In view of the existing problems of the disagree awareness, incomplete content expression and lack of standardization in identification, analysis, evaluation and description of coal mine risk source, on the basis of modern management theory, from the perspective of knowledge management, firstly we analyze the characteristics of risk source and related concepts, and then introduce the construction scheme of knowledge management system of coal mine safety risk based on domain ontology. The design and realization of the system plays an important role in promoting the knowledge potential of coal mining enterprises and improving the decision-making speed and quality of coal mining enterprises.
