【摘要】：矿井突水事故的发生严重威胁着矿井的安全生产和工作人员的安全。论文针对矿井突水事故中的突水路径以及突水范围进行研究,一是研究了突水水流在不同时刻蔓延到的水位与突水范围,二是对突水水流在未来时间段的蔓延趋势进行预测分析,为突水事故的分析处理和水灾预防处理的决策提供技术支持。论文基于图论与网络理论,首次提出了矿井突水路径的无向图宽度优先路径搜索算法。在对矿井突水因素和突水规律进行分析的基础上,以图论为理论依据,将巷道交叉点的标高设定为搜索权重,将水流流向分成下向蔓延和上向升涨两个突水阶段,形成无向图宽度优先路径搜索算法。基于上述考虑,提出了水流网络图的概念与绘制方法。建立了矿井水流网络图信息库,给出了四种典型的突水巷道模型,并提出对应巷道类型的容水水量计算方法,建立了矿井水流网络图信息库模型,确立了矿井容水量与水位的对应关系。通过实例进行了两种突水情况计算,一是通过已知的突水点和某一时刻巷道水位,结合突水路径搜索方法,计算出了该时刻的矿井突水水量,并通过两个时刻的水位变化,计算得出了突水量；二是结合给定的矿井巷道拓扑结构信息,根据突水点和给定的或计算得出的突水量,对未来时间段的突水范围和水位标高点进行了预测计算。将矿井突水路径的无向图宽度优先路径搜索算法在实例矿井中进行应用和验证,计算结果表明：在已知矿井突水点和矿井基础数据信息的情况下该算法准确实现了对突水的水流路径进行搜索和生成,对突水水量进行计算并给出突水范围；通过应用水位传感器的方法计算出突水量或给定的突水量的情况下,对下一时间段的突水水量和突水范围进行预测。
[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.
