Plataforma de perforación rotativa
Rotary drilling rig is used for drilling rock formations with rock hardness coefficient f≤6 in open pit mines, and can also drill hard interlayer rocks with f=7-11. When drilling, the rotary torque and axial pressure are applied to make the drill bit rotate and feed to cut the rock.
