Tailing pond instability failure simulation device under earthquake action and experimental method

Abstract

The invention relates to a tailing pond instability failure simulation device under earthquake action and an experiment method, which are used for solving the problem that a tailing pond instability failure simulation device under earthquake action in the prior art cannot simulate earthquake waves of different types and different input forms. Comprising a base, a vibration assembly, a power conversion system, a library body simulation assembly and an information acquisition system, a horizontal vibration table is arranged on the base, the horizontal vibration table is in linear sliding connection with the base, the vibration assembly comprises a horizontal vibration air bag and a vertical vibration air bag, and through vibration of the horizontal vibration air bag and the vertical vibration air bag, the library body simulation assembly can be simulated. Seismic waves in different forms are simulated. The piston is driven by the vibration motor to do reciprocating motion in the cylinder body, a cavity with variable volume is formed between the piston and the cylinder body, and the horizontal vibration air bag and the vertical vibration air bag are connected with the cavity through a pipeline. And the library body simulation assembly is constructed according to an equal-proportion scaling principle according to a to-be-simulated actual mining area.

Description

technical field [0001] The invention relates to the technical field of mine geotechnical engineering, in particular to a simulation device and an experimental method for the instability and failure of tailings ponds under the action of earthquakes. 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, ...
