In this paper, the basic concept and characters of virtual reality were introduced firstly, then the implementing methods and steps of virtual fully-mechanized mining face based on PC were detailedly discussed by using basic drawing function base OpenGL. The results show that virtual scenes of fully-mechanized mining face can be realizedby the method introduced in this paper, in which the movement of mechanical systems can be controlled by interactive method, therefore, it provids a new means for students to practice, training workers, making information decisions and theoretic study etc.
