This paper, puts forward the method of aligning by division parts to solve the problem of the large amounts of data, and to establish the geology modeling by using Rodrigo matrix algorithm to complete the absolute coordinates for the mine, which is a new method of the geological modeling. By comparison with the coordinate data, it indicates that the error of the method is within the allowed value range for mine modeling, with good applicability. Taking the modeling of Baiyinnuoér Pb-Zn mine area for example, it can facilitate comprehensive mineral resources prediction for the coverage area, especially in perspectives of the 3D deposit modeling and prediction factor spatial characteristics.
