Problems solved by technology

[0004] The technical problem to be solved by the present invention is to propose a tailings dam piping failure scenario construction system and its method for the traditional "prediction-response" method in the tailings dam accident response to the defects of the accuracy and timeliness of the early warning prediction, which is difficult to guarantee. method, before the tailings dam failure accident caused by piping, the accident scene was constructed, and the quantitative and qualitative analysis methods were combined to solve the sudden serious and extraordinarily serious safety accidents

Embodiment 1

[0045] Embodiment 1, reference figure 1 , this embodiment proposes a tailings dam piping failure scenario construction system, including a real-time basic system for obtaining tailings dam seepage stability information, a visualization system for visualizing the tailings dam piping process, and an expert information base; The real-time basic system includes an online monitoring module, an infiltration line calculation module, an exploration information input module, a tailings dam stability analysis module, and a stability evaluation module; the online monitoring module is used to obtain real-time monitoring data, and the monitoring data includes The horizontal displacement and vertical displacement of the dam body, reservoir water level, dry beach length, safe superelevation, rainfall, reservoir image; the soaking line calculation module is used to calculate the soaking line depth of the tailings dam, the soaking line calculation module and The exploration information input m...

Embodiment 2

[0051] Embodiment 2. This embodiment proposes a method for constructing a tailings dam piping failure situation based on the system described in Embodiment 1. refer to figure 2 , including the following steps:

[0052] Step S1, data collection and screening: realized through the online monitoring module and the exploration information input module, and divide the factors that affect the tailings dam piping damage, and eliminate obviously wrong data;

[0053] The first step in visual restoration is information collection and screening. Information sources are divided into dynamic information sources and static information sources. Dynamic information sources refer to factors that are constantly changing during the tailings dam failure process and thus affect the dam failure process, including The seepage velocity of water, the compactness of tailings sand, the height of infiltration line, the height of reservoir water level, rainfall, earthquake; the static information source...

Abstract

The invention discloses a tailing dam piping failure scene construction system and method. The system comprises a real-time basic system, a visual system and an expert information library; in the whole process from data extraction, processing and modeling to animation making, modules in the system cooperate, so that the processing efficiency is extremely high; a visualization technology is adopted, so that a disaster consequence can be presented visually and intuitively, and non-professional personnel also can understand a tailing dam piping failure process carefully and detailedly; on the basis of systematically researching reasons, a mechanism and the process of tailing dam piping failure, an animation scene of the tailing dam piping failure is constructed by virtue of an online monitoring module based on a realistic background that tailing dam failure accidents frequently occur, so that the whole process of the tailing dam piping failure is accurately simulated and failure data is collected; a data result is processed, so that actual working parameters of a tailing dam are reversely deduced; and therefore, targeted opinions can be proposed for tailing dam management departments, and unexpected major and extraordinarily serious safety accidents are effectively avoided.

Description

technical field [0001] The invention belongs to the field of emergency management of tailings dam failure. Based on the example study of expected strategic risks, an emergency preparation plan for in-depth risk analysis is realized, and a tailings dam piping failure scenario construction system and method are proposed. Background technique [0002] my country is a big mining country, and the mining economy occupies a very important proportion in the national economy, followed by the increasing number of tailings dams. Due to the complex engineering mechanical properties of tailings materials and special construction and operation methods, tailings dams have a higher risk of dam failure than reservoir dams. Moreover, once the tailings dam fails, the harm it will cause is unprecedented. Piping is a major seepage damage form of tailings dam failure, and the tailings dam failure accidents caused by piping account for a considerable proportion of the total accidents. [0003] Th...
