摘　　要：传统的巷道设计大多采用基于平面的CAD方法,既不能考虑巷道所处的地质特征,也无法直观反映巷道之间的空间关系.借助GIS的空间分析思想,综合考虑巷道与煤层/断层、巷道与巷道之间的空间关系,对巷道进行空间距离分析,从而达到优化设计的目的.巷道三维建模过程中,将巷道设计分解为断面设计和轴线设计,通过拖拉和布尔运算方法生成三维巷道实体模型.在三维地质模型基础上,详细讨论了新建巷道与煤层/断层之间的空间距离的计算方法、新建巷道与既有巷道之间的空间最短距离的计算方法,并形成了巷道优化设计的技术流程.最后将该方法应用于安徽省某煤矿工程,能够清晰地揭示空间任一巷道与周边地质环境和其他巷道之间的空间关系.Traditional design for tunnels is usually based on the method of Computer Aided Design in two-dimension. That can not embody the geological features where the tunnel is through, and also not reflect the spatial relations of the tunnels networks. Based on the space analysis of GIS, the spatial relations between tunnels and the coal seams, the faults and the constructed tunnels can be considered which can be used to implement the optimization design. Here, the tunnel design can be divided into two parts： the section and the axis. The 3D tunnel models can be acquired by extruding the section along the axis, then performing Boolean operations. The geological model is mainly including coal seams and faults. The focus of this paper is establishing the calculation models. Then it discusses how to calcu- late the minimum distance. At last, the procedure of optimization design is acquired and an application example is provided.
