Beschreibung
The purpose of blasting is to fragment rock to aid in its removal as overburden, or to fragment the rock to a size wherby it can be fed into a crusher as the primary stage of a beneficiation process. although blasting is a relatively cheap way of loosening or breaking rock, nevertheless, the mining world is interested in still further reducing the costs of blasting, or alternatively designing ways of making the use of explosives more effective. Work was carried out on blocks of sandstone using mining explosives with electric detonator and a pressure transducer to match powder factors, blast-hole geometry. strength and velocity of blast shock-waves against fragmentation and blastability index. Useful correlations were established.
