  • 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.
