煤矿预警信息发布影响因素重要度分析OA北大核心CSTPCD

Mining safety and production dynamics are becoming increasingly severe.Improving the effect of early warning information release is a key to enhance the soft power of emergency information in coal mi-ning enterprises.Therefore,it is necessary to deeply understand and analyze the influencing factors of coal mine early warning information release and carry out the analysis of the importance of influencing factors.Firstly,an improved fuzzy fault tree analysis method was proposed.After analyzing the results of field re-search interviews by the grounded analysis,the influencing factors of coal mine early warning information release were excavated and transformed into the events of the fault tree,so as to construct the failure fault tree of coal mine early warning information release.Secondly,based on the expert scoring and fuzzy fault tree,we analyzed the importance degree of the factors of the failure of coal mine early warning information release and sorted them out.Finally,combining the results of quantitative and qualitative analysis,improve-ment suggestions were proposed to enhance the effectiveness of coal mine warning information release.The results show that the key factors affecting the effective release of coal mine early warning information are information production,release mode,dissemination subject,response linkage and effect evaluation,and the most important basic event is the poor communication between above and below the coal mine.The evalua-tion process organically combines both qualitative and quantitative methods to provide improvement ideas for coal mines to improve the effectiveness of early warning information release.
