Measurement of Rock Fragmentation by Digital Photoanalysis
The authors describe a new method for measuring the size distribution of rock fragments produced by blasting, tested during recent experimental blasting in Virginia, USA. In this method, photographs of the broken rock are digitized, apparent size distributions are measured, and corrections are made for the effect of overlapping blocks. An unfolding (correction) function, has been derived empirically from measurements on small scale samples of crushed rock. Results of this research show further potential for the investigation of correlations between rock mass characteristics, types of explosives, blasting patterns, and fragmentation.
