Risk Evaluation and Simulation Analysis of Occupational Diseases in Coal Mine Workers

Abstract

In order to solve the problem of inaccuracy in the evaluation of occupational disease risk due to the characteristics of unknown and uncertainty, the coal mine occupational disease evaluation system was constructed, the weighting method of “AHP+entropy method” was introduced, and the Lagrangian function and European style were used. The distance function is used to obtain the combined weights of occupational disease evaluation indicators, and the unascertained measurement theory is used to construct the occupational disease risk evaluation model. After that, the Arena software is used for simulation analysis, and the continuous space iteration method is used to obtain the priority of coal mine occupational disease influencing factors. A case study on the occupational disease risk of Zhenchengdi Coal Mine is carried out with the method proposed in this paper. The simulation results and evaluation results are consistent with engineering examples, which shows that the evaluation model based on the “AHP+entropy weight method” unascertained measurement theory is practical and accurate. It is feasible and reliable, also can provide a basis for the risk assessment and prevention of coal mine occupational diseases.
