中文摘要:当发生矿井水灾时,选择有效的逃生路径需要从突水点处水流特征,巷道结构信息以及从业人员的数量等方面加以考虑。为了避免逃生拥挤,建立了一种基于突水点水力学特性分析模型,水中逃生速度模型以及改进的D-K路径搜索算法相结合的多路径逃生模型并进行研究。矿井突水发生后,通过水位上升的速度可以估计出突水点水灾程度,并对突水节点和路径进行筛选。人体在水中的移动速度是随着水位的升高而逐渐衰减的,通过对比巷道水位上升速度与移动速度判断该巷道是否可以作为有效逃生路径。从安全节点处向目标节点逃生时,在允许逃生的时间范围内,利用改进的D-K算法可以使井下人员选择更多的逃生路径,避免发生拥挤。结合王家岭矿井实例分析表明,该模型在一定程度上提高了从业人员的逃生率。

Application of multi escape path model in mine flood
Abstract:When a mine flood occurs, the effective escape route should be considered from the aspects of water flow characteristics, roadway structure information and the number of employees. In order to avoid escaping crowding, a multi-path escape model based on water inrush point hydraulic characteristic analysis model, water escape speed model and improved D-K path search algorithm is established and studied. After the water inrush occurred in the mine, the flood level of the water inrush point can be estimated through the rise of the water level, and the nodes and paths of the water inrush are screened. The movement speed of human body gradually decreases with the increase of water level. By comparing the rising speed and mobility speed of the roadway, can we determine whether the roadway can be used as an effective escape route. When escaping from the security node to the target node, within the time allowed to escape, using the improved D-K algorithm can enable the underground personnel to choose more escape routes and avoid congestion. In combination with the case analysis of Wangjialing mine, it has been shown that the model improves the escape rate of the employees to a certain extent.
