Description

technical field [0001] The invention relates to a similar model experiment device for dam stacking or dam break of tailings, which belongs to the technical field of mine geotechnical engineering. Background technique [0002] Tailings pond is an important structure in mining engineering. The safety of its tailings dam is not only related to the production and economic operation of the enterprise, but also related to the safety of life and property of the downstream people. In our country, with the vigorous development of the economy, our country's demand for mineral resources has increased sharply. Today, my country has become a big mining country. The annual tailings discharge of 12 kinds of bulk minerals is about 300 million tons. However, due to the large number and distribution of tailings pools in my country Wide, combined with historical factors, management and technical reasons, my country has become one of the countries with high incidence of tailings dam accidents. ...

AI Technical Summary

Problems solved by technology

[0004] However, since there are many factors affecting the stability of the tailings dam and it is composed of bulk materials, it is impossible to study the failure mode of the dam body and the initiation of landslides and debris flows only by indoor conventional geotechnical experiments and field experiments. trigger mechanism

For the stability analysis of tailings dams, the field of mine geotechnical engineering at this stage mainly focuses on site exploration, numerical simulation, and indoor dam experiments. An uneconomical approach. Numerical simulation can ideally analyze the simulated body, but it needs to set corresponding boundary conditions and values, which has certain limitations. Therefore, indoor dam experiment is a desirable method. The dam experiment can simulate the instability of the dam body according to the actual conditions on site, and provide reliable data support for the stability analysis of the actual structure
