There is considerable scope for improving the outcome of any blasting operation through basic understanding and application of the principles of blasting science and technology. The main objective of Performance of Explosives and New Developments is to sensitize the practitioner to critically examine the various empirical approaches in blasting which may have been in use for a long time, but lack any sound material basis. On the other hand, where the empirical approaches have proven of value, significant additional improvement can be achieved through better understanding of the underlying process. None of the components involved in a blasting operation should be treated in isolation, as they are all interlinked. Fragmentation of rock by blasting represents the first stage in the size reduction process which is essential to extraction of valuable minerals and metals. Therefore, understanding the performance of the explosive and initiators under actual field conditions, and critical assessment of the blast results afterwards are central to effective blast design, improved productivity, and novel applications. Performance of Explosives and New Developments presents the state of the art on explosive energy, its utilization in blasting, and some new developments and innovative applications, and is aimed at academics and practitioners in the field.
