Down-the-hole drilling (DTH) essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation, and air.
Diesel fuel consumption is the most important cost of operating a DTH drilling rig and is one cost that can be effectively controlled through management.
Down-the-hole drilling is to drive the hammer behind the drill bit by compressed air by means of the drill pipe.
The DTH drilling rig is a semi-hydraulic vehicle and the basic functions are controlled by the hydraulic system.
