Flyrock calculation
WebFlyrock comes in different sizes and shapes, ranging in mass from few ounces to several tons. Persson et al. [1994] referenced flyrock weighing approximately three tons thrown to a distance of 980 ft. The blaster determines the bounds of the blast area, a nd flyrock is not expected to travel beyond the blast area. WebFlyrock is one of the crucial issues in bench blasting, as it is not only a safety concern but also affects the pro ductivity. The percentage of accidents occurring due to flyrock …
