DTH Boring Machine
DTH boring machine is a mechanical equipment that can drill holes underground. It is usually used in rock drilling for blasting holes such as mining, power stations, road construction, construction engineering, geological exploration, cement pouring, environmental protection engineering, and other fields. The DTH boring drilling rig can choose different drill bits and drill rods according to needs and can perform drilling operations under different types of geological conditions. The down-the-hole drilling rig usually has an automatic control system that can achieve precise drilling positioning and depth control, improving work efficiency and drilling quality.

Principle of DTH Boring Machine
The essence of down-the-hole drilling is to make the impactor into the hole during the drilling process to reduce the energy loss caused by the impact work transmitted by the drill rod, thereby reducing the impact of the hole depth on the drilling efficiency. The DTH drilling machine is designed based on this principle. It uses the rotation and propulsion of the drill rod and the impact of the impactor to break the rock and form a hole.
Composition and Structure
DTH boring machine is usually composed of the following parts:
- Impactor: directly connected to the drill bit, the piston reciprocates through the gas distribution device to hit the drill tail, so that the drill bit impacts the rock at the bottom of the hole.
- Rotary mechanism: driven by a motor or pneumatic rotating device outside the hole, the impactor and the drill bit are driven to rotate together through the drill rod.
- Lifting mechanism: used to adjust the height and angle of the drilling rig.
- Pushing mechanism: provides the propulsion force for drilling.
- Support mechanism: supports the weight of the entire drilling rig.
- Slag discharge system: discharge the rock powder generated during rock drilling out of the hole.
Working Characteristics of the DTH Drilling Rig
High efficiency: DTH boring machine can reduce energy loss and improve rock drilling efficiency.
Flexibility: Suitable for operations under different geological conditions, the drilling angle can vary from nearly zero to nearly 90 degrees.
Adaptability: Suitable for rocks with medium hardness or above, widely used in small and medium-sized mines.
DTH Boring Machine Application Fields
Down-the-hole drilling machines are widely used in the following fields:
- Mining: The DTH drilling machine is used to drill blasting holes to improve mining efficiency.
- Power station construction: The equipment is applied in the construction of hydropower stations, thermal power stations, etc. for drilling foundation pile holes.
- Road construction: It is widely used to drill blasting holes in the projects of roadbeds, tunnels, etc. in the construction of highways, railways, etc.
- Pile foundation engineering: In construction engineering, it is used to drill pile foundation holes to improve the stability of the building.
