Operation
DTH hammers work by using compressed air to drive a piston back and forth, which in turn strikes a bit that is attached to the end of the drill string. This creates a hammering action that breaks up the rock and allows the drill to penetrate deeper into the ground.Benefits
- Efficient: Can drill holes quickly and efficiently, even in hard rock formations.
- Powerful: Can deliver a lot of impact energy, which allows them to break up rock that would be difficult or impossible to drill with other methods.
- Versatile: Can be used to drill holes in a variety of rock formations, including hard rock, granite, and soft rock.
- Durable: Are built to withstand the rigors of mining and quarrying operations.
Applications
- Drilling blast holes for blasting operations
- Drilling exploratory holes for mineral exploration
- Drilling holes for water wells and geothermal wells
- Drilling holes for anchoring and foundation work

Mining Drill Hammer Exhaust Tube
The exhaust tube, also known as the blow tube or exhaust pipe, is an important component of a mining drill hammer. It is responsible for channeling the exhaust gases from the hammer's pneumatic motor away from the operator and the drilling area.Functions:
- Directs exhaust gases away from the operator: The exhaust tube directs the hot and pressurized exhaust gases away from the operator, preventing burns and eye injuries.
- Reduces noise levels: The exhaust tube can help to reduce the noise levels generated by the hammer, making it a more comfortable tool to use.
- Protects the drilling equipment: The exhaust tube protects the drilling equipment from the harmful effects of the exhaust gases, such as corrosion and erosion. It also helps to prevent debris from being sucked into the hammer.
- The optimum range of hole size for blast hole drilling with DTH is 90 mm to 254 mm (3 ½”–10″). Smaller blast holes are generally drilled using tophammer, and larger holes generally use rotary machines.In other applications, like foundation drilling, DTH hammers can be used with single bit in hole sizes up to . 750 mm (30″). With multiple hammer units CD (Cluster drills) drill holes up to 70″ or 1778 mm.As a rule of thumb, the smallest hole diameter a DTH hammer can drill is its nominal size. A 4 inch hammer will drill a 4 inch (102 mm) hole. The limiting factor is the outside diameter of the hammer, because, as hole diameter reduces, airflow is restricted. Maximum hole size for production drilling is the nominal hammer size plus 1 inch, so for a 4 inch hammer the maximum hole size is 5 inch (127–130 mm).Choosing the right hammer is largely determined by hole size and type of rock formation. Ideally, the size of the hammer should match the required hole dimension as closely as possible, leaving just enough space for cuttings to evacuate the hole.
