5. Describe DTH bits.
To drill holes in a range of rock types, down-the-hole (DTH)
hammers are used in conjunction with down-the-hole hammers. The
hammer drill bit is built with a splined drive to rotate the drill
bit underground when used in conjunction with a down-the-hole
hammer.
6. What does a "down the hole" hammer do?
Down-the-hole drilling (DTH) essentially makes use of a drill
hammer at the base of the drill string. Three things affect
drilling: air, rotation, and bit load (weight). These active
ingredients work well together to fracture rock.
7. How does drilling into the ground function?
A down-the-hole drill rig, which most experts refer to as a DTH, is
essentially a jackhammer that is attached to the drill string's
bottom. The hard rock is broken up into tiny chips and dust by the
quick hammering action, and they are released through the fluid
(air, water or drilling mud).
