Technical field
The invention belongs to underground coal mine coal spontaneous combustion Treatment process field, particularly prevent and treat inhibition foam material of coal spontaneous combustion and preparation method thereof.
Background technology
In process of coal mining, contact with air after having the coal seam of spontaneous combustion tendency to be broken, be oxidized at normal temperatures, produce heat and its temperature is raised, if can not administer in time, coal body spontaneous combustion can be caused.The spontaneous combustion of coal threatens the safety of coal production and storage always, not only causes coal resources to lose, even can cause mine gas explosion or underground fire, causes casualties and huge property loss.The coal that China's degree of coalification is low is more, and the probability that under mine, coal spontaneous combustion fire occurs is comparatively large, so the preventing and controlling of mine coal body spontaneous combustion are extremely important.
Inhibition foam material control coal spontaneous combustion technology utilizes to carry the foam stronger with suspending power as carrier, retardant is transported to pending region, foam containing retardant can surround the fissure-plane of coal body and coal body, play moisturizing heat absorption, the effect of starvation, thus reduce the oxidation rate of coal when low temperature, extend the spontaneous combustion time of coal.Inhibition foam material control coal spontaneous combustion technology and grouting prevent and treat coal spontaneous combustion technology and colloidal materials and prevent and treat coal spontaneous combustion technology to compare supplies consumption few, process implementing is simple and convenient, to burst the potential safety hazard such as slurry, running pulp, good fluidity can cover coal body face uniformly, and the effect of control coal spontaneous combustion is more obvious.Existing inhibition foam material category is more, but the part that still comes with some shortcomings.Such as application number be 200910116090.X patent discloses a kind of compound inhibition foam material be jointly made up of chemical retardant and physics retardant, this compound inhibition foam material flowability is good, coal body face can be covered more uniformly during application, higher to the resistance efficiency of coal body, the effect of long-time control coal spontaneous combustion can be reached, but containing oxidant in this inhibition foam material, there is certain potential safety hazard.So the control coal spontaneous combustion inhibition foam material existed at present also needs to improve the requirement that could meet mine control coal spontaneous combustion.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the present invention proposes a kind of inhibition foam material preventing and treating coal spontaneous combustion and preparation method thereof.After a kind of inhibition foam material preventing and treating coal spontaneous combustion of the present invention passes through foaming, be that target retardant and reinforcing agent can be transported to complicated processing region by carrier well with foam, the inhibition foam produced serves the effect of multiple oxygen barrier resistanceization to coal body spontaneous combustion, reach the object of control coal spontaneous combustion.
A kind of inhibition foam material preventing and treating coal spontaneous combustion of the present invention, is characterized in that the reinforcing agent of the retardant of the thickener of the foaming aids of the blowing agent containing mass percent 0.5-10%, 0.2-3%, 0.02-0.5%, 0.5-5%, 2.5-15%, the water of 66.5-96.28%.A kind of preparation method preventing and treating the inhibition foam material of coal spontaneous combustion of the present invention, it is characterized in that by mass percentage by the water mixing and stirring of the reinforcing agent of the retardant of the thickener of the foaming aids of the blowing agent of 0.5-10%, 0.2-3%, 0.02-0.5%, 0.5-5%, 2.5-15%, 66.5-96.28%, namely obtain a kind of inhibition foam material preventing and treating coal spontaneous combustion of the present invention.
Described blowing agent be selected from sodium sulfate of polyethenoxy ether of fatty alcohol, APG, fatty acid methyl ester sulfonate, SS-161, GNS, α-sodium olefin sulfonate, lauryl alcohol phosphate potassium one or more;
Described foaming aids be selected from DDAO, Cocoamidopropyl betaine one or more;
Described thickener be selected from polyacrylamide, carboxymethyl cellulose, CMS one or more;
Described retardant be selected from calcium chloride, magnesium chloride, sodium chloride one or more;
Described reinforcing agent be selected from swell soil, montmorillonite, flyash, kaolin one or more.
Compared with prior art, the invention has the beneficial effects as follows:
1, the foam that described a kind of inhibition foam material preventing and treating coal spontaneous combustion produces can form fine and close covering layer, starvation on coal body surface, forms first floor overcoat; The wettable coal body of moisture in foam, absorbs heat, reduces the heat accumulation of coal, forms second layer overcoat; After lather collapse, reinforcing agent is released and covers coal body face, starvation, forms third layer overcoat; After lather collapse, retardant is also released, and the moisture absorbed in air forms liquid film and is enclosed in coal body face, and oxygen barrier is absorbed heat, and forms the 4th layer of overcoat.
2, described a kind of inhibition foam material preventing and treating coal spontaneous combustion extends the time of effectively control coal spontaneous combustion, adds the efficiency of control coal spontaneous combustion, reduces the probability of spontaneous combustion of coal, reaches the object of control coal spontaneous combustion.
3, described a kind of inhibition foam material preventing and treating coal spontaneous combustion decreases by soil amount, and cost is low, easy to use, and construction technology is simple, and nontoxic non-corrosiveness, health and the coal texture of workman can not be damaged.
