The knowledge discovery and mining of geological field is inadequate, resulting in results of 3D modeling of the geological structure low precision and week practicality. Based on the combining of object-oriented and semantic description method, a three-dimensional spatial data model which can complex geological structure object unified expression of the the three-dimensional expression of the dynamic evolution of complex geological structure; uncertainty for tectonic phenomena to achieve based on rough set theory geological field of knowledge discovery and extraction algorithm; the expression language represented explore the integrated geological knowledge of the rules in the field of production rules and predicate logic using the RuleML structure of rules and evaluation methods, and thus build the geological domain knowledge rule base; in order to better achieve the geological implicit information mining and expression space, construction method to explore the geology field rules engine based on a mix of deductive and inductive method; reasoning method of spatial relationships between geological objects of rule-based engine, accurate description of the geological field object spatial relationship; basis of geological domain knowledge rules-driven, three-dimensional modeling method to explore the complex geological structure, build a model of reliability and accuracy of the evaluation indicators and methods, cross-validation of complex three-dimensional model of the geological structure. For geological analysis to provide effective, reliable three-dimensional model of the geological structure, and to provide a scientific basis and technical support for the engineering decisions.
