Abstract

Explosive, detonator and detonating fuse are basic tools used for rock excavation. Productivity primarily depends upon the energy content of explosives. On detonation of an explosive chemical energies are released in the form of heat, light, seismic, sound, shock and gas energies. Part of explosion energy is used in rock breakage and the rest escapes into the environment. The first type of the useful energy is called shock energy and the second type is called gas energy. Combined effect of these two forms of energies is responsible for final breakage of rock due to blasting. The paper describes the method used to determine useful energy of explosives using under-water explosion techniques. This technique as well as determination of available energy help in selection of suitable explosives for varying geo-mining conditions.
