Description
The application is a divisional application entitled 'testing device for tailings paste accumulation gradient', wherein the application number of a master case is 201811376979.7, and the application date is 2018.11.19.
Technical Field
The invention relates to the technical field of metal mine tailing treatment, in particular to a tailing paste accumulation gradient testing device and a use method thereof, and provides a reference basis for engineering design and operation management.
Background
A large amount of tailings are generated in the development and utilization process of metal mineral resources, and the method is a key problem to be solved for sustainable development of the mineral industry in China. The principle of the novel tailing disposal process is that low-concentration tailing slurry in a dressing plant is deeply concentrated to form pasty structural fluid, and the pasty structural fluid is pumped to a discharge point through a pipeline to be stacked, so that the risk of dam break can be effectively reduced, the utilization rate of return water is improved, and the influence on the surrounding ecological environment is reduced. The stacking gradient is an important parameter needing to be mastered in engineering design and operation management of a tailing paste stacking system, and provides a basic basis for problems of determining the occupied area of a reservoir area, calculating the dam construction amount, calculating flood control and the like. For design, whether the accumulation gradient is measured and calculated accurately or not directly influences feasibility of implementation of the whole project on technology and economy; for system operation, the influence factors and rules of the stacking gradient are mastered, manual regulation and control are carried out in the discharge process, the stacking gradient meets the design requirements, and the purpose of safe, efficient and economic storage of tailings is further achieved.
The paste bank is formed as follows: along with the increase of the stacking gradient, the discharged tailings start to be gradually collected and automatically form a beam of open flow, and the open flow flows from the top of the stacking body to the toe of the slope through the beach surface and then is converted into diffusion flow. In the flowing process of the paste slope, the flow velocity is high when the slope is too steep, and the slope is scoured, so that the flow velocity is reduced; and if the gradient is too slow, the flow speed is small, and the gradient is steep due to deposition of coarse tailings. Therefore, the paste accumulation gradient is continuously adjusted dynamically until a dynamic balance is achieved, the tailings are not scoured and are not deposited, and the gradient at the moment is considered to be the accumulation gradient to be achieved in the actual production.
The traditional method generally adopts a simple flat ground discharge test to research the accumulation gradient of the paste, expectedly determines the accumulation gradient of large-scale ground surface discharge through a small-scale accumulation simulation test, does not consider the influence of the scouring effect of the flowing of the tailing slope surface on the accumulation gradient in the discharge process, and is insufficient in the test principle, so that the final test data is not in line with the production practice.
