矿井巷道时空数据模型研究及其动态建模

Research on the spatial temporal data model of laneway and it's dynamic modeling

时空数据模型是时态三维矿山地理信息系统的基础,巷道作为地下开采矿井的主体,其时空数据模型的组织方法直接影响系统的运行效率。基于图论基本原理,本文充分利用ArcGIS平台提供的Geodatabase几何网络模型,根据巷道特点进行数据组织并定义计算规则,建立了基于事件的基态修正巷道时空数据模型,该模型融合了基态修正模型和基于事件的时空数据模型的基本思想,将时间引入巷道的三维拓扑关系,实现了按时间动态生成Multipatch三维巷道模型。矿井巷道时空数据模型的建立,强调了时间与空间的密切联系,为矿山动态开采、动态管理和动态监测等提供了有效的技术途径。

Spatial temporal data model was the base of temporal 3 D Mine Geographical Information Systems.As the main body of mine production system,organization method of laneway spatial temporal data model has become the direct recognition of system running efficiency.According to graph theory fundamental principle,a laneway update spatial temporal data model based on event was found based on the geodatabase geometric network model provided by ArcGIS.The spatial temporal data model was organized and calculated through the laneways＇characteristics.Compromising the basic ideas of ground state correction model and spatial temporal model based on event,time was introduced into the laneway topological relationships between 3 D and the 3 D Multipatch laneway model was created dynamically.This laneway spatial temporal data model studied here,who emphasized the close relationship between time and space,provided an effective technical approach for dynamic mining,dynamic management and dynamic monitoring in mining.
