井下变灾发生后(如火灾、瓦斯爆炸、有毒有害气体溢出等)井下工作人员须在最快时间撤离到安全区域.运用通风网络的两个子图,一个是被污染图,一个是安全区域图,以图论为指导,找出从污染图进入安全图中的最短路径,这就是避灾路线.本文介绍了避灾路线的图像显示,以及在铁法晓明矿的实施应用. Downhole disasters (such as fire, gas explosion, toxic and harmful gas spills, etc.) downhole staff to evacuate to the safe area in the fastest time.Use the two sub-maps of the ventilation network, one is the pollution map, one is the safe area map , Using graph theory as a guide to find out the shortest path from the pollution map into the security map, this is the disaster prevention route.This paper introduces the image display of the disaster avoidance route, and its implementation and application in the Tiefiaoxing mine.
