Abstract

Abstract: Introduction: Underground mining is considered one of the most hazardous industries and is often associated with serious work-related fatalities; this paper addresses job-related hazards and associated risks. Method: A risk assessment approach is proposed (Pythagorean fuzzy environment) and a case study is carried out in an underground copper and zinc mine. Results: Results of the study demonstrate that hazards can be categorized into different risk levels via compromised solutions of the fuzzy approach. Conclusion: The study provides a theoretical contribution by suggesting a Pythagorean fuzzy numbers-based VlseKriterijumska Optimizacija I Kompromisno Resenje (PFVIKOR) approach. Moreover, it contributes to improving overall safety levels of underground mining by considering and advising on the potential hazards of risk management. Practical applications: The proposed approach will improve the existing safety risk assessment mechanism in underground copper and zinc mining. Graphical abstract: Unlabelled Image Highlights: We propose a risk assessment approach in Pythagorean fuzzy environment. L-matrix and VIKOR methods are used in the proposed approach. A case study is carried out for mining hazards and risk. A sensitivity and comparison analysis is provided for validation. A risk evaluation including suggested preventive action plans are given.
