Frequently Asked Questions
What is top hammer drilling?
In top hammer drilling, the hammer produces percussive force on the drill string above the hole, transmitting shock waves to the drill bit through drill rods or tubes.
Top hammer drilling vs down-the-hole drilling?
The primary difference is hammer placement. Top hammer drilling concentrates activity at the top of the drill string, while DTH drilling places the hammer at the bit location down the hole.
How does Top Hammer Drilling work?
The hydraulic drilling rig's piston generates percussive force transmitted to the drill bit via shank adaptor and drill pipe. The percussion system drives rotation while the air compressor handles dust removal and slagging.
What is DTH in mining?
Down-the-hole drilling involves a drilling hammer at the bottom of the drill string, utilizing bit loading, rotation, and air to efficiently crush rock.
