| 摘 要： | 巷道是井下矿山系统中各种人工要素的主要空间载体,其三维空间构模问题是目前三维地学空间构模研究的重要方向之一。针对该问题的解决,给出了巷道中心线的生成方法,提出了根据巷道中心线和断面进行巷道三维空间构模算法。该算法针对圆形巷道断面和巷道交叉处椭圆断面给出了公式的推导,并利用向量算法实现了该问题的三维空间构模。算法在GIS平台下得到验证和实现,表明该方法稳定、可靠,对今后模型走向工程应用具有重要的理论和实用价值。

| Abstract: | Roadway is the primary spatial carrier among the various kinds of artificial elements in underground mining system.The problem of 3D spatial modeling for mine roadway is one of the most important research fields in 3D geosciences modeling system.In order to solve this problem,the method of generating centerline of roadway is given,and the algorithm of 3D spatial modeling is put forward by using the centerline of roadway and its cross-section.The formula for circular and elliptical cross-sections of roadway have been derived to deal with 3D spatial modeling for mine roadway by using vector algorithm.The algorithm has been verified and implemented in the GIS platform,which shows the proposed algorithm is stable and reliable,as well as has great theoretical and practical value for the further application moving from model to engineering. |
