Description
Technical field
The present invention relates to mill tailings depositary management reason technical field more particularly to a kind of Tailings Dam dust suppression liquid and dust suppression construction party
Method.
Background technique
Gold tailing pond does beach in dry season or wind season by generating region property dust pollution question, due to Tailings Dam major function
It is mine tailings to be arranged in storage metal mine production process and by natural filtration recycling ring water for selecting factory to be recycled, Tailings Dam packet
Dam body, Gan Tan, water catchment area are included, wherein dry beach is all that mill tailings natural sedimentation is formed, will form dust in dry season or wind season
Pollution problem, the dust-suppression method of present comparative maturity are the sprinkling dust suppressant solidification surface Gan Tan and watering dust suppression method.Spray dust suppression
Agent anti-dust effect is preferable, but dry beach face product is big, and dynamic ore drawing, and ore drawing will fail again after dust suppressant solidification, so
The Tailings Dam for having closed library is applicable in, dust suppressant is not only at high cost, but also after tailing closing relative to soil also not environmentally, therefore
Need to find a kind of more cheap material for solidifying the surface Gan Tan.The shortcomings that dust suppression method of sprinkling water is that spray area is big, up-front investment
Expensive, later maintenance cost is big, and dam facing constantly increases, and watering pipeline periodically also needs to raise, and is largely applicable in library
Interior water, influences water return amount in library, and this method is also very big for the waste of water.
In addition, dry sand of tailings reservoir area is big, first is that, since the dam beach Nei Gan is the part high-land close to dam body, close to remittance
The dry beach gesture in pool is low, and ore pulp is flowed along topography after ore drawing, forms zanjon, and ore pulp flows in ditch, and it is non-to cover dry beach face product
Often small, 85% or more dry beach can not be covered by ore pulp, and the dam beach Nei Gan fugitive dust is serious.Second is that beach is done by ore pulp covering part, due to
Mortar retention time is short, shallow under water penetration to the surface layer Gan Tan, so dirt has been dried after ore drawing again soon, in spring, autumn
Dry winds season is waited, beach sunning is done after general ore drawing and begins to play dirt again within 2 days or so.Therefore, as can choosing suitable region spray
It spills, avoids repeating being also to save sprinkling material and artificial effective measures.
Summary of the invention
The present invention in view of the above shortcomings of the prior art, provide it is a kind of convenient for materials, it is cheap and convenient for construction suppression
Dirt liquid.
The technical scheme to solve the above technical problems is that a kind of Tailings Dam dust suppression liquid, which is characterized in that including
Tailings liquid, the grains of sand and biomass fiber material, the weight ratio of the tailings liquid, the grains of sand and biomass fiber material are 100:(3-
10):(1-10).Physical mixed stirs evenly to form the dust suppression liquid.
The beneficial effects of the present invention are: tailings liquid and a small amount of grains of sand and biomass fiber material easily obtain,
Since the addition of the grains of sand can suitably increase the specific gravity of dry beach surface material, floatability with the wind is reduced；Biomass fiber then increases
The caking property on surface and hardened ability, comprehensive utilization can be to significantly improving in dry beach wind resistance energy, and the materiel machining holds
Easily, cheap, it is sprayed relative to traditional viscose glue, will be greatly reduced depositing dust cost.
Based on the above technical solution, invention can also do following improvement.
Further, the biomass fiber material is the fiber pipe nipple of hay or stalk by cutting, the length of the pipe nipple
Degree is 20-50 millimeters.
Further, the partial size of the shown grains of sand is 80-200 mesh.
Further, the stalk is Wheat Straw or rice straw.
Beneficial effect using above-mentioned further scheme is to choose the reasonable partial size of the grains of sand and fibrous material reasonable length, energy
It is rationally taken into account in terms of improving the hardened ability in the surface Gan Tan and conveniently pumping sprinkling.
Additionally, it is preferred that Wheat Straw or rice straw, and cutting processing is used, and it can guarantee the cylinder shape characteristic of stalk, and it is common
Crushing and processing then cannot be guaranteed that hollow stalk is complete.In stirring, slurries and the grains of sand can enter in stalk cylinder, and then form one
Body is avoided since stalk specific gravity is too small without merging.
The invention also discloses a kind of Tailings Dam dust suppression construction methods, including mobile flusher, and steps are as follows:
1) grains of sand and 10-50 millimeters of fiber pipe nipples for preparing 80-200 mesh, by weight for 100:(3-10): (1-10's)
Ratio stirs evenly tailings liquid, the grains of sand and fiber pipe nipple addition agitator tank；
2) mixed liquor in stirring is pressurizeed by slush pump, and the nozzle by connecting with slush pump is sprayed onto
The region Gan Tan；
3) with the beach face after round roller rolling sprinkling.
Method beneficial effect of the invention is: " the shortcomings that watering dust suppression method is first is that avoided using mobile flusher
Spray area is big, and up-front investment is expensive, and later maintenance cost is big, and dam facing constantly increases, and watering pipeline periodically also needs
Raise " the shortcomings that；Second is that spraying in stirring, be conducive to the abundant fusion of mixed liquor；Third is that compared under dust suppressant dust suppression cost
Drop, two exogenous substances fibers are more environmentally friendly.
Based on the above technical solution, invention can also do following improvement.
It further, further include delimiting sprinkling region, the slime dam neighboring area specially formed after each ore drawing slurry is sprayed
It spills.
Beneficial effect using above-mentioned further scheme be put Tailings Slurry every time it in center form depression or puddle, and
Then slowly desiccation forms dry beach on periphery, region of making rational planning for, can be with the accumulation of Tailings Dam, disposably to dry beach surface cure
Processing, avoids the repetition of blindness from spraying.
Further, shown mobile flusher, agitator tank, slush pump including flat car and on the flat car,
Power device, nozzle strut, pipeline and nozzle, the pipeline successively connect agitator tank, slush pump and nozzle, and the nozzle is set
In nozzle strut upper end, the nozzle strut is telescopic arms, is set on the flat car by rotatable chassis.
