摘要: 提出了一种新的三维巷道数据模型。该数据模型以半巷道体为基本的三维构模体元,并根据该体元,抽象出构成该体元的5种基本的构模元素点、弧段、特征连接线、巷道剖面以及基础面元。在对该体元模型进行分析的基础上,详细探讨了该体元所有可能的11种基本类型,并分别给出其三维模型示意图。以这些半巷道体体元模型为基础,就可以构建出完整的地下矿山巷道网络。该项研究丰富了数字矿山理论,对矿山安全生产具有重要意义。

Abstract: A new three-dimensional data model of tunnel had been put forward,semi-tunnel was as volume element to construct the 3D tunnel.According to this volume element,five basic modeling elements were abstracted to form the semi-tunnel.There were point,arc,feature connector line,tunnel section,and foundation surface.On the basis of analysis,data model of semi-tunnel,the eleven possible basic types of semi-tunnel were discussed in detail,and the illustrations of these types' three-dimensional model were given.On the foundation of these types volume element of semi-tunnels,it could build a model of simple tunnel,complex tunnel,and composite tunnel.In terms of above new three-dimensional data model,the complete underground mine tunnel network would be constructed.Thereby the study could enrich the theory of Digital mine,it was significant for development and safety production in mine.
