Abstract: In order to solve repeatability problem existed in detailed design of shearer parts, in combination with structure characteristics of shearer parts, a multi-l evel integration method of shearer parts concept design ontology was proposed. Construction of the cases relation bridge rules and the integration rules were establish ed importantly, the ripe three levels integration method of structure-semantics-specific was improved, and integration process of the shearer CAE design ontology was g iven. At last, the method was proved to be valid by an integrated case of two different chainless haulage shearer design ontology.
