Rock drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced mostly in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is commonly known as a rock cut.
Explosives or large rock breakers are the normal methods for excavation of hard rock. restrictions on blasting are getting stricter and the use of rock breakers is not always feasible due to vibrations, noise restrictions or simply too hard rock. Rock splitters offer an alternative method for efficient excavation of large volumes of hard rock without the need for explosives, vibrations or fly rock. The splitter can be mounted from a crane or a normal excavator for open pits or shafts, or mounted on a specialized carrier for horizontal tunneling. For large volumes of rock, there is simply no mechanical method more efficient, safe and silent than the rock splitter.
