Research On Spot Check And Patrol Inspection Mode And Its Informatization Of The Potential Hazard In Coal Mine

In order to optimize the way of the potential hazard investigation and treatment in coal mine,and improve the efficiency of the potential hazard investigation and its information management.According to the requirements of intelligent coal mine construction for safety information management,this paper analyzes the main problems existing in the potential hazard investigation,and studies the method of integrating the spot check and patrol inspection mode and its information management into the potential hazard investigation in coal mine.Firstly,through the data statistical analysis of the potential hazard from multiple angles,the distribution characteristics of the potential hazard data in space,time,classification and classification are obtained,and the safety inspection route of the potential hazard are determined.Secondly,aiming at the important and high-frequency potential hazard,combined with relevant standards and specifications,statistical analysis and traceability analysis of the potential hazard data,the content of safety spot check of the important potential hazard is determined.Then,a keyword extraction method of the potential hazard data based on TF-IDF and TextRank algorithm is proposed,and the content of safety spot check of the highfrequency potential hazard is determined through data mining.Finally,an information system of spot check and patrol inspection is designed,which includes inspection plan management,spot check content management and spot check management,The system application analysis shows that the efficient implementation of the spot check and patrol inspection mode of the potential hazard can ensure the timely reporting of the important potential hazard and avoid missed inspection,realize the accurate spot check of the high-frequency potential hazard,and effectively promote the continuous improvement of all staff participation and standardized potential hazard investigation and treatment.
