| Abstract: | The main objective of fragmentation by blasting is to achieve the optimum powder
factor, which may be defined as the powder factor required for the optimum
fragmentation, throw, ground vibration, etc. for a specified blast condition to minimize
the overall mining cost. Presently, the powder factor is established through the trial
blasts. However, powder factor may be approximated using rock, design and
explosive parameters. The term blastability is used to indicate the susceptibility of
the rock mass to blasting and is closely related with the powder factor. This paper
presents a review of some of the important studies made on blastability and powder
factor determination using rock and design parameters |
