Water layer 3, pervious bed 2 and close and have rubber sheet gasket 4 and be bolted in the middle of water layer 3, pervious bed 2, closes water layer 3 and rubber sheet gasket
Multiple permeable aperture is had on the outward flange of 4；Two supports 5 it are fixed with on described slip container 1；Described agitating device 2
Processed by hollow steel pipe, a diameter of 30mm of hollow steel pipe, a length of 15mm.
A kind of mine tailings sedimentation permeance property assay method, the method comprises the following steps:
Step one, configuration desired concn, the tailing slurry of grade composition, precalculate required accurate tailings, clear water matter
Amount；
Step 2, the tailing slurry configured uniformly is poured in mine tailings sedimentation permeance property determinator, use
Agitating device stirs five to ten minutes clockwise, makes tailing slurry reach homogeneous fluid state；
Step 3, range estimation be after tailing slurry reaches isotropic stable state, start to record slurry level height the most in the same time,
Tailings layer height, infiltration water quality；
Step 4, tailings complete sedimentation and process of osmosis laggard row Data Management Analysis, draw tailings settling height, ooze
The time dependent curve of water quality, and analytical data rule, form final research report.
The invention have the benefit that the present invention tailings settles permeance property measures procedure decomposition is four main steps
Suddenly, this method can realize the sedimentation permeance property mensuration of tailings under different situations by simple device and operating procedure,
Solve the most commonly used assay method and be difficult to simulate dead zone, down-hole practical situation, the difficult problem that measurement result deviation is bigger,
Measurement result more scientific and effective, degree of accuracy is high, the most easy to operate.It is a kind of simple and easy to do, safe and reliable
Device and new method.

Detailed description of the invention
Refering to Fig. 1 Fig. 5, a kind of mine tailings sedimentation permeance property determinator.This device includes slip container 1 and stirs
Mix device 2；Wherein said slip container 1 is processed by lucite tube, and bottom has permeable aperture；Described stirring dress
Put 2 to be processed by hollow steel pipe, a diameter of 30mm of hollow steel pipe, a length of 15mm.Mine tail is measured when using this device
During sand sedimentation permeance property, need below this device, connect the clear water oozed out with bucket, become with slurry face height after weighing weight in the balance
Change checking mutually, take its mean values and carry out record.
A kind of mine tailings sedimentation permeance property assay method, the method comprises the following steps:
Step one, configuration desired concn, the tailing slurry of grade composition, precalculate required accurate tailings, clear water matter
Amount；
Step 2, the tailing slurry configured uniformly is poured in mine tailings sedimentation permeance property determinator, up time
The full and uniform stirring of pin five to ten minutes, makes tailing slurry reach homogeneous fluid state；
After step 3, range estimation tailing slurry reach isotropic stable state, start to record slurry level height, tail the most in the same time
Layer of sand height, infiltration water quality；Wherein liquid level and tailings layer height use range estimation reading, and during reading, sight line is equal with liquid level, as
Really liquid level is spill, is as the criterion with the bottom of spill, if liquid level is convex, the top with convex is equal, and permeates water quality
Amount weighs weight in the balance after then being placed container access by bottom；The data logging interval time to settle according to tailings, seepage velocity spirit
Live and adjust, 5min, 10min, 30min, 1h, 2h can be divided into；
Step 4, tailings complete sedimentation and process of osmosis laggard row Data Management Analysis, draw tailings settling height, ooze
The time dependent curve of the water yield, and analytical data rule, form final research report.
Embodiment
The 65% mass concentration slip of step one, the present embodiment configuration 6000g, needs the tailings of 3900g, the water of 2100g；
Step 2, get out required rubber washer, coordinate scale paper and agitating device 2 in advance, in the present embodiment
Agitating device 2 can select stirring rod；Say that the tailing slurry configured uniformly is poured mine tailings sedimentation permeance property into and measured dress
Postponing and stir clockwise, the time is five to ten minutes, makes tailing slurry reach homogeneous fluid state；
Step 3, after tailing slurry reaches isotropic stable state, record time at that time, and proceed by data note
Record, data include slurry level height, tailings layer height and infiltration water quality；
Step 4, again tailing slurry complete sedimentation and process of osmosis laggard row Data Management Analysis, are formed and finally study report
Accuse.
Refering to Fig. 6 Figure 10, this device can carry out with the mensuration work organizing variable concentrations tailing slurry, after calculating
Again required quality clear water is added, convenient and swift.With group variable concentrations tailings determination data actual physics to be met rule,
Require to look up reason during grave fault, re-start mensuration after getting rid of error, it is ensured that measurement result accurately can use.
The data of variable concentrations tailing slurry process as shown in the table:
Table classified tailings sedimentation velocity table
