Description
Technical field
The present invention relates to a kind of mining spraying wind leaking stoppage material and preparation facilities.
Background technique
Spontaneous combustionof coal is one of Major Natural Disasters of China's coal-mine, is resulted in significant economic losses, and coal is seriously threatened
The safety of mine personnel.Caused by mine spontaneous combustionof coal is mainly leaked out as underground.Therefore, in order to efficiently prevent and treat mine coal from
Combustion, leaks out to underground and a little blocks, and reduces or prevents oxygen supply, prevent coal oxidation very crucial.In pit mining
The spontaneous combustion of coal occurs mainly in the goaf in the presence of channel of leaking out, open-off cut, stops adopting line, geological structural belt, tunnel caving place etc.
Place.It leaks 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, and thick loess grouting technology need to consume a large amount of soil, and the area of some scarce soil is not available
And slurries are easy downward seepage flow, cannot block crack；Ammonium salt gel discharges toxic and harmful gas, and colloid is easy cracking；Macromolecule
Gel is at high cost, and wind leaking stoppage effect disappears after moisture evaporation；Three-phase froth does not have intensity, and the stable time only has 8~12 small
When, solidification is not implemented, the effect of wind leaking stoppage is not had after bubble burst；Foamed resin is at high cost and to ambient temperature requirements
Height, incendivity under hot conditions；Expanding cement poor sealing effect cannot block tiny crack.
Therefore in the prior art there are no have excellent performance, stable special wind leaking stoppage material.
Summary 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
It can reliable mining spraying wind leaking stoppage material.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of mining spraying wind leaking stoppage material, weight composition
For 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 hydroxyethylmethylcellulose, 1~2 part of lauryl sodium sulfate, fatty alcohol polyoxyethylene ether
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 step is:
1): in main agitator tank be added water, flyash, fatty alcohol polyoxyethylene ether, hydroxyethylmethylcellulose, gypsum,
Cement, white lime, blender are formed uniformly pulverized fuel ash slurry；
2): adding a small amount of water and polyphosphoric acids, hydroxypropyl starch ether, redispersable latex powder to stir evenly shape in agitator
At epoxy glue mucus；
3): lauryl sodium sulfate, sodium sulfate of polyethenoxy ether of fatty alcohol being dissolved in suitable quantity of water in pill tank and being stirred
Dissolution forms solution；
4): above-mentioned solution and epoxy glue mucus is mixed into the pulverized fuel ash slurry of main agitator tank, blender with 100 ± 20 turns/
Minute rotational speed, mixing time are 3~6min, are then encapsulated into spray tank, are prepared into mining spraying wind leaking stoppage material.
Correspondingly, the present invention blocks up the preparation facilities of wind material, including main agitator tank, blender is set in main agitator tank, it is main
Closed gallery ports and mounting rack are set at the top of agitator tank, and mounting rack is used to install the motor of blender；The device packet
Agitator and pill tank are included, the agitator and pill tank are located above main agitator tank and by 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 vacuum pump by pipeline.
Beneficial effects of the present invention: the present invention is using fatty alcohol polyoxyethylene ether, hydroxyethylmethylcellulose as surface
Activating agent enables to pulverized fuel ash slurry solid phase particles evenly dispersed, facilitates stable system, and facilitates aerated fluid thin
Seepage flow in rimala.Based on lauryl sodium sulfate and sodium sulfate of polyethenoxy ether of fatty alcohol, fatty alcohol polyoxyethylene ether, hydroxyl second
The organised surfactant systems of ylmethyl cellulose synergistic effect can provide superior foams performance, when system material passes through
Hitting during spray head sprays and with mine palisades when the of short duration process contacted is contacted with air can produce abundance
Bubble.And it not will increase bubble because dissolving and stirring at low speed mixing in batches in process.Polyphosphoric acids, hydroxypropyl form sediment
Organic gluing system that powder ether, redispersable latex powder are constituted, which is capable of providing, stablizes quick glueability, can be realized seepage flow
Stable leak stopping barrier is quickly formed in 20min at room 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 gypsum, cement, white lime dosage increase foaming effect difference later or be difficult to bubble,
Flyash dosage is larger；But flyash dosage directly results in the resistance to compression of material, adhesive property reduces the present invention and passes through compound bubble
With the foundation of organic system, this problem in the prior art is successfully solved.
Process flow is simple on the whole, foams performance is excellent by the present invention, and compound foaming agent reduces cost, in spraying process
It is contacted with air and generates enough bubbles, coefficient of foaming is high, compression strength is big, high temperature resistant and heat-proof quality are good.And aerated fluid seeps
Permeability can be good, and solidification is quick, the time can pass through three kinds of gluing material amounts appropriate adjustments.Use rear wind leaking stoppage significant effect, resistance
It fires, is antistatic.It is entire cheap, it is at low cost；It can also be right by reinforcing stirring to obtain foam in the case where that can not spray
Crack or hole leak stopping are coated afterwards, have in terms of coal mine and coal-field fire ground crack closure and value is widely used.
