尾礦庫大調(diào)洪庫容下的水量平衡計算

打開文本圖片集

〔摘 要〕按我國現(xiàn)行規(guī)范要求，尾礦庫調(diào)洪演算應采用水量平衡法計算，且一次洪水排出時間應小于72 h。但當尾礦庫調(diào)洪庫容可裝下一次洪水總量時，則多出現(xiàn)計算結(jié)果不能滿足規(guī)范要求的情況。通過案例分析，提出可通過擬定更高水頭的條件下得出滿足規(guī)范要求的洪水位，并依此確定符合尾礦庫防洪安全要求的防洪高度。

Abstract  According to the current codes in China， the method of water balance is used to calculate the flood control of tailings storage， and the flood discharge time should be less than 72 hours. However， when the flood control capacity of the tailings storage can accommodate the total amount of the flood， it often occurs that the calculation results cannot satisfy the requirement of the codes. Through case analysis， it is proposed that the flood level that meets the codes requirements can be derived by formulating higher water head， and accordingly， the required flood control height can be finally determined to ensure the safety of tailings storage flood control.

Keywords  tailings storage; flood control calculation; water balance method; flood control height; storage capacity for flood control

尾礦庫是用于貯存金屬、非金屬礦山進行礦石選別后排出尾礦的場所，是礦山重要的安全設施，同時也是重大危險源。（剩余3645字）
