Flyrock calculation
WebFeb 10, 2014 · Flyrock prediction and control is a science. Flyrock follows the laws of physics and derives its energy from the laws of chemistry. There are various predictive models in existence, one of the better ones being a model derived by Victorian firm … WebMay 26, 2011 · Once rock velocity is known then the flyrock range L m (m) is calculated from the equation of ballistic trajectories. For bench blasting, Lundborg et al. [ 29] proposed the maximum flyrock according to ( 1 ): L_ {m} = 260d^ {2/3} (1) An alternative approach was attempted by Roth [ 30] for obtaining the flyrock range.
