Abstract:

In order to ensure the effective function of the emergency system in underground mine，it is necessary to research the reliability of the system.Based on the five aspects of the environment，human，material，facilities and management，this paper combines the entropy method and catastrophe theory to build a reliability evaluation model of emergency refuge system.The factors which affecting the reliability of emergency actions system  were decomposed into three layers，the evaluation index system including 19 indexes was set up and the importance of the indexes was sorted using the entropy method，and then use the catastrophe theory as the evaluation tool.Finally，taking an analysis of the metal mine in Shandong Province as an example，proposed a method to improve reliability according to the results of the evaluation.The study shows that the evaluation model not only detailed and deeply analyze the reliability affecting factors of emergency refuge system，and objectively determine the relative importance of each index.The evaluation result is consistent with the actual situation，provide a new method for reliability evaluation of emergency rescue system of underground mines.
