During the last twenty years’ significant changes of the mining paradigm has been observed mainly related to the transformation of mine methods that have evolved from massive open pit extractions to deep underground mining with reduced ore grades and highly complex geotechnical environments which have posed increasing restrictions on this type of operation.
Despite the vertiginous advance of technology that has helped to overcome many limitations, in addition to the development and improvements of mine methods and risk management, the rock fall events still cause an important number of accidents to workers and/or damage to facilities and equipment in underground mines. This problem emphasizes the relevance of a better comprehension and quantification of the probability of fall of ground occurrence in underground mines by considering information that may be captured at the early stages of a project.
