In rock quarry blasting, only 20–30 % of the energy pro-duced by explosives is utilized to fragment and displace the rock mass. The rest of the energy is wasted and produces undesirable environmental impacts such as ground vibra-tion, air overpressure (AOp), flyrock, and back-break (Se-garra et al. 2010; Monjezi et al. 2012; Raina et al. 2014;
