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.
