Dynamically Planning Method Of Mine Water Inrush Disaster Rescue Route Based On Three-Dimensional Roadway Network

Mine water inrush disaster is one of the most common mine disasters.Mine water inrush disaster is not only harmful,but also has a long duration.While the water inrush accident occurring,how to make feasible route planning of emergency rescue to build the last line of defense in the process of safe production,has become the top priority in the work of mine safety in our country at present.Therefore,it has great practical value to study rescue route planning for mine water inrush disaster based on three-dimensional space network analysis method and virtual simulation technology.The simulation method of rescue route planning for mine water inrush disaster is studied based on three-dimensional space network analysis in this paper.Firstly,the basic elements of the three-dimensional tunnel network model of the mine are abstracted and described.The topological relationship between the elements of the three-dimensional tunnel network model of the mine is defined.The data structure and storage structure of the three-dimensional tunnel network model of the mine are described.The calculating indicators of the edge weight in the three-dimensional roadway network model is determined,and the concept of dynamic comprehensive weight is proposed.The above works provide a three-dimensional network model for rescue route planning for mine water inrush disaster.On this basis,the rescue route planning process is designed as two phases:the mineworkers underground searching route planning,and the rescue return route planning.Based on the idea of Breadth First Search(BFS)of graphs and Dijkstra algorithm,a single-target rescue route planning algorithm is designed and implemented.Combined with Floyd algorithm,a multi-target rescue route planning algorithm is designed and implemented.Finally,the feasibility of the rescue route planning algorithm for mine water inrush disaster designed in the paper is proved by simulation experiments.In the simulation experiments,the rescue routes are dynamically planned and adjusted in the rescue route planning algorithm by analyzing the total amount of water inrush and the scope of water flooding in real-time.Furthermore,the dynamic visualization of the rescue route planning process and result is realized in three-dimensional space.With the dynamic planning method of rescue route for mine water inrush disaster studied in this paper,the basic parameters of the mine can be quickly retrieved from the database,the water level in the roadway is solved,the travel speed of the mineworkers is calculated,the position of the personnel is updated,so the function of dynamically planning or adjusting the rescue route is realized.Therefore,the planned route is more in line with the actual needs of emergency rescue.The research results in this paper can provide powerful method support for rescue route planning for mine water inrush disaster,and can effectively assist the rescue decision-making of mine water inrush disaster,which are of great significance for improving the level of mine disaster prevention and mitigation.
