Blasting is the most frequently used method of excavation since it exploits the tensile strength of rock which is quite less than the compressive strength. Blasting is considered to be a complex system which involves and interplays the mechanical properties of rock mass, in-situ block size and input energy. The process is dynamic and determination of insitu dynamic properties is a difficult proposition. Understanding blastability, therefore, assumes an added dimension. Several approaches have been used and attempts have been made to describe rock-mass blastability in a better way but, still a compete understanding of this factor is lacking. This paper reviews some of the important attempts made to characterize and access rock-mass blastability in chronological order.
