INFLUENCE OF PHYSICO-MECHANICAL PROPERTIES AND GEOLOGICAL DISCONTINUITIES ON ROCK BLASTING

It is now an established fact that rock properties and presence of geological discontinuities affect rock blasting to a great extent. An attempt has been made in this paper to discuss the influence of various physical and mechanical properties of rock and geological planes of weakness on blasting. Strong elastic rocks require explosives capable of developing higher peak strains whereas explosives of lower energy perform better in softer rocks. Suitable orientations of blast patterns with respect to major planes of weakness are described. Various methods of determining the blastability of rocks are discussed. (a) (TRRL)
