通过分析突水水流井巷中漫延时空性变化的影响因素,提出了突水过程的三维动态仿真模型架构.经数据模型化、数据规则化、弧巷直巷化及井巷三维网络化处理,生成了井巷空间网络系统.通过研究水流在井巷空间网络中下向漫延、上向升涨的路径算法,构建了突水水流流经井巷的路径网络.结合突水水流流动的水力特征,解算了突水水流的漫延速度和到达时间.建立了能够真实模拟水流漫延过程的时空动态性变化的三维动态仿真模型.以国内某典型矿山的实际数据为例,验证了突水过程三维动态仿真模型的有效性.
By analyzing the influencing factors of the spatiotemporal variation of water and gas flow in water inrush flow, a three-dimensional dynamic simulation model of water inrush process is put forward.Based on data modeling, data regularization, arc lane straight alley and mine roadway 3D network processing, A network of well space network was generated.Based on the study of the path algorithm of water flow in downhole and upward ascending and descending in the space network of well lane, a network of water inrush flowing through the roadway was constructed.With the hydraulic characteristics of inrush water flow , The diffusive speed and arrival time of inrush water flow are solved, and a three-dimensional dynamic simulation model that can truly simulate the temporal and spatial dynamics of water flow propagation is established. Taking the actual data of a typical mine in China as an example, Effectiveness of dynamic simulation model.
