In conclusion, the quantification of the risk of slipping of the industrial deposits produced on the environment and the social domain was carried out through two

The risk of slipping of industrial tailings deposits occurs in areas where the slope angle exceeds the internal rubbing angle of the rocky rocks and on or through the base terrain if its slope is greater than the internal rubbing angle of the rocks.

Risk assessment involves identifying the hazards and then assessing the risk of

slipping the industrial deposits they present, by examining the likelihood and

risk matrices in which all the environmental components are analyzed.
