矿井突水仿真构模及系统实现

针对矿井突水仿真问题，分为井巷工程静态模型构建和水体漫延动态仿真2部分进行研究。运用点线化思想规范并构建井巷工程模型，引入当量长度概念统一时间度量参数。结合矿井突水特点，运用增加约束条件的图论及智能搜索算法，研究突水发展过程中水流下向漫延及水位上向升涨2个过程，采用时间步长法构建模拟时钟，预测及再现突水发生前后巷道、水体动态，完成矿井突水的仿真构模算法及系统原型实现。以国内某金属矿山数据为例，检验系统的可行性和有效性，所建模型及系统原型能够为突水预防、救援及研究工作提供技术支撑。

Simulation Modeling and System Implementation of Mine Water Inrush

In view of mine water inrush simulation,the modeling research was divided into two parts:the static modeling of laneways and the dynamic simulation of water inrush spreading process. Based on the point-line concept,the laneways were modeled with equivalent length to unify the parameters of time and length. Combining the characteristics of mine water inrush, graph theory and intelligent search algorithm,the downward and upward water spreading processes during the water inrush de-velopment were researched. With the fixed time-step method,the simulation clock system was established to realize the forecast and reappearance of laneways and water,before and after the water inrush. The simulation modeling algorithm of mine water in-rush was completed and the system prototype was implemented. A typical metal mine in China was exemplified to verify the fea-sibility and effectiveness of the simulation system. The model and the system prototype provided the technical means for preven-tion,rescue and research work of mine water inrush.
