Blast Hole Drilling
Blast hole drills are heavy equipment used across construction and mining to directionally drill holes that are then filled with controlled charges. Holes are drilled into the rock and partially filled with explosives, stemming directs the explosive force into the surrounding rock, and detonation causes the rock to collapse.
