Drilling and blasting are processes of excavation which prioritise the controlled use of explosives along with gas pressure blasting pyrotechnics to break rocks.
The process begins with drilling holes in the rock, which will be loaded with explosives. The explosives used vary depending on the composition of the rock. Higher velocity explosives are used for hard rocks while lower velocity explosives are primarily used for soft rocks.
Once the explosives are detonated, the drilling and blasting contractors will then ventilate the area to remove blast fumes. Mucking will then commence, which removes the blasted rock. This is followed by the scaling of walls to remove loosened pieces of rock and the installation of initial ground support.
Drilling is the process of cutting holes into solid materials to create a circular cross-section. A specific type of machine called a rock drill is used for drilling through rocks. This machine can also be used in digging wells, preparing foundations and mineral exploration.
Blasting is the process of reducing a solid rock into fragments with the controlled use of explosives. The explosives used vary depending on the hardness or softness of the rock.
Blasting a rock can cost between $40 to $100 per cubic yard. The size of the rock can also affect the drilling prices especially if the rock is larger than an excavator or backhoe is capable of handling. For more information, you can consult your local drill and blast contractors regarding the price ranges.
