| Abstract: | To interpret and delimitate the underground orebody accurately,this paper analyzes the 3D model based on the object-oriented theory.Also,the paper presents the modeling process of orebody,the expression of three-dimensional orebody data model element,the process of decomposing three-dimensional orebody model into different objects which are subsequently abstracted into orebody model class library,and the establishment of a 3D orebody data model.In a case study,a large iron ore 3D orebody model has been established,which demonstrates the effectiveness and practicality of 3D orebody model based on the object-oriented method.The results provide more intuitive,more reliable research means for mine design and production. |
