Assessment of the Explosion Accident Risk in Non-Coal Mining by Hasse Diagram Technique

The aim of is paper to address the problem identifying critical factors in analysis non-coal mine explosion accidents as well improve rationality and accuracy risk results. Hence, we developed a identification method for accidents, combining Systems-Theoretic Accident Model Process (STAMP) Rank-order Centroid (ROC) based on Poset decision-making theory. proposed was applied identify engineering cases. Findings showed that four main dangerous events (out twelve identified ones) were primary culprits related which “Blasters without licenses illegal operation” at basic level, event “the confusion about safety management system companies” control failure emergency departments” “public security supervision level. approximate values average rank are 11.56, 10.4, 4.33, 4.33. results consistent with obtained by used case study. This study extends methods risks facilitates formulation effective preventive measures.
