Product application

At present, DTH drilling tool is widely used in underground mining, quarries, hydraulic and Hydro-Power Engineering, water well drilling, Mineral exploration, anchoring hole drilling, geothermal engineering, Subway excavation, another civil engineering.


DTH is one of the most efficient ways of drilling rock, using a rapid hammer action to break the rock into sizeable chips which are then evacuated from the bore hole by the air exhausted from the DTH Hammer. The technique provides fast drilling of accurately aligned, straight and clean holes in most ground conditions.
