Research On Coal Mine Safety Information Management Based On Blockchain Technology

Blockchain technology has developed rapidly in my country in recent years,and its unique technical characteristics are suitable for information management in various fields.Current coal mine safety information management has problems such as safety information distortion and safety information asymmetry,which pose challenges to mine safety management.To this end,this article takes coal mine safety information as the research object and explores the construction of a coal mine safety information management model based on blockchain technology to improve the problems of information islands and information distortion in traditional coal mine safety information management.First of all,starting from the basics of blockchain technology,systematic analysis and description of related concepts,key technologies and unique attributes of blockchain technology.Using the literature review method,the concept of coal mine safety information was defined.Based on the theory of coal mine accidents,the elements of coal mine safety information management were described in detail,and the current situation of coal mine safety information management was analyzed from the four aspects of man-machine-environment-management;On this basis,analyze its suitability and advantages in coal mine safety information management,innovatively put forward a coal mine safety information management plan based on blockchain technology,which provides a new direction for the safety management of the coal mine participants.Secondly,a model for the application of blockchain technology in coal mine safety information is constructed.The coal mine safety information blockchain model is divided into seven layers,which are operation layer,infrastructure layer,data layer,network layer,consensus layer,contract layer and application layer.It also analyzes the process of smart contracts,information collection,information storage,and information sharing of security information in the blockchain.Finally,this article takes employees,equipment,environment,systems,and government supervision as the entry point,and clarifies that blockchain technology can achieve employee safety quality evaluation,equipment life-span management,equipment failure timely recording,monitoring information traceability,and timely update of system specifications.And take the personnel positioning system as an example to illustrate.It is believed that the technical characteristics of blockchain,such as decentralization and non-tampering,can solve the problems of information islands and information distortion in coal mine safety information management.
