Research On Combination Intervence Of Coal Mine Gas Explosion Near-miss

Gas explosion is one of the most serious accidents in coal mine,many small accident which didn't cause serious consequences will be appeare before each gas explosion,these small accident are known as near-miss in coal mine gas explosion.Therefore,to strengthen the intervention of the study of near-miss will be eliminate before the accident happened,which for the prevention of coal mine gas explosion have great significance.Firstly,the definition of near-miss in coal mine gas explosion have been put forward based on the theory summary.Starting from the three conditions of gas explosion,22 influencing factors of the near-miss in coal mine were explored through literature review and field interview.Secondly,4 common factor and 21 factors were extracted by questionnaire.The intervention measures were extracted to use the method of logical reasoning,and analyzes the influence relationship of the intervention measures to form the intervention system.According to the intervention system,the SD combined intervention model of near-miss of coal mine gas explosion were constructed from the safety of the individual,the safety of the system equipment,the safety of the environmental conditions,the safety of the organization and management.Finally,the simulation model of the combined intervention SD model is simulated by using the system dynamics method.Combined intervention intervention measures were compared and analyzed,found that the combination of intervention measures are effective,and different combinations of intervention strategies to interfere with different effects.On this basis,the implementation process and scheme of the combined intervention strategy are designed.The combination of intervention measures were studied about near-miss of coal mine gas explosion,so that the accident control into the near-miss pre-control,which Benefit from accident prevention.The combination of the near-miss will effectively control the occurrence of coal mine gas explosion,which provides reference in order to improve the level of coal mine safety management.
