According to the knowledge sharing difficulty faced to the products research and development of the coal mine drilling machine manufacturing industry, based on ontology the mine hydraulic drilling machine modelling method and to follow the field ontology building principle, a mechanical ontology module of the mine hydraulic drilling machine and a hydraulic ontology module of the mine hydraulic drilling machine were established and an ontology integrated ontology integration method was applied to integrate the two ontology modules.Thus an ontology model of the mine hydraulic drilling machine was established.The model could be applied to infer and search the knowledge of the mine drilling machine.In comparison with the conventional search based on the key words,the semantic search based on the ontology could improve the recall ratio and precision ratio and thus the knowledge sharing in a more large scope and re-utilization could be realized.%针对煤矿钻机制造业产品研发面临的知识共享难题,提出了基于本体矿用液压钻机建模方法,在遵循领域本体构建原则的前提下,构建矿用液压钻机机械本体模块和矿用液压钻机液压本体模块,并采用本体融合的本体集成方法集成2个本体模块,从而构建矿用液压钻机本体模型,该模型可以实现矿用钻机知识的推理和检索,与传统基于关键词的检索相比,基于本体的语义检索可提高查全率和查准率,进而实现了更大范围的知识共享和重用.
