基于物理参数的矿井突水逃生多级规划方法

Multilevel planning method for mine water inrush escape

  • 摘要: 针对矿井突水人员疏散路径规划问题,分析现存静态路径规划方法的不足,继而提出了一种基于物理参数的矿井突水逃生多级规划模型。该模型在充分考虑突水事故发生时人员位置、巷道安全点与路径环境的空间关系及水流蔓延的时空特征的基础上,利用巷道地理空间数据建立初始巷道网模型,将巷道间连接点作为非欧几何中的顶点节点,巷道段作为边节点,并根据巷道坡度对欧氏距离进行修正并将结果作为边节点权值,进而生成巷道网络图初始模型。对实时更新的水流蔓延巷道进行标记,计算巷道通过系数,对网络图进行更新,并利用网络图迭代算法进行动态求解最优路径。

     

    Abstract: In response to the problem of evacuation path planning for personnel in mine water inrush,the deficiencies of the existing static path planning method were analyzed,and a multi-level planning model for mine water inrush escape based on physical parameters was proposed. The model uses roadway geospatial data to establish an initial roadway network model on the basis of fully considering the location of people at the time of water inrush,the spatial relationship between roadway safety points and the path environment,and the spatio-temporal characteristics of water flow spreading. The connecting points between roadways are regarded as the vertices in Non-Euclidean Geometry,and the roadway sections are regarded as the edges. The Euclidean distance is modified according to the slope of roadways and the results are regarded as the weights of the edges. Then the initial graph of a network is generated. The real-time updated flooded roadways are marked,the graph of network is updated by calculating the passage factor of the roadway,and an optimum path is obtained by network graph iterative algorithm.
