Research On Construction Method And Information System Of Double Prevention System In Non-Coal Mines

The construction of a double prevention system for non-coal mines can be transformed from passive accident prevention to active prevention of hidden dangers,thereby achieving the goal of moving the gate forward and focusing on prevention,which can effectively improve the safety management level of non-coal mines.At present,most non-coal mines still have problems in the construction of the double prevention system,such as unclear construction steps,disconnection of the construction process,and deviation of construction priorities,which greatly reduces the effectiveness of the double prevention system.In order to solve the above problems,the construction of the double prevention system for non-coal mines is studied from the three aspects of construction process,construction effect,and information construction.According to the existing construction process of the double prevention system,the specific construction method of the non-coal mine double prevention system is proposed,which mainly includes steps such as risk assessment unit division,hazard source identification,risk classification,risk management and control,hidden hazard investigation,hidden hazard classification,and hidden hazard management;Define uncontrolled hazards and the failure of hazard control measures as hidden hazards,establish a transmission system for hidden danger investigation and management and risk hierarchical management and control,and strengthenedly change risk management and control;The method for evaluating the risk of operating conditions is improved.The value of the probability of accident（L）is determined by the formula L₁=L_maxq_cin/N,and the concept of"failure frequency"is introduced,to achieve dynamic risk assessment.In view of the non-linear and dynamic characteristics of the construction process of the double prevention system in non-coal mines,the relevant knowledge of system dynamics is used to study it,and the system dynamics model of the double prevention system in non-coal mines is established by using VENSIM-PLE software.Draw out causality diagrams and flow diagrams,and set the relationship between variables.Aim at the construction effect of the double prevention system in non-coal mines,the system dynamics model with different proportions of the safety investment of each part was simulated and ran,and finally,option 3was the optimal construction plan of the double prevention system in non-coal mines.With the goal of risk classification management and control and hidden danger investigation and management,the use of computer network technology,based on the B/S model and Mysql database research and development non-coal mine safety management information systems which combined with double prevention system.The system includes five modules:system management,document management,risk classification management and control,hidden danger investigation and management,analysis and early warning.It can achieve the information management of the double prevention system of non-coal mines,and can further promote the construction and development of the double prevention system of non-coal mines.
