Down-the-hole drilling (DTH) 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. These elements combine to efficiently crush rock formations.
A down-the-hole drill (DTH) functions as a jackhammer at the bottom of a drill string. The rapid hammer action breaks hard rock into small cuttings and dust that are evacuated by air, water, or drilling mud.
