Abstract :
Fragmentation is the process of breaking of
solid in-situ rock mass into several smaller pieces which
are being excavated or moved by material handling
equipment. It is the major concern of any blasting
operation. Information on the degree and size
distribution of fragments within a blasted rock mass is
essential for efficient loading, transport, crushing and
milling operations. An automated image based
granulometry system WipFrag is used to analyze the
digital image of rock photographs to determine grain
size distribution. The method was tested in Dongri
Buzurg open-pit manganese mine of Maharashtra
(India). WipFrag software was found to be useful for
fragmentation analysis of blast fragment sizes in very
short interval of time
