DTH hammers and bits are 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. it has the advantage of high flatness, smooth hole wall, high rigid of drill rod and hammer, independent of high axial thrust, no limit of drilling depth, low cost of devices and easiness to maintain.
1.Rapid removal of cuttings; High penetration rate, especially in resistant rock formation;
2.Easy soil and groundwater sampling during drilling;
3.Possible to measure yield estimate at selected depth in the formation;
4.Advantageous in unconsolidated formations with a high risk of caving
