DTH Drilling Air Capacity Question

DTH Drilling Air Capacity Question

DTH Drilling Air Capacity Question

(OP)
What kind of compressor (CFM,psi) should be employed to drill several 6.5" dia., 30 m. deep vertical bore holes in rock for the installation of ground anchors under a bridge. A track drill EMC 350 with an Air Rotary Head ARH 351 (Torque 270 kg-m) and a 5" down the hole hammer are to be used. I appreciate all your comments.
