A test device for testing the erosion of tailings paste stockpiles by rainwater

Abstract

The invention discloses a testing device for testing the corrosion of rainwater to a stockpiling body of tailing paste, belonging to the field of stockpiling of surface tailing paste and mineral engineering. The testing device mainly comprises a testing bracket, a water supplying device, a control device, a spraying device, a stockpiling device, a measuring device and a liquid collecting device, wherein the water supplying device comprises a water pipe, a water storage groove and a water pump; the control device comprises a main control valve, an automatic timing switch, a flow meter, a pressure meter and a secondary control valve; the spraying device comprises a water feeding pipeline, spraying heads and a branch control valve; the stockpiling device comprises a paste stockpiling groove, a moving shaft at the bottom of a groove body, an angle adjusting shaft at the top of the groove body and limiting holes; the liquid collecting device comprises a liquid collecting groove and a liquid collecting barrel; the testing device comprises a TDR (Time-Delay Relay) probe, a data line and a data storage; the surface of an internal steel plate of the stockpiling groove body is provided with a diamond pattern, and the upper part of a side steel plate at the bottom of the stockpiling groove body is provided with a water discharging hole. The testing device disclosed by the invention has the advantages that the structure is simple, the paste stockpiling slope can be adjusted, the spraying amount and the spraying time can be adjusted, the slurry of the tailing is effectively collected, data is automatically acquired, further the model experimental study on the disaster formation and the evolution process of the stockpiling body of the tailing paste is further realized.

Description

technical field [0001] The invention relates to a test device for testing the erosion of tailings paste stockpiles by rainwater, which is mainly used for the test and research of the erosion (scouring) characteristics of rainwater on tailings paste stockpiles, and belongs to surface tailings paste stockpiles and mining industries. engineering field. Background technique [0002] After the ore mined in the mine is processed, the remaining solid waste is called tailings, which is generally discharged in the state of slurry. Tailings are generally stored directly on the surface or used for underground filling. Usually tailings are given priority to underground filling, but underground filling is restricted by various conditions, and many mines cannot use it. Therefore, tailings ponds for stockpiling tailings can only be built on the surface. Up to now, there are more than 12,600 tailings ponds in my country, and there are more than 8 billion tons of tailings in storage, and ...
