BLAST HOLE DRILLING
Blast Hole Drills are a type of heavy equipment machinery that is commonly used around the construction and mining industries. These pieces of equipment have the ability to directionally drill holes that are usually then filled with controlled charges.
As the name suggests, drilling and blasting works as follows:
1. A number of holes are drilled into the rock, which are then partially filled with explosives.
2. Stemming, inert material, is packed into the holes to direct the explosive force into the surrounding rock.
3. Detonating the explosive causes the rock to collapse.
