摘要
文章针对煤矿井下巷道的特殊条件,深入研究了巷道的数据来源和选择巷道三维数据模型的原则,继而把巷道抽象成巷道线,深入分析了巷道线的空间拓扑关系,包括结点之间的拓扑关系,弧段与结点的拓扑关系,巷道线与结点、节点之间的拓扑关系,结点、节点、弧段和巷道线之间的总体拓扑关系。
Articles for special conditions of coal mine roadway, in - depth study of the roadway data source and select principles of road- way three - dimensional data model, then abstract roadway into a roadway lines, in - depth analysis of spatial topological relations of tun- nel line, including topology relationship between nodes, topological relations between arcs and nodes, topological relations between road- way lines and nodes, crunode, overall topological relations between nodes, crunode, arcs, and roadway lines.
