DTH drilling rig uses compressed air as power to complete all rock drilling operations. It is mainly suitable for open pit mining, construction of foundation excavation, water conservancy, power station, transportation, and other engineering projects, as well as for drilling rock and blast holes. DTH drilling machine is mainly used for rock drilling in open-pit mining, construction foundation excavation, water conservancy, power station, building materials, transportation, and national defense construction, and other projects. It can also drill special-purpose rock holes such as anchor holes, geological pressure measuring holes, and drainage holes. What are the advantages of DTH drilling rig: DTH drilling rig can drill holes in rocks of medium-hard or above (f ≥ 8). Like the rock drill, it has the process of rock drilling and hole formation of impact, rotation, slag discharge, and advancement. The difference is the impact mechanism of the DTH drilling machine-the impactor is in...
