通过测量数据库自动生成的图形,或源于数字化或Auto CAD处理的图形,都存在缺乏巷道网络完整拓扑空间关系的问题,为解决该问题提出了带有拓扑关系的巷道三维数据模型、数据结构及其数据自动处理算法。这些算法包括完整巷道弧段的拆分、数据模型、数据结构、结点的处理、根据向量法判断弧段间的位置关系等。该算法在东滩煤矿中进行了实施验证,结果表明:利用该技术可自动、快速生成巷道拓扑网络图,有助于巷道自动建模、巷道应急救援线路模拟、人员定位轨迹回放等实际应用。

The drawings automatically formed with the measured database would be based on the digitalized drawings or Auto CAD processed drawings and would all lack completed topological space relationship of the mine roadway network. In order to solve the problem,the paper provided the mine roadway 3D data model with the top ological relationship,data structure and data automatic processing method.Those calculation methods would include the arch section separation of the completed roadway, data model,data structure,node processing,arch section position location relation judged based on the vector method and others. The related study in Dongtan Mine was ve rified. The results showed that the technology application could automatically and rapidly form the topologic network drawings of mine roadway,could be favorable to the au tomatic modeling of mine roadway,mine emergency rescue route simulation,personnel positioning tracing replay and other actual applications.
