【摘要】 在冶金矿山开采时形成的尾矿坝,具有坝身高、库容小、泄量大等特点,一般用塔式进口的泄洪洞泄洪.本文主要依据白马铁矿尾矿坝泄洪洞的系统试验资料,探讨高尾矿坝塔式进口泄洪洞的振动特性、泄流能力、压力分布、水头损失、岔洞群特性、挟气条件以及模型相似律等若干共同性的水力学问题.更多还原

【Abstract】 Tailings dams which are formed by extracting metal mines are characterized by high dams small reservoir capacity and large discharge, and water tunnels with pagoda entrances are generally adopted to let out discharge. On the basis of systemmatical experimetal data of the tailings dam tunnel of Bei Ma Iron Mine mainly, some common hydraulic problems in water tunnels of high tailings dams are investigated, such as vibriation characteristics, passing discharge, pressure distribution, head losses, characteristics of fork tunnels, conditions of carrying air and model similar law, etc..更多还原
