摘　　要：以VC#.net、SQL Server 2008和地理信息系统为平台,对矿井地图进行了具有地理属性开发的研究,建立了图形库、数据库、方法库和知识库,并构建了基于避险设施的矿井火灾应急救援系统。对矿井火灾进行了实时在线模拟,分析和预测了火灾动态发展趋势,实现了矿井火灾烟流传播和最佳避灾路线的动态可视化显示功能。引入安全性、通行效率等因素对灾后巷道通行能力的变化进行修正,制定了基于避险设施的最优避灾路线选择原则和"理想—可行—逃生"等级路线。利用堆栈数据结构对Dijkstra算法进行改进,提高了在线运算速度。该系统已应用到潞安常村煤矿。Based on platforms including VC#. net, SQL Server 2008 and geographic information systems （GIS）, the mine map was developed with geographical attributes. A rescue system based on refuge chambers during the mine fire period was constructed after the graphics library, database, method library and knowledge base were established. Due to real time simulation of mine fire, analysis and prediction of its dynamic trend, the rescue system achieved a dynamic visual display of fire plume spreading and the optimal escape route based on refuge chambers in an underground coal mine. At the same time, roadway safety and traffic efficiency were introduced to amend the traffic capacity of post-disaster roadways. The principles for selecting the optimal rescue route based on refuge chambers were determined, and the “ideal-viable-escape” level of escape routes was divided. Since the optimal escape route was calculated using Dijkstra algorithm which was improved by the stack data structure, the computing speed of the rescue system online increased. The rescue system has been applied to Changcun Coal Mine owed to Lu’ an Group.
