中文摘要：

研究了数字矿山建设过程中巷道及井下相关构筑物的三维实体形成的关键问题，分析了数字矿山建设中三维井巷设计的重要意义，在此基础上，基于Auto CAD平台，利用VC6．0和Object ARX技术设计开发了采矿设计系统。该系统可以实现三维实体井巷，能很好地解决井巷的三维实体化，并能使其实现过程自动化，取得令人满意的结果。另外，矿山设计中压气管道、通风系统及给排水系统等都可以用此系统来生成。

英文摘要：

The key problems in the formation of three-dimension entity of mine workings and related underground structures in building digital mine were studied and the important significance of three-dimension mine workings in digital mine building was analyzed. On this basis, a mining design system was developed using VC6.0 and Object ARX techniques based on Auto CAD. This system can well solve the problems in the three-dimension entity realization of three-dimensional mine workings and make the realization process automatically done to achieve satisfactory results. In addition, the compressed air piping, ventilation system and water supply and sewage system can all be generated using this system.
