某中型尾矿库调洪原则及调洪计算方法

Flood regulation principle and calculation method of a medium-sized tailings pond

调洪计算在保障尾矿库的安全运行和防洪作用方面都是非常重要的。本文以一座中型尾矿库为研究对象,为了保证尾矿库和下泄区的安全,首先确定了调洪计算的原则。接着,根据调洪计算的特点,对比了尾矿库和水库的调洪计算方法。然后,对尾矿库泄洪设施进行了方案的比对,选择了设施方案。最后,根据尾矿库的调洪计算方法,进行了调洪计算,确定了相应的调洪水位和泄洪设施的最大下泄流量,也确准了该尾矿库的校核水位以及对应的库容。

Flood regulation calculation is very important in ensuring the safe operation and flood control of tailings pond.This paper takes a medium-sized tailings pond as the research object.In order to ensure the safety of tailings pond and discharge area,the principle of flood regulation calculation is determined first.Then,according to the characteristics of flood regulation calculation,the flood regulation calculation methods of tailings pond and reservoir are compared.Then,the schemes of flood discharge facilities of tailings pond are compared and the facility scheme is selected.Finally,according to the flood regulation calculation method of the tailings pond,the flood regulation calculation is carried out,the corresponding flood regulation level and the maximum discharge of the flood discharge facilities are determined,and the check water level and the corresponding capacity of the tailings pond are also determined.
