Disaster event ontology model building of coal mine based on multi-level semantic constraints
The informatization and intelligence of coal mine production are inevitable trends in the development of coal mines in China,and the intelligent management of the entire process of mine safety is one of the key issues that urgently need to be solved.We aim to quickly obtain specific information from massive amounts of information related to coal mine safety,such as basic information,geological data,and accident types.Based on the characteristics of multi-source,heteroge-neous,spatiotemporal,and correlation of coal mine safety emergency,event ontology is introduced.Emergency coal mine dis-aster events are taken as research units,with the hierarchical(logical)structure of relevant event classes as the main line,we study the ontology information,types,attributes,and their correlation relationships of coal mine disaster events.Combined with the concept of geological disasters,and divided three levels of disaster type,disaster type and disaster type,the charac-teristics of coal mine production safety accidents is analyzed,and the attributes of coal mine disaster events are determined,thus completing the construction of coal mine disaster event ontology,defining the logical structure of coal mine disaster e-vent ontology,and forming a formalized expression of the semantic hierarchy of coal mine disaster events.The study provides a theoretical reference for the rapid integration and release of mine emergency information in the future.
