Design and Implementation of Non-layered 3-Dimensional Orebody Modeling System

Because of diversity, complexity and poor information about non-layered orebody, it is difficult to be accurately described by regular geometry model. Mining engineers couldn’t accurately estimate the space distribution law of orebody's grade, quality and the total reserve according to the traditional 2-dementional (2D)graphics. So it is necessary to accurately establish non-layered orebody model by a flexible, simple and rapid method. Non-layered 3-dimensional (3D) orebody modeling system was designed based on the analysis of three dimensional data model application. This paper outlines the overall design ideas about the system, and it mainly elaborated how to establish the 3D orebody modeling and how to realize the main function, which has solved the orebody internal model and surface model of integrated modeling. The space characteristics of orebody can be visual analyzed and observed. The system can provide accurate, comprehensive and scientific basis for decision making of mining enterprises on design, production and management.
