Analysis and evaluation of risks in underground mining using the decision matrix risk-assessment (DMRA) technique, in Guanajuato, Mexico

A study applying the decision matrix risk-assessment (DMRA) technique to underground mining in Guanajuato, Mexico, identified critical activities with high accident severity and probability. These included blasting, machinery use, exploitation, fortification, and amacize, which pose significant occupational risks due to suboptimal working conditions. The research classified these activities into three risk categories: those requiring immediate corrective actions, those needing control measures, and those necessitating cessation until safety improvements are made. Proposed solutions align with occupational safety regulations from the Secretaría del Trabajo y Previsión Social, aiming to mitigate accidents through documented compliance with mining activity rules.
