Blasting is defined as a chemical/physical/mechanical process including the initiation of explosives for the purposes of breaking materials, moving material, splitting off rock blocks for building, demolishing buildings and construction, and or generating seismic waves. Explosives are often located in drill holes in the rock; however, they may be located on the surface of the rock mass.
