Problems solved by technology

At present, in order to simulate the transport process of particulate matter when the tailings pond overflows, the double-layer flow model proposed by Zech et al is used to calculate it. However, in this type of model, the assumption that the concentration of the bottom muddy water layer is constant is different from The

Abstract

The invention provides a tailing pond dam break risk estimation and emergency response method and device and electronic equipment, and relates to the technical field of tailing pond dam break emergency response, and the method comprises the steps: building an erodible dam overtopping burst model based on initial dam break influence parameters obtained in advance; calculating the discharge flow and the breach broadening after the dam break of the tailings pond based on the erodible dam overtopping burst model; determining dam break influence data of the downstream channel through a pre-established planar two-dimensional dam break flood routing model; and estimating the dam break risk according to the discharged flow, the breach broadening and the dam break influence data of the downstream channel, and determining the emergency response grade. According to the method, the accuracy of risk estimation of tailing pond dam break is improved, the safety early warning effect is further improved, and the timeliness and accuracy of emergency response are improved.

Description

technical field [0001] The invention relates to the technical field of tailings pond dam break emergency response, in particular to a tailings pond dam break risk estimation and emergency response method, device and electronic equipment. Background technique [0002] Generally, when the tailings pond collapses, the slope of the bed surface is steep, the velocity of the water flow is relatively high, and the composition of the sediment particle size distribution is relatively complex. In the previous process of safety assessment and emergency management of tailings ponds, qualitative assessment methods were often used for dam failure risk assessment. Because the method is simple and the content is single, the assessment results of risk assessment are not convincing, resulting in the division of emergency response levels. Unreasonable, insufficient emergency response capabilities, and untimely emergency rescue. [0003] In view of the existing problems in qualitative evaluati...
