Waste rock storage resulting from underground mining works or surface workings, the power plan ashes well as metallurgical and steel waste, is done in the form of dumps. Embankments as well slopes (which are inclined surfaces side that separates positive forms of relief), are characterized by the same geometrical elements, respectively, height and angle of embankment and their stability depends on the physic-chemical and mechanical properties of rocks that compose them. Cohesion and internal friction angle are the...
