DTH Drilling Advantages and Applications 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.

How Can DTH Drilling Rig Save Money On Fuel Consumption? 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.

DTH drilling VS Top Hammer Drilling Down-the-hole drilling is to drive the hammer behind the drill bit by compressed air by means of the drill pipe.

How to Operate a DTH Drilling Rig to Maximize Efficiency? The DTH drilling rig is a semi-hydraulic vehicle and the basic functions are controlled by the hydraulic system.

Common DTH Drilling Rig Types And Working Principle There are two kinds: one is a water well rig that combines impact as well as slewing, such as a spider-installed hydraulic DTH drilling rig.
