The rock drill is mainly used as an auxiliary tool for the secondary blasting of the large stone and the slipping of the slope in the large open pit mine. It is the main mining tool in small mines, especially in small quarries. Depending on the weight of the pneumatic rock drill , it can be divided into three types: light (normal weight not greater than 22 kg), medium (generally 22 to 30 kg) and heavy (weight greater than 30 kg) rock drills. The pneumatic rock drill uses compressed air to push the reciprocating motion of the piston in the cylinder of the rock drill to impact the tail, and the drill bit works on the rock to break the rock.
