Research And Application Of Safety Hidden Danger Investigation And Control System For Open-pit Coal Mine

The investigation and control of hidden dangers in open-pit coal mine safety is an effective way to prevent and control accidents.In order to improve and implement the responsibility system of safety production in open-pit coal mine enterprises and strengthen the safety production work in open-pit coal mine.It is urgent to strengthen research the investigation and control technology of hidden dangers in open-pit coal mine enterprises,research and apply the information system of hidden dangers investigation and control in open-pit coal mine.For this purpose,the thesis analyses and studies what is the hidden danger of open-pit coal mine;how to investigate and control the hidden danger of open-pit coal mine,then the author studies and analyses the present situation of the hidden danger investigation and treatment of open-pit coal mine enterprises that reach the standard of first-level standardization,and puts forward suggestions for their improvement.Meanwhile,it combs the hidden danger investigation and treatment process of open-pit coal mine.The author participated in the examination and acceptance of the standardized classification of open-pit coal mine safety production and obtained the relevant field data.The hidden dangers of open-pit coal mine were analyzed by factor analysis and cluster analysis.Based on that,the factors affecting the hidden dangers were divided into five categories.Then the hidden danger rating of open-pit coal mine is refined,and the hidden danger status of open-pit coal mine is closely related to its business model,which provides theoretical guidance for the dynamic assessment of open-pit coal mine enterprises by relevant departments.Three models for predicting potential safety hazards in open-pit coal mines are studied in this thesis.The prediction results show that the improved prediction model has high accuracy and can provide assistant decision-making for safe production of open-pit coal mine.Finally,on the basis of demand analysis and system analysis and design,this thesis develops a management information system for open-pit coal mine safety hidden danger investigation by using Asp.Net platform and C# language.It realizes the whole process of open-pit coal mine hidden danger investigation and management,and at the same time,the system can forecast and warn the enterprise hidden danger investigation and management situation in advance.Through the research and development and deployment of the system,the preliminary application shows that the system can effectively improve the safety production management level of open-pit coal mine.
