Abstract
The invention discloses hole sealing material for a gas drainage hole, which comprises sulfur building plaster, coal ash, lime, bentonite and metakaolin. As desulfurization building plaster is formed by calcining desulphurization plaster, the desulfurization building plaster generates a large amount of ettringite with the coal ash, the line and the metakaolin when water is added, and net structures are formed, so that slurry is quickly hardened, and the strength is generated; and the bentonite which is formed by dropping volcanic ash in water is a natural nanometer material, and is filled in the net structures, so as to achieve excellent sealing effect.
Description
Technical field
What the present invention relates to is mining material use technical field, is specifically related to a kind of sealing material making method for gas extraction hole.
Background technology
Gas is the maximum technical barrier that runs in the mining activity.Gas extraction hole is the effective ways that solve the gas problem, but the sealing of hole problem of gas extraction hole is a thorny problem always.If adopt the silicate cement sealing of hole, because silicate cement shrinks when fixed, make sealing of hole operation failure; If adopt the aluminate cement sealing of hole, can produce some tiny cracks because aluminate cement is inner when fixed, closed material was lost efficacy; If adopt the chemical pulp sealing of hole, cost is too high on the one hand, and chemical pulp is inflammable on the other hand, has downhole safety hidden danger, neither a kind of desirable sealing material.
Summary of the invention
The object of the invention provides a kind of sealing material making method for gas extraction hole, and it can solve existing problem in the background technology effectively.
This sealing material is comprised of sulphur plaster of Paris, flyash, lime, wilkinite and metakaolin.
The composition range of this sealing material is:
The preferred component scope of this sealing material is:
The optimal components scope of this sealing material is:
The manufacture method of this sealing material is:
1, sulphur plaster of Paris, flyash, lime, wilkinite and metakaolin are processed into respectively fineness and are not less than 200 purpose powder;
2, sulphur plaster of Paris, flyash, lime, wilkinite and the metakaolin after will processing proportionally mixes, and get final product.
Owing to having adopted above technical scheme, the present invention has following beneficial effect: because desulphurization building gypsum is formed by desulphurization gypsum calcination, meeting and flyash, lime and metakaolin generate a large amount of ettringite when adding water, and the formation reticulated structure, make very rapid hardening of slurry, and produce intensity, and falling into water body by volcanic ash, wilkinite forms, be a kind of natural nano-material, filling has been played good sealing process in above-mentioned reticulated structure.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, the below is clearly and completely described the technical scheme in the embodiment of the invention.
This embodiment is to be achieved by the following technical solutions, and it is comprised of sulphur plaster of Paris, flyash, lime, wilkinite and metakaolin, and its composition range is:
The manufacture method of sealing material is:
1, sulphur plaster of Paris, flyash, lime, wilkinite and metakaolin are processed into respectively fineness and are not less than 200 purpose powder;
2, sulphur plaster of Paris, flyash, lime, wilkinite and the metakaolin after will processing proportionally mixes, and get final product.
During use, water and sealing material can be used in 0.5: 1 ratio stirring.
Owing to having adopted above technical scheme, the present invention has following beneficial effect: because desulphurization building gypsum is formed by desulphurization gypsum calcination, meeting and flyash, lime and metakaolin generate a large amount of ettringite when adding water, and the formation reticulated structure, make very rapid hardening of slurry, and produce intensity, and falling into water body by volcanic ash, wilkinite forms, be a kind of natural nano-material, filling has been played good sealing process in above-mentioned reticulated structure.
It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art should be appreciated that it still can make amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.
Claims (2)
