Drilling and blasting is the controlled use of explosives to break rock for excavation. The result of rock blasting is often known as a rock cut. The drill and blast procedure is a method that begins with drilling holes into rock after careful surveying and developing a plan. Next, these holes are carefully loaded with explosives. The explosives are then detonated, causing the rock to fracture and crumble.
This ensures that the material (rocks) to be a manageable size that allows excavators to easily move the material from the loading area or bench.
