Three-dimensional solid models and block models of the ore bodies and the stratums in the Hutouya Pb-Zn polymetallic deposit are established by using Vulcan and Datamine software.The spatial variation of the ore bodies’ Pb and Zn grade in the east of the exploration line 67 and the west of the exploration line 117 are analyzed by geostatistic method and a search ellipsoid is obtained and spatial variation of ore bodies’ morphology and ore grade is displayed.The spatial distribution model of ore bodies is summarized to guide ore prediction,or location of possible blind ore bodies.
