Problems solved by technology

[0003] In the prior art, most of the simulation devices for tailings dam failure research focus on simulating the mechanism of tailings dam failure, but cannot simulate the impact on the downstream after the tailings dam breaks
In the study of the mechanism of dam failure, because the water level in the dam area is not only affected by the direct rainfall, but also by the confluence of the surrounding mountains, there is a lack of research on these processes in the prior art
[0004] In terms of water and sand movement after the tailings dam breaks, although the technologies or devices in the prior art can be used to simulate the evolution process of the dam break mud flow, they lack the simulation of the tailings dam break mechanism and cannot Reflecting the runoff inflow process of the tailings reservoir under different rainfall levels, it is impossible to simulate the dam failure mode, and it is also unable to simulate the water and sediment evolution process under different dam failure modes
[0005] The existing tailings pond dam breakage affects downstream devices, which mostly use cameras to monitor. Although they can monitor the movement state of the mud flow, they cannot accurately know the specific flow data of water and sediment after the dam break, let alone monitor the flow of water and sediment after the dam break. Impacts on water quantity and quality in downstream channels
[0006] Tailings pond accident dam break is a complex process affected by rainfall, runoff and influx, etc. It is urgent to develop more suitable devices to simulate the mechanism process of dam failure; and the water and sand discharge caused by tailings pond dam failure will not only bring debris flow risk, and it will also induce serious pollution problems in the tailings reservoir ditches and rivers

Embodiment 2

[0046] This embodiment uses the simulation system in Embodiment 1 to simulate the full collapse mode of the dam body. The steps in this embodiment are basically the same as in Embodiment 1, except that the gate dam 142 in step S1 adopts a concrete dam; the whole process is The dam body full collapse mode is simulated by first filling up the dam body 12 in the tailings dam reservoir area 1, and then pulling out the entire gate dam 142 .

Embodiment 3

[0048] The steps in this embodiment are basically the same as those in Embodiment 2, the difference is that in this embodiment, half of the gate dam 142 is removed to construct a U-shaped breach to simulate the half-collapse mode of the dam body.

Description

technical field [0001] The invention relates to the technical field of tailings pond dam break simulation experiments, in particular to a tailings pond dam break simulation system and method. Background technique [0002] Tailings pond is an important facility to maintain mine production, and it is also a major source of danger. Due to the complex engineering mechanical characteristics of tailings ponds and special construction and operation methods, tailings dams have a higher risk of dam failure than reservoir dams. More and more scientists have begun to study the dam failure of tailings ponds. These studies mainly focus on the mechanism of dam failure of tailings ponds, and then analyze the main factors affecting the dam failure of tailings ponds to provide support for the prevention and control of tailings ponds. . [0003] In the prior art, most of the simulation devices for tailings dam failure research focus on simulating the mechanism of tailings dam failure, but c...
