Rock Breaking





With changing times and the introduction of newer technology construction of buildings, roads, dams, tunnels became easier. With passing time rock blasting required to do all of the above mentioned also became easier. Man first learned to use explosives for breaking down big rocks, later he invented equipment, tools and techniques that let him do the same without using explosives. Gunpowder was originally used as an explosive way back in the seventeenth century. At that time it was basically used for mining.

Hydraulic compactors, Concave Removal Tool, deck buster tool. The chisel tool is used while working on soft to medium hard rocks. The moil tool is especially effective for weak metamorphic and sedimentary rocks and is used for concrete breaking , tunneling and trenching. The use of a blunt tool is advised for highly abrasive working conditions e.g. for breaking an oversize rock needing a maximum fracture.
