Pneumatic rock drills are widely used in fields such as mining, tunnel excavation, building demolition, and foundation engineering. In mining operations, pneumatic rock drills are used to drill blast holes in hard rocks for blasting operations. In tunnel excavation, pneumatic rock drills are used to drill tunnel contours in rock or concrete for subsequent construction work. In building demolition and foundation engineering, pneumatic rock drills are used to break and demolish concrete structures, providing convenience for construction.
