尾矿库溃坝溃口发展状态模拟试验

Simulation Test of the Development Status of the Breach of Tailings Dam Break

我国尾矿库数量众多,早期建设的尾矿库标准偏低,存在较大的安全隐患。尾矿库一旦发生溃坝,将对其下游居民的生命财产安全造成巨大损失,并导致严重的环境污染。为此,需进行尾矿坝溃坝试验研究。在尾矿库溃坝试验中,由于每座尾矿库的具体情况不同,很难按照严格比例进行物理模拟,因此试验中主要采用概化模型,通过试验设计,对影响尾矿库溃坝的部分比变量进行研究,找出一般规律,为尾矿库溃坝治理提供参考。

There is a large number of tailings in China,the standard of the early period construction of tailings is low,the potential safety hazards is serious,if the tailings dam break is occurred,the life and property of the downstream residents will be threatened seriously and the significant environmental pollution could be caused. So,it is necessary to conduct the test of tailings dam break. During the test process of tailings dam break,due to the different specific circumstances of each tailings,so,it is difficult to conduct the physical simulation test based on the proportion strictly. Therefore,the generalized model is adopted in the test design in this paper,part of the proportion variables that affecting the tailings dam break are analyzed to discuss the general rules and some relative conclusions are drawn to provide some reference to deal with tailings dam break.
