By the flexible material between the two side of simulation box and rear wall and between slope regulating board make simulation box two side and after
The top abduction of wall, while adjusted by the hinge hinge on the bottom plate of the two side of simulation box and rear wall and simulation box
The angle of abduction and locking, make consistent with the tailings dam simulated inside simulation box；
The hinge hinge being arranged on by adjusting between slope regulating board and water-accepting board adjusts the angle between slope regulating board and water-accepting board, makes
The gradient of slope regulating board is consistent with the tailing dam gradient simulated, and is locked slope regulating board using hinge hinge；
Fixed support is adjusted to certain altitude, the outlet of discharge pipe is corresponded to the top of slope regulating board；
Agitator tank is adjusted to its pulp valve using agitator tank lowering or hoisting gear and is higher than fixed support；
(2) pulp valve is closed, opens sand warehouse and sump, CHARACTERISTICS OF TAILINGS SAND and water are injected into agitator tank, is existed by agitator stirring
Tailings mortar is formed in agitator tank, tailings mortar is measured by the silt concertation measuring instrument set on agitator tank side wall and bottom plate
Concentration, sand warehouse and the inventory of sump are adjusted according to surveyed concentration, until the tailings mortar concentration and the institute's mould that are formed in agitator tank
The concentration for intending mine tailing is consistent；
(3) force (forcing) pump, plasma discharge valve and pulp valve are opened, starts to simulate the sorting of tailing dam waterpower；According to the pressure on agitator tank
The gear of flow velocity and flow the adjustment force (forcing) pump for the mortar that electromagnetic flowmeter on the reading and discharge pipe of power table measures, makes plasma discharge
Flow and flow rate it is consistent with the flow velocity and flow of simulated mine tailing；
(4) during testing, high-speed motion picture camera, automatic bed surface Topographical indicator, ultrasonic level gage and laser particle size measurement instrument are utilized
The sedimentary movement process of CHARACTERISTICS OF TAILINGS SAND in simulation box is intuitively shown respectively, CHARACTERISTICS OF TAILINGS SAND water level inside is highly and heavy on tailing dam deposition beach
Diverse location CHARACTERISTICS OF TAILINGS SAND elevation distribution on product beach, and measure mine tailing section size distribution；
(5) sand warehouse and sump are first closed after off-test, the CHARACTERISTICS OF TAILINGS SAND cleared up in simulation box, sump is then turned on after cleaning out,
Experimental rig is washed, clean rear closing sump is washed, then by installed in the two side of simulation box and rear wall and mould
Intending the hinge hinge on the bottom plate of case makes the two side of simulation box and rear wall recover former plumbness up and down, treats that next time, experiment made
With.
