Abstract

The invention discloses a simulation tester for similar damage of tailings dam bursting, which is provided with a simulation reservoir, and the dam of the simulation reservoir is connected with a simulation cleugh. The simulation tester for similar damage of tailings dam bursting is characterized in that the bottom of the simulation reservoir at the tail of the reservoir is provided with a jacking pushrod; the jacking pushrod is arranged on a hydraulic cylinder; the simulation cleugh consists of at least two grooves connected end to end in sequence; the neighboring grooves are connected by an adjustable joint; the dam of the simulation reservoir consists of a fixed bracket and at least one movable baffle. The simulation tester for similar damage of tailings dam bursting has the obvious effects of strong compatibility, simple structure, low cost, easy maintenance, and convenient operation, can simulate tailings reservoirs with different heights and volumes, and can all obtain the data like fluid state evolution characteristics of slurry out of the burst dam, the stress field and flow field distribution rules during the moving process of slurry, and the relationship of the alluvial fan scope of slurry and sedimentary thickness with the moving distance of slurry when facing to the grooves of the tailings dam with different bursting widths, directions and slopes.

Description

technical field [0001] The invention belongs to tailings dam simulation test equipment, in particular to a tailings dam burst failure similar simulation test device for simulating and testing the tailings dam collapse. Background technique [0002] Tailings pond is a special industrial building, and it is also a huge hazard source of man-made debris flow with high potential energy. Because of the danger of dam failure, it is the top priority of mine safety. So far, there are more than 200,000 various tailing ponds in use in the world, and some of them have relatively large safety hazards. Because mining enterprises blindly pursue economic interests and ignore the safety of tailings dams, many catastrophic dam failures have occurred in various places. However, through the collection and study of domestic and foreign materials, it is found that the research on tailings dams mostly focuses on environmental pollution and stability analysis, while the research on tailings dam fa...
