Research On Safety-Risk Management Of Ventilation And Prevention System For YinXing Coal Mine

The coal mine ventilation and prevention system is a very important system in the process of coal mine production.The safety condition of the system directly affects the safety situation of the whole coal mine.Therefore the safety management of ventilation and prevention system has vast importance for improving the safety management level of the whole coal mine.In this paper,combined with the actual production research work at Yinxing coal mine,the comprehensive security risk assessment for ventilation and prevention system of Yinxing coal mine was conducted,and the specific preventive measures were given.The research has a certain engineering significance to improve the coal mine ventilation and prevention security.Firstly,from the four aspects of coal mine ventilation and prevention system,the main risk factors affecting the safety of mine ventilation and prevention system are analyzed.Secondly,through the comparison and selection of various evaluation methods,it is determined that methods such as brainstorming,expert method,fuzzy analytic hierarchy process and fuzzy comprehensive evaluation method will be adopted to realize the identification,assessment,response,and control of the safety risks of the ventilation and prevention system.Thirdly,a fuzzy comprehensive evaluation model was established for the Yinxing coal mine,and the identified risk factors were processed using corresponding methods for data processing to obtain safety risk assessment results.Combining with the “Basic Requirements for Coal Mine Safety Production Standardization and Scoring Methods” published by the National Bureau of Coal Mine Safety Supervision,the security risks of the Yinxing coal mine ventilation and prevention system are divided into levels,and each level is assigned a reasonable value,and the security status of the Defence Security System is intuitively reflected based on the evaluation score.Finally,according to the evaluation score,rating and combining with the provisions of "Coal Mine Safety Regulations" to formulate targeted preventive measures.In this paper,the research work has played a good role in improving the safety and preventing the accidents of the ventilation and prevention system.At the same time,it can provide a certain reference significance to evaluate the safety of other coal mine systems and the overall safety assessment of the whole coal mines.
