Abstract: The paper introduces the concepts of 3D data field visualization technology and digital mine, illustrates the practical application of this technology in the orebody surface modeling, grade block modeling and grade isosurface modeling by a real case of developing a fully home-made mining software named “solid mineral resources estimation and three-dimensional orebody modeling & visualization system” with the authors' participation, and finally envisages the application value and prospect of volume rendering technology in digital mines.

Key words: 3D data field visualization, Orebody surface modeling, Ore-block modeling, Volume rendering
