The　concept　of　ontology　stems　from　philosophy　to　systematically　explain　and　illustrate　the　objective　existence.　This　interpretation　does　not　depend　on　any　particular　language　and　concerns　abstract　nature　of　objective　reality.　Because　of　this　characteristic　of　ontology,　ontology　has　been　widely　used　as　a　way　of　knowledge　representation.　Traditional　ontology　is　defined　as　the　relationship　between　them,　which　is　appropriate　to　represent　the　static　concept.　But　humans　understand　the　real　world　taking　event　as　a　unit.　In　order　to　more　accurately　describe　the　objective　world,　this　paper　proposes　a　method　for　constructing　event　ontology　model　and　applied　this　method　to　the　field　of　mine　safety,　establish　event　ontology　in　the　field　of　mine　safety,　which　is　important　for　knowledge　representation　and　semantic　retrieval　on　mine　safety　event.
