面向人员定位应用的煤矿巷道网络全局化建模

Personnel location oriented global mine tunnel network modeling

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。

Tunnels are the core of mine projects and tunnel network modeling is an important part of digital mine construction. The mine underground personnel position system is one of the ＂six major systems＂ for reducing risks in mines. Coal mines have multi-level, intersecting tunnel networks that complicate underground personnel positioning systems. This paper used some assumptions to develop a method for single level mine roadway network global modeling. The method uses an arc-node continuous model of the roadway network and the arc-node discrete sampling model with the fitting and transformations between models. This modeling method provids a framework for the design of mine personnel location systems and other large-scale dynamic monitoring systems.
