摘要:

为优化不同降雨条件中煤矿工业场地雨水调蓄效果,提出基于SWMM模型的煤矿工业场地雨水调蓄方法。利用基于SWMM模型的雨水调蓄池溢流运算方法,计算煤矿工业场地在降雨中汇水区溢流与管网溢流。根据雨水调蓄池优化模型,围绕厂区雨水调蓄池溢流情况,建立雨水调蓄池优化的目标函数与约束条件,使用非支配排序遗传算法,获取雨水调蓄池排水最佳方案,实现煤矿工业场地雨水合理调蓄。研究结果表明:不同重现期中,该方法可降低煤矿工业场地下渗损失、地表径流量,提升厂区外部出流量与雨水调蓄池的蓄水容积。不同降雨类型中,可降低雨水调蓄池出水口水深与出水口流量。不同降雨时间中,可降低溢流节点数目、溢流时间、溢流深度。

Abstract: In order to optimize the effect of rainwater storage in coal mine industrial site under different rainfall conditions, a method of rainwater storage in coal mine industrial site based on SWMM model was proposed. The overflow calculation method for rainwater storage tanks based on the SWMM model is used to calculate the overflow in the catchment area and pipeline network of coal mine industrial sites during rainfall. Based on the optimization model of rainwater storage tanks and focusing on the overflow situation of rainwater storage tanks in the factory area, an objective function and constraint conditions for optimizing rainwater storage tanks are established. Non dominated sorting genetic algorithm is used to obtain the optimal drainage scheme of rainwater storage tanks and achieve reasonable rainwater storage in coal mine industrial sites. The research results indicate that this method can reduce underground seepage losses and surface runoff in coal mining industrial sites at different recurrence periods, and improve the external discharge of the factory area and the storage capacity of rainwater storage tanks. Among different types of rainfall, the water depth and flow rate at the outlet of the rainwater storage tank can be reduced. In different rainfall times, the number of overflow nodes, overflow time, and overflow depth can be reduced
