Research status of hidden danger investigation information management system of coal mine and its prospect

Classification and rectification modes of accident hidden dangers in coal mine were summarized. Research status of hidden danger investigation information management system of coal mine were expounded from three aspects of technical support system, information collection mode and function modules. It was pointed out that there were some problems in existing hidden danger investigation information management systems of coal mine including lack of correctness and timeliness assurance function of collected accident hidden danger information and informationization support of emergency response, inability to realize multi-terminal interaction, etc. Development directions of the system were prospected from two aspects of technology and function. In technology aspect, accident hidden danger information of coal mine would be multi-dimensionally analyzed and showed, Internet plus cooperative information processing mode of multi intelligent terminals relating to PC would be built, and the system would be designed by use of micro-services architecture. In function aspect, functions of grouping, custom information pushing and online learn of vocational skills would be supplied, and some key functions would be embedded in mobile phone.
