Product description

 

 

In Top Hammer Drilling the hammer produces a percussive force on the drill rods or tubes, which is transmitted to the drill bit. The feed device is usually attached with a hinged boom to a mobile unit. The percussive system strikes the drill rod, for example 2,000-5,000 strikes per minute, and the rotation speed can be, for example, 60-200 rounds per minute. Together these elements make it possible to drill holes in the hard rock. The excess material (cuttings) is flushed up from the bottom of the hole by means of pressurized air or water. Top hammer drills are primarily used in mining, construction and quarrying of rock material. Top hammer drilling, combined with the “drill and blast” method, makes the whole excavation process extremely efficient.

 

 

 

Comparison with DTH

 

Percussion:

1. Does the real job = breaking the rock.

2. Produced by rock drill or hammer’s impact energy and frequency.

3. Typically between 1500 to 3600 hits per minute.

4. Compared to pneumatic drills, hydraulic drills are capable of higher percussion power and faster penetration rates.

5. Percussive drill rig is built around the hammer or rock drill

6. in percussive drilling rock is broken with impact energy

7. Impact Force per Blow : 20 to 60 Tons

8. Blow Frequency: 30 – 60 Blows/Sec (Top Hammer), 25 – 35 Blows/Sec (DTH)

9. Rod/Tube diameters: 23 – 140 mm

 

 

 

Drilling principle of top hammer

 

1. When the piston hits the shank, kinetic energy in the piston creates a compressive wave in the string of drilling tools, that will cause the bit to penetrate the rock

2. Piston velocity at impact ≈ 10m/s but the compressive wave in the drill steel travels at a velocity of 5180 m/s (velocity of sound in steel)

3. The bit is forced forward and penetrates the rock around 1.0 mm

4. Part of the energy not used to penetrate the rock goes back as a tensile wave and part of it as a compressive wave

 

 

 

Application of tophammer drilling

 

Usually tophammer drilling applied in surface civil engineering, quarrying, dimensional stone quarrying, underground mine development, rock bolting, tunneling and production drilling.
