巷道是矿山工程的核心部分,巷道网络建模是数字矿山建设的重要基础。井下人员定位系统是安全避险“六大系统”的重要子系统之一。针对煤矿多水平、巷道式立体相交的网络结构,以新型井下人员定位系统为应用背景,在一组合理简化的基本假设上,提出一种煤矿巷道的单水平网络全局化建模方法。建模内容包括巷道网络的弧段—节点连续网络模型、弧段—节点离散采样模型和模型间的拟合与变换等。建模方法为煤矿全局化人员定位等大型动态监控系统的设计实现提供了合理的框架基础。
Roadway is the core part of mine engineering. Roadway network modeling is an important foundation for digital mine construction. Underground personnel positioning system is safe haven “six systems ” one of the important subsystems. Aiming at a multi-level and lane-crossing network structure of coal mines and a new type of underground personnel positioning system, based on a set of reasonably simplified basic assumptions, a global level one-level network modeling method for mine roadway is proposed. The modeling includes the arc-node continuous network model of the tunnel network, the discrete sampling model of the arc-node and the fitting and transformation among the models. The modeling method provides a reasonable framework foundation for the design and implementation of large-scale dynamic monitoring system such as coal mine personnel localization.
