Abstract

The invention discloses a tailings pond disaster early warning method and device based on heavy rainfall weather forecast, and belongs to the technical field of tailings ponds, and the early warning method comprises the steps: obtaining the weather forecast rainfall of a to-be-early-warned tailings pond before a flood season; correcting the weather forecast rainfall according to the on-site real-time monitored rainfall of the tailings pond to be early warned to obtain corrected forecast rainfall; determining a tailings pond reservoir area flood inflow process line; determining a relation lineof flood regulation reservoir capacity and elevation; determining a relation line between the discharge capacity and the elevation; performing dynamic flood regulation calculation according to the tailings pond area flood inflow process line, the flood regulation reservoir capacity and elevation relation line and the drainage capacity and elevation relation line to obtain the highest pond water level elevation in the flood regulation process; and when the highest pond water level elevation in the flood regulation process is greater than or equal to the pond water level early warning value, giving an alarm. According to the tailing pond disaster early warning method based on heavy rainfall weather forecast, the accurate rainfall forecast value of the tailing pond can be obtained, and heavyrainfall disaster forecast and early warning can be conducted in time in advance.

Description

technical field [0001] The invention relates to the technical field of tailing ponds, in particular to a tailing pond disaster warning method and device based on heavy rainfall weather forecast. Background technique [0002] Tailings pond is an important facility for storing tailings after mineral processing in the production of mining enterprises, and it is also a source of danger with huge potential safety hazards. It is not only related to the normal production and operation of mines, but also related to the lives and property safety of downstream people . [0003] Domestic and foreign tailings pond dam break accidents are common, among which the probability of tailings pond disasters caused by heavy rain is over 50%. The main reason is that there is no rainfall disaster forecast for many tailing ponds, resulting in hasty emergency rescue measures. In order to ensure the safety of tailings ponds, most of the tailings ponds above the fourth-class ponds in China have inst...
