矿山复杂巷道网络组件式三维建模方法

煤矿复杂巷道(曲线巷道、交汇巷道、变断面巷道)建模是巷道三维建模的难点.现有方法在基于导线测量数据重建复杂巷道网络、尤其是矿山常见的曲线交汇巷道仍存在不足.提出了一种巷道组件式三维建模方法.该方法针对煤矿巷道典型导线测量数据，通过巷道中心线建模、巷道双边线建模、巷道组件三维建模三个步骤，自动构建复杂巷道网络三维模型.实验结果表明，提出的方法鲁棒性好，建模时间随数据量增长呈线性稳定增长.建立的巷道网络三维模型可为智慧矿山建设中的空间、几何、力学等多种分析提供支持.

Component-based 3D Modeling Method for Complex Mine Roadway Network

The modeling of complex mine roadways， such as curved roadways， intersection roadways， and variable cross-section roadways， is the key and difficult point when building the 3D models of roadway network. Deficiencies exists in the existing method when reconstructing complex roadway networks based on traverse data， especially for the curved intersection roadways which are common in mines. This paper proposed a basic component assembly method (BCAM) for the modeling of the 3D roadway network by using the underground survey data of coal mine roadway. By applying three steps of BCAM， namely the modeling of roadway centerlines， the modeling of roadway sidelines， and the modeling of the basic component of roadway (BCR)， 3D models of complex roadway network can be automatically constructed. The experimental results show that the proposed method is robust， and the modeling time increases linearly and steadily with the increase of data volume. The established 3D model of the roadway network can support various analyses on space， geometry， and mechanics for smart mines.
