Abstract:

To evaluate the reliability level of mine’s six-system more accurately and reasonably,an evaluation model of six-system was constructed based on entropy weight method and matter element analysis theory. Based on the composition of six systems,32 indexes that affect the reliability of six systems were proposed,the matter element system of six-system reliability evaluation was built through matter element transformation theory,and association degree of individual index to setting assessment level was calculated.Then the weight of indexes to be evaluated were determined by entropy weight method,and the reliability level of mine’s six-system was determined according to comprehensive association degree of evaluation and setting level.The study results show that the evaluation result is identical to actual situation owing to the constructed model comprehensively considered all the reliability affecting factors to the assessment system,which can reflect the reliability situation of mine’s six-system accurately and objectively.

Key words: six-system, reliability evaluation, entropy weight, matter element analysis method, relevancy degree, security analysis, evaluation system, mining engineering
