Abstract
Four road tunnels of which the construction conditions were sim ilar were selected in the paper, and laboratory testsand rockmass classification for the tunnels were carried out. A nd the analysis was performed to find out the correlationpattern of tunnel using jumbo drill machine. It wasanalyzed that there was average abrasion of bit from 11.85% to 3.25% per support patterns of tunnel in four tunnels.Drilling parameter happens to fluctuate according to extent of fracture zone.
