摘要
在矿井火灾灾变时期，井巷可通行性主要根据巷道内是否具有高温有毒有害气体而确定。避灾路线的选择与灾情的发展及井巷的条件有关。根据灾情的发展情况，作者将避灾路线分为三种类型，即理想的避灾路线、可行的避灾路线和逃生的避灾路线。文中对不同类型的避灾与救灾路线的可通行性提出了判别计算式，对影响井巷通行速度的各种因素进行了分析并建立了相应的计算模型；还提出了求解ｋ条最佳救灾与避灾路线简便适用的新方法。
Fire hazard travel ability of shaft and roadway mainly depends on whether or not there are high temperature toxic gases in the roadway conditions. Based on development of the hazard, the authors have divided the routes into three classes, namely, ideal route, feasible route and escape route. This paper proposes a calculation expression which can be used to assess feasibility of different types of rescue and escape routes. All the factors that influence the speed of travel in shaft and roadway are analyzed and a corresponding model is established. A new method for calculating the best rescue and escape routes are also put forward.
