[Abstract]:The occurrence of mine water inrush seriously threatens the safety of mine production and staff. In this paper, the water inrush path and water inrush range in mine water inrush accident are studied. Firstly, the water level and water inrush range that water inrush flow spreads at different time is studied. The second is to forecast and analyze the spreading trend of water inrush flow in the future to provide technical support for the analysis and treatment of water inrush accidents and the decision of flood prevention and treatment. Based on graph theory and network theory, an undirected graph width priority path search algorithm is proposed for the first time. Based on the analysis of the factors and laws of water inrush in mines, the elevation of roadway intersection is set as search weight on the basis of graph theory, and the flow direction is divided into two water inrush stages: downward spreading and upward rising and rising. An undirected graph width first path search algorithm is formed. Based on the above considerations, the concept and method of flow network diagram are proposed. The information database of mine water network map is established, four typical water inrush roadway models are given, and the water capacity calculation method corresponding to the roadway type is put forward, and the information base model of mine water network diagram is established. The relation between mine water capacity and water level is established. Two kinds of water inrush calculation are carried out through examples. First, through the known water inrush point and the tunnel water level at a certain time, combined with the water inrush path search method, the mine water inrush water quantity at that time is calculated, and the water level change at two times is obtained. The water inrush area and water level elevation point in the future time period are predicted according to the water inrush point and the given or calculated water inrush point combined with the given topological structure information of mine roadway. The undirected graph width first path search algorithm of mine water inrush path is applied and verified in an example mine. The calculation results show that the algorithm can accurately search and generate the water flow path of water inrush, calculate the amount of water inrush and give the range of water inrush under the condition of known mine water inrush point and mine basic data information. With the method of water level sensor, the amount and range of water inrush in the next time period are predicted.
