blast design – Mining and Blasting

2012-10-12· Blast Design: This is meant to be a toolbox for blast design in conventional rock quarrying and open pit mines. This write-up is not meant to give straight answers to the blast design parameters, as every single quarry is unique. However, the general relations between the main blasting parameters; geology, blastability and explosives, will be applicable, and the estimation model is a very good

Blasting mechanics: Blasting design standards : Pit & Quarry

We’ve explored the basics of blast design for a typical rock, with the exception of blast timing, from 1963 through today. The old standards that Ash recommended in 1963 were: KB = 20 to 40 KH = 1.5 to 4 KJ = 0.3 (minimum) KT = 0.5 to 1.0 KS = 1.0 to 2.0. These ratios continue to give blasters basic starting points for blast design, but these are rather large ranges for design.
