Description
Technical field
The present invention relates to a kind of foam mortar, is used for filling in mine more particularly, to a kind of, with mine tailing as primary raw material
Foam mortar, not only can be widely used in filling in mine mining technique, it may also be used for municipal administration, processing and construction of construction material etc.
Field.
Background technology
Foam mortar is, with physical method, foaming agent water solution is prepared into foam, and key component includes that cement base coagulates material
Material, water and optional component are gathered materials, admixture, additive are mixed according to the ratio of certain ratio, and made through physical chemistry
A kind of light material formed with hardening.
At present both at home and abroad the filler of filling in mine many using tailings, gather materials, the aggregate such as rubble, add a certain proportion of
Cementing material, such as cement, flyash, steel quarrel etc., stir to form certain density filling slurry or lotion together with water, to flow automatically
Or the form of pump pressure is transported to stope, but all there is the defect of itself to some extent.Gravity flow tailings filling body is by deadweight
No pressure conveying is carried out by pipeline, the subject matter of the filling process is that filling pipe abrasion is big, filling slurry is susceptible to isolation,
The problems such as layering, make that strength of filling mass is low, change is big, often can not meet the strength of filling mass of stope design;Meanwhile, filling is adopted
Field produces substantial amounts of bleed (including flushing pipe water), not only pollutes stope environment, and makes Tight filling bad, reduces
Filling effect.High dense fill (lotion) can reduce filling stope water pollution, and with preferable Tight filling, but paste body filling is deposited
In two problems:One be paste body filling be pump pressure conveying, need to introduce a set of pump pressure conveying equipment, system process is complicated, expense
Higher;Two is that pumping lotion plugging phenomenon often occurs.Plugging processes very difficult once occur to which, not only affects normal
Filling process, and process plugging to pay hardships work and great number cost.
In recent years, people increasingly pay attention to the improvement to method of mining by the way of filling filling process, and foam mortar filling body technique is just
It is one of which.Foam mortar obturation be by concrete, gather materials (including thin Gobi aggregate, thin river sand, rod milling sand, flyash,
Tailings etc.), water, foaming agent formed foam carry out being well mixed stirring, Jing Guoyi with appropriate additive in certain proportion
The physics chemical action of section time, formed after dry hardening to be drained off containing certain ratio space, with some strength
Filling new material.《Metal mine》In " Research on Application Value of foam mortar obturation " text that 10th phase in 2013 delivers,
In order to obtain more preferable filling effect and cost-effective, can only be improved from filler.Through many-sided contrast,
And other mine experiences are used for reference, here selects foam mortar as filler.Selected material be cement, natural sand, water,
Foaming agent etc..The expense that the expense filled by foam mortar is filled with conventional slurry is compared, it can be seen that foam is filled
Technology has very high economic benefit.But the material selected in this article is cement, natural sand, cost times is so higher, simply than normal
Rule mortar carries out filling economical.
Content of the invention
The purpose of the present invention is aiming at the problem of the problems referred to above of prior art presence, and provide a kind of raw material simple,
The tailing foam mortar of underground mine exploitation filling easy to make, with low cost.
For realizing that the above-mentioned purpose of the present invention, a kind of tailing foam mortar of underground mine exploitation filling of the invention are adopted
Technical scheme below:
A kind of tailing foam mortar of underground mine exploitation filling of the present invention is by cement, mine tailing, quick lime, high alumina water
Mud, gypsum, water are prepared from by the foam that foaming agent is formed through stirring mixing, injection, each component of the total amount by 100% timing
Weight/mass percentage composition is:
Each component weight/mass percentage composition is preferably:
Each component weight/mass percentage composition is more preferably:
Described Portland cement is greater than or equal to P.O32.5 Portland cements.
The granularity of the mine tailing is 0.074~3mm grain size contents 90%, and wherein 0.1~3mm grain size contents 60% are
Preferably;In order to improve obturation compression strength, described mine tailing particle size range accounts for more than 90% with 0.25~3mm and is preferred.
Described quick lime be CaO content 85%, and quick lime through levigate to granularity be -0.074mm contents 90%,
It is preferred with -0.074mm contents 95%.
It is raw material that the alumina cement is bauxite and lime, prepares by a certain percentage, through calcining, levigate obtained one
Plant the hydraulic cementing materials with aluminate as main mineral constituent.
Described gypsum is gypsum, and main component is CaSO4·2H2O.
Described foaming agent is vegetalitas macromolecule foaming agent.Such as the limited public affairs of Thailand of Linyi City Hedong District section energy-saving building material machinery
The vegetalitas macromolecule foaming agent of department's production, the foaming agent import high-quality natural plants macromolecular material is raw material, through one is
The complicated chemical reaction of row is generated, and product is in lurid pure transparent oily liquid, nontoxic, tasteless, nothing insensitive to hard water
Sediment, pH value are close to neutrality, to cement and metal non-corrosiveness, do not produce pollution to environment.Other manufacturer productions can also be used
Vegetalitas cement blowing agent, such as Thailand of section cement plant foaming agent.
Described water is common running water or mine water, ore dressing recirculated water.
Described tailing foam method for preparing mortar is:By Portland cement, mine tailing, quick lime, alumina cement, stone
Cream, water sequentially add mechanical agitation uniformly, then introduce a foam into mortar, and mechanical agitation is uniform.
Vegetalitas macromolecule foaming agent of the present invention, by the method for compressed air, makes foaming agent solution and quilt
The air of compression makes mixture pass through a special foaming cylinder, most in the indoor mixing of mixing then under compressed air effect
End form is introduced in mortar into foam.
Compared with prior art, a kind of advantage of the tailing foam mortar of underground mine exploitation filling of the invention exists
In:
(1) in the foam mortar by mine tailing for main component of the present invention, the utilization rate of mine tailing has reached more than 50%,
And at present existing filler many using tailings, gather materials, the aggregate such as rubble, therefore foam mortar of the invention is with low cost,
In filling construction, economic benefit can be increased substantially.
(2) in the foam mortar by mine tailing for main component of the present invention, due to introducing foam, therefore make it have
Flow well, pipeline is not blocked in pipeline.At present in the course of conveying of filler, the blocking and abrasion of pipeline
Problem is not also solved well, and the foam in foam mortar has lubrication well and drag reduction to act on, and can improve well
Transport condition.
(3) in the foam mortar in the present invention by mine tailing for main component, with good education resistance.Conventional filling material
In material stowing operation, usually segregation phenomenon can occur, not only result in water pollution, and after causing filler hardening intensity is not
Enough uniform, affect filling effect.And the education resistance of tailing foam mortar can make filling even intensity, it is to avoid water pollution stope ring
Border.
(4) in the foam mortar in the present invention by mine tailing for main component, with higher concentration and education resistance, therefore
Its connect top effect better than conventional filler, almost 100%.
