Abstract

The invention relates to a tailing pond overtopping dam break flood condition determination method and device, and the method comprises the steps: determining a flood storage process curve according to a current flood standard and a flood discharge process line; calculating the highest flood level according to the flood storage process curve and the flood regulation reservoir capacity curve; comparing the highest flood level height with the dam crest height of the tailing dam; and when the highest flood level is higher than the dam crest of the tailing dam, determining that the current flood standard is the flood condition of overflow dam break of the tailing pond. The problem that the simulation result is inaccurate due to the fact that the flood condition is inconsistent with the actualflood condition in the simulation process is solved.

Description

technical field [0001] The present disclosure relates to the technical field of tailings ponds, in particular, to a method and device for determining flood conditions of a tailings pond flooding and dam failure. Background technique [0002] Tailings pool refers to the place where dams are built to intercept valley mouths or enclosures, and are used to stockpile metal or non-metal mines for ore sorting and discharge tailings or other industrial waste residues. The tailings pond is a high potential energy man-made debris flow hazard, and there is a danger of dam failure. Once the accident occurs, it is easy to cause serious accidents. [0003] In order to ensure the safety of tailings ponds, model tests and numerical simulations of flooding of tailings ponds are usually carried out, in which flood conditions need to be determined. At present, it is mainly used as the flood condition by injecting water into the flooding dam failure model of the tailings pond until the floodin...
