巷道作为矿井生产系统的主体,其抽象模型的建立是进行矿井灾害预防、重大事故处理、生产组织、资源评估和决策管理等相关分析的基础。从巷道空间关系出发,将巷道抽象为几何网络模型,根据巷道自身的特点,进行相关数据组织和生成规则定义,建立了面向巷道的Geodatabase几何网络模型,并基于巷道几何网络模型拓扑关系,进行了救灾路线分析和突水分析试验,为矿井生产和管理系统空间分析和管理决策奠定了基础。
As the main body of the mine production system, the establishment of the abstract model of the mine roadway is the basis of related analysis such as mine disaster prevention, major accident handling, production organization, resource assessment and decision management. Based on the spatial relationship of roadway, the roadway is abstracted into a geometric network model. Based on the characteristics of the roadway, the related data organization and generation rules are defined. Geodatabase geometric network model oriented to the roadway is established. Based on the topology of the roadway geometric network model, Disaster relief route analysis and water inrush analysis tests have laid the foundation for the spatial analysis and management decision-making of the mine production and management system.
