Explosive charge mass and peak particle velocity (PPV)-frequency relation in mining blast
Journal of Geophysics and Engineering, 2010 A new relationship called the mass/peak particle velocity (PPV)-frequency relation in mining blast is introduced in this study. Two well-known formulae of mining engineering and geophysical engineering are joined to create a new formula which relates 'explosive charge' to 'PPV-frequency' at a target location.
