- ÍtemPronóstico de la mortalidad minera subterránea en Colombia 2005-2022(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Barrera Sabogal, Juan Camilo; Vargas Pedraza, Mateo; González Veloza, JohnMining activities in Colombia represent 53% of emergencies resulting from the exploitation of minerals such as gold and coal in underground mines. Throughout this study, we seek to identify whether the contingency measures for the 2005-2012 and 2013-2022 periods will be applied and will affect mortality rates over time. Therefore, historical analysis is carried out supported by a database provided by the mining authority, with a sample size (n=936), represented in the four departments with the greatest impact on the analysis (Antioquia, Boyacá, Cundinamarca, and Norte de Santander), to prevent possible emergencies, based on an ARIMA prediction model, whose optimal selection criterion was the Akaike, with a Mae test type error margin of deaths per month of (4.7) and with this determine the degree of effectiveness of the measures adopted.
