摘要
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.
The architecture of three-dimensional dynamic simulation models for water inrush processes in underground mines was proposed by analyzing the influencing factors of spatial and temporal changes when water inrushes spread in roadways. A roadway space network system was developed through data modeling and regularization, transformation from arc lanes to straight lanes, and three-dimensional network processing of roadways. The path network of water inrush flowing through roadways was formed based on the path algorithm of water spreading downward and upward. The spread speed and time of water inrushes were resolved in combination with the hydraulic characteristics of water inrush flowing. In such a way, a three-dimensional dynamic simulation model was established which can simulate the spatial and temporal dynamics of water spread processes. A typical mine in China was exemplified to verify the feasibility and effectiveness of the established model.
