介绍了某尾矿库运行初期洪水计算、排洪系统泄流能力计算及调洪演算的方法和发现的问题,认为尾矿库运行初期排洪系统泄流能力不足是由排洪隧洞与排水井衔接部分断面较小所致,建议加大衔接断面或设结合构筑物。同时认为设计时调洪演算中最大下泄流量对应排洪系统工作状态宜按孔口泄流状态控制。
This paper introduces some methods and found problems of calculation of flood discharge capacity and calculation of flood discharge of a tailing pond during the initial operation of a tailings dam. It is concluded that the discharge capacity of the flood discharge system in the initial operation of tailings pond is composed of flood discharge tunnel and drainage well Conjunction part of the smaller section, it is proposed to increase the convergence section or set up a combination of structures. At the same time, it is considered that the discharge status of the flood discharge system corresponding to the flood control calculation in design time should be controlled according to the discharge status of the orifice.
