & Low Consumption
Equipped with high-power diesel engines ranging from 33kw to 73.5kw, the optimized hydraulic system and combustion system achieve precise energy matching, reducing unnecessary fuel consumption during full-load and idle operation. It delivers the same rated drilling performance with lower diesel consumption, greatly cutting long-term operating costs for users.
4. Flexible Crawler Walking System for Excellent Site Adaptability
All models adopt a heavy-duty crawler walking structure, with a walking speed ranging from 2km/h to 4km/h, which can easily pass through mountainous areas, muddy ground, uneven sites, and narrow construction spaces. The compact body design supports flexible positioning and steering, adapting to complex terrain that cannot be reached by wheeled equipment, greatly improving the flexibility of on-site construction.
5. Wide Adaptability to Diverse Geological Conditions & Drilling Needs
The DTH boring machine supports adjustable drilling parameters, which can be flexibly set according to different geological conditions, adapting to soft soil layers, weathered rock, medium-hard rock, and ultra-hard bedrock. The series provides the highest horizontal hole height from 2.8m to 3.6m, meeting the needs of vertical drilling, horizontal drilling, and inclined hole drilling in various projects, with strong versatility.
