Research on the Construction and Application of Knowledge Graph in the Field of Coal Mine Safety Monitoring System

On the basis of summarizing the knowledge sources in the field of mine safety monitoring system, a domain knowledge graph was constructed in a top-down manner. The technical implementation methods of knowledge source acquisition, knowledge extraction, knowledge storage and display were analyzed, and the research results were applied to the analysis of abnormal situations in the safety monitoring system. The T0 alarm situation in the mining face was analyzed, and the feasibility of the technology was demonstrated. The research results have filled the knowledge gap between on-site technicians and coal mine safety monitoring systems, laying the foundation for the intelligent development of coal mine safety monitoring systems.
