Aiming at the layout problem of underprop equipments in constructing 3-D abnormal space, a Creating method of underprop project is presented in this paper. By analyzing the underprop equipment and the 3-D abnormal space, the optimization model is built for underprop equipments layout. An optimization approach of the model is advanced, then the underprop project is presented. At last, an underprop project is made based on the method in this paper. According to the project, a 3-D space can be built quickly.
