Description
Technical field
The invention belongs to tailing water clarification technique fields, and in particular to a kind of clarification system for Tailings Dam tail water, it is special
During Shi Yongyu use not run because Tailings Dam depth distance shorter, drainage point with arrange tail point be closer, tailings particles it is meticulous
It causes water quality to be difficult to clear Tailings Dam, realizes Tailings Dam tail water short distance clarification, it is ensured that tailings storage backwater tapered water quality meets normal
Production or outlet need.
Background technique
Tailings Dam is the critical facility of bargh, needs constantly to arrange into tailing Kuku during the normal production run in mine
Put the byproduct Tailings Slurry of mineral processing production.Tailings Slurry contains large quantity of moisture, accounts for about Tailings Slurry 60%~70%, Tailings Slurry internal solid
Tailing precipitates in Tailings Dam, and Tailings Slurry water body part is transmitted back to dressing plant by drainage point after clarifying in library and carries out circulation benefit
With or outlet.
At present because ore-dressing technique progress makes storage tailings particles attenuate, the clarification distance that water body needs is continuously increased, and
Most domestic Tailings Dam is in use, the later period, and tailrace clarification distance shortens year by year, and return water water quality deterioration produces mineral processing production
Adverse effect is given birth to, while clear tail water outlet completely does not produce pollution to surrounding enviroment yet.Tailings Dam tail water short distance
Clear system is to ensuring that mine normally produces and reservoir area surrounding enviroment is protected to have important practical significance.
For Tailings Dam tailrace clarification, improve it is tailings storage backwater tapered and it is outer draining water quality currently without system solution,
Disposal Measures mainly have two kinds: one is Tailings Dam reservoir level is promoted, allowing tail water to be accumulated in tailing Kuku for a long time, when passing through
Between effect extend the sedimentation time and improve water quality；Another kind is to be shortened in tail water by addition chemical agent method (flocculant) admittedly
The sedimentation time of body particle.
It is found in practical application, there are the following problems for existing method:
(1) it promotes Tailings Dam reservoir level and extends tail water depot accumulation time, Tailings Dam reservoir capacity for flood control will be occupied, it is anti-to Tailings Dam
Big vast safety is unfavorable；
(2) it raises reservoir level and in a disguised form shortens length of dry sand of tailings reservoir, so that saturation is raised, to safety of dam body stability
It is unfavorable.
(3) although chemical method can effective flocculate solids particle, incidentally increase the chemical component in tail water, outside
Adverse effect is generated to surrounding enviroment after row.
(4) chemical method needs largely to use flocculant, and fringe cost is larger, because tailing amount is during ore-dressing practice
Variable, production process are difficult to accurately control additive amount.
Summary of the invention
In order to overcome drawbacks described above existing for existing Tailings Dam tailrace clarification technology, the present invention provides a kind of for Tailings Dam
The clear system of tail water short distance, be applied to during operation use because the Tailings Dam depth shorter, drainage point of distance and row's tail point away from
It causes water quality to be difficult to clear Tailings Dam from compared with close, tailings particles are meticulous, is able to achieve Tailings Dam tail water short distance clarification, will not produce
Raw additional environmental pollution.
Above-mentioned purpose to realize the present invention, the present invention it is a kind of for the clear system of Tailings Dam tail water short distance use with
Lower technical solution is realized:
Of the invention a kind of for the clear system of Tailings Dam tail water short distance, it is by being located at tailing dam and Tailings Dam
Return water/pumping equipment entrance between overfall dam of blocking, water filter combination constitute, and close to Tailings Dam return water/
Pumping equipment inlet location is laid；The overfall dam of blocking is equipped with the overflow port flowed into for Tailings Dam tail water, overflow of blocking
Dam blocks the coarse granule in tail water outside dam, and relatively clear tail water is excessive to blocking by the overflow port overflow for overfall dam of blocking
It flows in dam；The water filter is made of bracket, buoyancy tube, hook, hanging rod, geotextiles, extension recombination, described
Buoyancy tube is two, and the both ends of buoyancy tube are connect with the massif of tailing Kuku tail two sides, and bracket is mounted on two buoyancy tubes,
Bracket is linked up with equipped with 2~6 rows, and hanging rod is installed on every row's hook, and hanging rod mounts geotextiles, and the bottom of geotextiles, which is equipped with, hangs weight；
Water filter carries out anti-filter to the overflow port overflow through overfall dam of blocking to the relatively clear tail water blocked in overfall dam
It is clarified with pressure, it is ensured that filtered tail water meets production and outlet requires.
In a particular application, overfall dam of blocking first is built, then lays water filter；Overfall dam of blocking using block stone,
Cemented rock composition.The overfall dam of blocking is located at return water/pumping equipment entrance outer rim 50~120m model of tailing Kuku tail
Build is enclosed, return water/pumping equipment 10~45m of entrance outer rim that the water filter is located at tailing Kuku tail lays, blocks
The spacing kept off between overfall dam and water filter is 20~90m.
Cemented rock is all laid with close to two sides, the bottom surface of row tail region side and overflow port in the overfall dam of blocking
Veneer, to protect overfall dam of blocking.
In order to reduce the speed that tail water flows to geotextiles, protect geotextiles from the damage of water impact, the two of bracket
It holds and is equipped with porous plate close to the outside of buoyancy tube, porous plate lower end is arranged in 1.0~1.8m of pure and turbid liquid line of demarcation or less, porous plate
Also fixed function is played to bracket and buoyancy tube, so that bracket, buoyancy tube, porous plate is fixed as an overall structure, to improve water
The stability and service life of matter filter device；The geotextiles are arranged in turbid and sediment deposit line of demarcation or more.
The bracket is preferred using aluminium alloy post, and the porous plate is advisable using punching aluminium alloy plate, Ji Nengman
Sufficient intensity requirement, and be conducive to mitigate the weight of water filter.
The cemented rock veneer uses 450~550mm thickness cemented rock veneer.
To meet water filtration requirement, and use cost is taken into account, the geotextiles are preferred with 3~4 rows, the rule of geotextiles
Lattice are 350g/m2It is advisable.
One kind of the invention after the above technical solution is adopted, has following product for the clear system of Tailings Dam tail water short distance
Pole effect:
(1) system can check the solid particle in tail water to return water/pumping equipment entrance migration, and to thin in tail water
Grade gangue solids particle further filters, and tailrace clarification is made in short distance.
(2) system is being blocked on overfall dam equipped with overflow port, can carry out dam heightening as Tailings Dam reservoir level increases,
The solid particle migration in tail water is checked to the maximum extent.
(3) the tail water filter device that the system uses can rise under buoyancy automatically as Tailings Dam reservoir level increases
Height effectively filters fine fraction gangue solids particle, reduces labor workload.
(4) for the system using overfall dam is blocked and tail water filter device synthesis plays a role, safety and reliability are high, low
Cost and later period other security risks will not be generated, additional environmental pollution will not be generated, be able to satisfy Tailings Dam tail water short distance
Clear needs.
(5) water filter that the system uses, manufacturing cost is cheap, and operating cost is low, and geotextiles replacement is convenient.
