Risk Research on Unsafe Behaviors Based on Entropy-Fuzzy Evaluation Method
The paper constructs an index system with the highest risk weight for each type of work to explore unsafe behaviors of excavation working faces and improve the accuracy of unsafe behaviors control of operating personnel.Based on the entropy weight method and fuzzy compre-hensive evaluation,we established a risk assessment model to analyze and evaluate the unsafe be-haviors.The results show that the risk levels of roadheader drivers and tunnel support workers are critical;the risk levels of water exploration and drainage workers,belt conveyor drivers,and quality inspectors of fully mechanized working faces are relatively safe.Then,the unsafe behav-iors with the largest weight for each type of work are analyzed and evaluated.Based on the risk analysis results of personnel unsafe behaviors on the excavation working faces,improvement measures were proposed to guide the personnel management and improve the intrinsic safety con-struction in coal mines.
