Description
Technical field
The present invention relates to a kind of mining spraying wind leaking stoppage material and preparation facilities.
Background technology
Spontaneous combustionof coal is one of Major Natural Disasters of China's coal-mine, causes great economic loss, seriously threatens coal
The safety of ore deposit personnel.Mine spontaneous combustionof coal leaks out what is caused mainly due to underground.Therefore, in order to efficiently prevent and treat mine coal certainly
Combustion, leaks out to underground and a little blocks, and reduces or prevent oxygen supply, prevents coal oxidation very crucial.In pit mining
The spontaneous combustion of coal occurs mainly in the presence of the goaf of passage of leaking out, open-off cut, stops adopting line, geological structural belt, tunnel caving place etc.
Place.Leaked out to effectively block underground coal mine, the country is frequently with grouting, gel, foamed resin, three-phase froth, expanding cement
Deng.But these methods all come with some shortcomings, thick loess grouting technology need to consume a large amount of soil, and the area of some scarce soil cannot use
And the easy seepage flow downwards of slurries, it is impossible to block crack；Ammonium salt gel discharges toxic and harmful, and colloid is easily cracked；Macromolecule
Gel high cost, wind leaking stoppage effect disappears after moisture evaporation；Three-phase froth does not have intensity, stabilization time only have 8~12 it is small
When, solidification is not implemented, once the effect that wind leaking stoppage is not had after bubble burst；Foamed resin high cost and to environment temperature requirement
Height, incendivity under hot conditions；Expanding cement sealing effectiveness is poor, it is impossible to block tiny crack.
Therefore in the prior art also without excellent performance, stable special wind leaking stoppage material.
The content of the invention
Technical problem solved by the invention is to provide based on a kind of inorganic raw material formula, easy to use, mechanical property
Can reliable mining spraying wind leaking stoppage material.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of mining spraying wind leaking stoppage material, weight composition
It is 100 parts of water, 13~25 parts of flyash, 6~8 parts of gypsum, 20~26 parts of cement, 8~12 parts of white lime, aliphatic alcohol polyethenoxy
0.5~0.8 part of ether, 0.4~0.8 part of HEMC, 1~2 part of lauryl sodium sulfate, AEO
1~1.2 part of sodium sulphate, 1.8~2.5 parts of polyphosphoric acids, 1.6~2 parts of hydroxypropyl starch ether, the vinegar that viscosity is 600~800mPas
0.8~1.2 part of the redispersable latex powder of sour ethylene-vinyl copolymer type.
Preparation process is：
1）：In main agitator tank add water, flyash, AEO, HEMC, gypsum, cement,
White lime, agitator is formed uniformly pulverized fuel ash slurry；
2）：A small amount of water and polyphosphoric acids, hydroxypropyl starch ether, redispersable latex powder is added to stir to form mixed in agitator
Rubber alloy mucus；
3）：Stirring and dissolving during lauryl sodium sulfate, sodium sulfate of polyethenoxy ether of fatty alcohol are dissolved in into suitable quantity of water in pill tank
Form solution；
4）：Above-mentioned solution and epoxy glue mucus are mixed into the pulverized fuel ash slurry of main agitator tank, agitator is with 100 ± 20 revs/min
Rotational speed, mixing time is 3~6min, is then encapsulated into spray tank, is prepared into mining spraying wind leaking stoppage material.
Accordingly, the preparation facilities of the stifled wind material of the present invention, including main agitator tank, sets agitator in main agitator tank, main
Agitator tank top sets closed gallery ports and mounting bracket, and mounting bracket is used to install the motor of agitator；Described device bag
Agitator and pill tank are included, the agitator and pill tank are located at main agitator tank top and pass through pipeline and valve and main agitator tank
Connection；Agitating paddle is set in the agitator, and agitating paddle is driven by motor.
Preferably, the main agitator tank connects vavuum pump by pipeline.
Beneficial effects of the present invention：The present invention is using AEO, HEMC as surface
Activating agent enables to pulverized fuel ash slurry solid phase particles dispersed, contributes to stable system, and contribute to aerated fluid thin
Seepage flow in rimala.Based on lauryl sodium sulfate and sodium sulfate of polyethenoxy ether of fatty alcohol, AEO, hydroxyl second
The organised surfactant systems of ylmethyl cellulose synergy can provide superior foams performance, when system material passes through
Abundance is produced by when clashing into the of short duration process for contacting with air contact during shower nozzle sprays and with mine palisades
Bubble.And will not increase bubble because dissolving in batches and stirring at low speed mixing in process.Polyphosphoric acids, hydroxypropyl form sediment
The organic gluing system that powder ether, redispersable latex powder are constituted can be provided stablizes quick glueability, can realize seepage flow
The quick leak stopping barrier for forming stabilization in 20min at ambient temperature after dispersion.The composite solid that cement, gypsum, white lime are constituted
Phase system promotes the hydration reaction of flyash so that solid matter rapid curing, foam compressive property is excellent.
In the prior art because foaming effect is poor after gypsum, cement, the increase of white lime consumption or is difficult to bubble,
Flyash large usage quantity；But flyash consumption directly results in the resistance to compression of material, the adhesive property reduction present invention by being combined bubble
With the foundation of organic system, this problem in the prior art is successfully solved.
Technological process on the whole of the invention is simple, foams performance is excellent, foaming agent reduces cost is combined, in spraying process
Enough bubbles are produced with air contact, coefficient of foaming is high, compression strength is big, high temperature resistant and heat-proof quality are good.And aerated fluid oozes
Permeability can be good, and solidification is quick, the time can suitably be adjusted by three kinds of gluing material amounts.Use rear wind leaking stoppage effect is significant, resistance
Combustion, it is antistatic.Whole cheap, low cost；Can also be right by strengthening stirring acquisition foam in the case where that cannot spray
Crack or hole leak stopping are coated afterwards, are had in terms of colliery and coal-field fire ground crack closure and are widely used value.
