With the drill-and-blast method a drilling jumbo is used to drill a predetermined pattern of holes in the rock along the tunnel's path. Carefully planned charges of dynamite are inserted in the drilled holes. The charges are detonated in a sequence designed to break away material from the tunnel's path without unduly damaging the surrounding rock. Air is circulated through the blast area to

It would most likely be cheaper and safer
