| Coal is the main sources of energy in our country, and our country is great power in coal sources. The safety calamity has been frequently occurred, because the disaster is not controlled effectively during the exploitation. If we study causes of disasters, it is the main cause that the coal mine enterprises have not correctly behaviors in the safety integrity, such as the weakly safety consciousness, the serious appearance of"three non-observances", the ineffective measures, besides the natural condition. In order to commending the disasters, it is a significant measure to launch the safety integrity management in coal mine enterprises. The safety integrity evaluation is the major part in the safety integrity management, therefore, it is significant in theory and actuality to perfect the style of arrangement in coalmine safety, to increase the directionality of safety management and to improve the performance of safety supervision.The evaluation system of coalmine enterprise safety integrity was deeply studied with the use of system evaluation and Bayesian networks theories. Theoretical analysis and actuality research ware all applied during the study. This could provide theoretic and technical support to coalmine enterprises. After introducing the principles for building index system and sifting indexes, the evaluation index system of coalmine enterprises safety integrity was put forward, which was based on disaster analysis and seeking advices from experts. Bayesian networks theory was introduced, and then Coalmine safety integrity evaluation model based on Bayesian networks was built, which adopt the Bootstrap method for experts'subject probability aggregation. The measures to improve coalmine safety integrity ware put forward, which ware on the foundation of the preceding study. Finally, a case studied of the evaluation on the safety integrity situation in Henan Ping-yu coal & electricity co., LTD, and some advices to promote the level of the coalmine ware put forward. |
