Most of the rock to be excavated is expected to be granitic, both standard granite and porphyritic, or basalt, generally making good ground for drillandblast tunnelling. However there are some fracture zones between the main rock masses.

Construction Planning, Equipment, CHAPTER BLASTING ROCK

"Blasting" is performed to break rock so that it may be quarried for processing in an aggregate production operation, or to excavate a rightofway. Blasting is accomplished by discharging an explosive that has either been placed in an unconfined manner, such as mud capping boulders, or is confined as in a borehole. CHAPTER 13. BLASTING ROCK
