Evaluation of the model
What does the DNA-Blast model do?
DNA-Blast is a physics-based computer program (1) that simulates the effect of commercial
explosives in the rock for mining, quarrying and/or civil works applications.
Due to the type of model, split up into a set of elementary mechanisms (called ‘genes’), DNA-Blast
model has been evaluated at the gene level, using on site measurements or laboratory data in
order to guarantee the validity of its model. A gene is considered to be valid when the deviations
between the values measured and those simulated are below 30%. with a behaviour deviating no
more than 30%.
Secondary validation stage evaluate the whole model comparing the outcome with Latin American
blast measured results. As a sum of primarily evaluated gene, the wholes proves it is also
