Trabajo presentado en el VI Simposio Peruano de GeoingenieríaPor: Randal Villar Vivar, Organismo Supervisor de la Inversión en Energía y Minería (Osinergmin).AbstractIn Peru, mining companies are committed to comply with legal and technical standards in order to avoid events that lead to fatal accidents and the Supervisory Body of Investment in Energy and Mining (Osinergmin) to enforce them as a supervisory body. To this end, it was important to have a methodology that allows supervision based on a classification or level of risk, For this reason, Osinergmin supervises compliance with legal and technical provisions in order to verify due compliance with the safety conditions of the infrastructure and facilities of medium- and large-scale mining in all productive stages of the mining activity.This research will use a methodology to obtain a ranking of the mining units and in turn, classify them in one of the five (5) risk levels (Very High Risk, High Risk, Medium Risk, Low Risk and Very Low Risk), which involves the AHP methodology of Thomas Saaty L. and the opinion of experts together with a consistency ratio that allows us to indicate that what is evaluated, analyzed and used is consistent. Likewise, in order to develop the research, several risk factors, both technical and managerial, were used in a general way that lead to or avoid fatal accidents or undesired events and to obtain such data from each mining unit in different risk factors.
