The development of prediction formulas for the fragmentation from bench blasting has been
reviewed, starting with Koshelev et al.(1971) and Kuznetsov (1973). Much attention has …

Rock fragmentation is one of the most commonly optimized blasting outcomes due to its
significant influence on the efficiency of downstream operations. This paper reviews the …

Fragmentation of granite cylinders having a centric charge with different decoupling ratios
was investigated in blast experiments. Conclusions are made from studying the post-blast …

The capacity of 17 functions to represent the size distribution of fragmented rock is assessed
on 1234 data sets of screened fragments from blasted and crushed rock of different origins …

Delay time is an important factor in the quality of bench blasting. The development and
application of electronic detonators make it possible to control the timing of detonation by a …

Ten functions (Weibull, Swebrec, Gilvarry, Grady and Lognormal, and their bi-component
versions) are fitted to 448 sets of screened fragment size data from blasted and crushed …

The size-energy fan concept formulation is developed into a prediction model of the
fragment size distribution from blast design and rock mass variables. The fragment size is …

Cunningham's use of x 50, the median fragment size, instead of the mean\left ⟨ x\right ⟩ x in
the main prediction equation of the Kuz–Ram model has several times been pointed out as …

Experimental and theoretical papers on the origin of fines in rock blasting are reviewed
against tests made at Montanuniversitaet Leoben and Swebrec, the Swedish Blasting …

The traditional prediction of the rock fragmentation distribution produced by blasting relies
on the Kuz-Ram model. A recent development has been the Swebrec function, a three …
