In order to guide safe production in mine,the 3D visualization of mine need to study.Two 3D modeling methods of road way was given intensively,one is to construct 3D roadway model by using line-frame method and based on the 2D contour line of roadway,the other is to construct 3D roadway model based on the section contour line of roadway.Meanwhile,the relevant data structures and the steps of two modeling methods are described in this paper.Based on above said,taking Yinmusi mine for example,3D roadway modeling is made by using Visual C++6.0 as the programming language and OpenGL as the major graphic-manipulating tool.And the two modeling methods are compared from different aspects.
