Low energy loss: The impact energy is transferred directly from the hammer to the drill bit without passing through the drill rod, resulting in minimal energy loss and improved drilling efficiency.
Efficient cuttings discharge: During operation, the hammer uses high-pressure air to blow crushed rock out of the hole, significantly enhancing drilling speed.
High drilling accuracy: Since the hammer is located at the bottom of the hole, alignment is precise, minimizing the risk of deviated or bent holes.
Strong adaptability: Capable of drilling through jointed, fractured, or loose formations, including soil and Quaternary alluvium, as well as inclined blast holes.
High mobility: Compared to roller cone drills, DTH rigs are more compact, lightweight, cost-effective, and easier to maneuver.
Mining operations: DTH rigs are used for drilling blast holes in small, medium, and large mines to prepare for ore extraction and transport.
Road construction: Suitable for deep trench blasting, slope anchoring, and grouting operations in highway and railway construction.
Hydropower projects: Used in dam foundation drilling, slope support, and grouting holes in hydropower station construction.
Building construction: Applied in urban projects for foundation support, ground treatment, and drilling anchor cable or bolt holes.
Ports and waterways: Effective for underwater rock blasting in port and channel construction, supporting port expansion and dredging operations.
Working principle: The DTH drill is a rotary percussion drilling rig with a unique structure. Its hammer is an independent system placed at the hole bottom. Compressed air is delivered through the drill rod to drive the hammer via an air distributor, causing high-frequency impact on the drill bit. The bit crushes rock through combined impact and rotation. Rock powder is blown out by compressed air. The hammer rotates at high speed inside the hole, driven externally by an electric or pneumatic motor via the drill rod.
Basic structure: A DTH drill typically consists of a control panel, electrical system, engine system, hydraulic system, track assembly, winch, drill bit, rotary base, boom, clamping and releasing device, feed beam, drill rod, and lower
Low energy loss: The impact energy is directly transferred from the hammer to the drill bit without passing through the drill rod, minimizing energy loss and effectively improving drilling efficiency.
Efficient cuttings discharge: The hammer uses high-pressure air to blow crushed rock from the hole, significantly improving drilling speed and discharge effectiveness.
High drilling accuracy: Since the hammer is positioned at the bottom of the hole, the direction is well-aligned, preventing tilted or bent holes.
Strong adaptability: Capable of drilling through jointed, fractured, or loose layers, as well as soil and Quaternary alluvium. It can also drill inclined blast holes.
High mobility: Compared to roller cone drills, DTH rigs are more compact, lightweight, cost-effective, and easier to maneuver.
Mining operations: Used in small, medium, and large-scale mines for drilling blast holes, preparing the site for ore extraction and transport.
Road construction: Suitable for deep trench blasting in road and railway construction, as well as slope anchoring, grouting, and other drilling operations.

Working principle: The DTH drill is a percussion rotary drilling rig with a unique structure. Its hammer is independent and located at the bottom of the hole. Compressed air flows through the drill rod to the hammer, which drives the high-frequency impact on the drill bit, breaking rock into powder. The debris is then blown out of the hole. The hammer's high-speed rotation is powered by an external electric or pneumatic motor via the drill rod.
Basic structure: The DTH drill consists of a control panel, electrical system, engine system, hydraulic system, track assembly, winch, drill bit, rotary base, boom, clamping and releasing mechanism, feed beam, drill rods, and lower chassis. The drill bit and rod are key components. The drill bit is made of silicon steel, alloy steel, or air-cooled steel for fatigue resistance and durability, while the drill rod connects the bit, transmitting torque and axial pressure.
