Application
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.
MIROC® Rock Drilling and Ground Support Tools include:
1. Low pressure DTH Hammer
2. Medium pressure DTH Hammer
3. High pressure DTH Hammer
4. DTH Drill bit
5. DTH Drill pipe
