Dam piling and breaking simulation device for tailings pond

Abstract

The invention relates to a heap dam break simulation device of a tailing pond. The heap dam break simulation device is used for solving the problem that a heap dam break physical simulation device in the prior art is difficult to simulate the dam break of the tailing pond under various different natural conditions and different working conditions. Comprising an earthquake simulation system, a reservoir body simulation assembly, a rainfall simulation system and an information acquisition system, and can simulate extreme conditions such as earthquakes, heavy rainfall, flood overtopping, seepage drainage failure and the like, and situations of coupling of various disasters; through model test and numerical research, the disaster formation behavior evolution process and disaster formation characteristics of the tailings pond under different conditions are explored, and through reconstruction of different dam bodies, the disaster resistance characteristics of different dam body structures are known, the influence of factors such as reservoir capacity, material characteristics, structural forms, extreme conditions and reservoir periphery topography on the disaster formation mode of the tailings pond is revealed, and the disaster formation model of the tailings pond is constructed. A theoretical basis is provided for heightening and protecting a tailing dam, and the method has important significance on research on a fine-grained high tailing pond.

Description

technical field [0001] The invention relates to the technical field of mine geotechnical engineering, in particular to a dam burst simulation device for tailings ponds. Background technique [0002] The tailings pond is one of the three major production facilities of metal and non-metal mines. There are 8,869 tailings ponds in my country, and most of them have reached or approached the design capacity and are facing closure. Therefore, many mining companies face the problem of building new tailings ponds in the later stage. However, the "Work Plan for Preventing and Resolving Tailings Pond Safety Risks" issued by the Ministry of Emergency Management in 2020 clearly requires: starting from 2020, on the premise of ensuring the normal production, construction and development of the shortage or strategic mineral mines, the number of tailings ponds in the country In principle, it will only decrease, not increase. At the same time, due to the high cost of new tailings ponds, str...
