Flyrock is an adverse effect produced by blasting in open-pit mines and tunneling projects. So, it seems that the precise estimations and risk level assessment of flyrock are essential in minimizing environmental effects induced by blasting. The first aim of this research is to model the risk level associated with flyrock through rock …

Mining and quarrying. Mining and quarrying are high risk activities which can affect both employees and people in surrounding areas. The task of dumping material over or near edges has led to fatalities. Serious incidents have included fall of ground, mobile plant and truck roll-overs, partial engulfment, explosive fly rock, electric shock and ...
