Abstract
The invention discloses a kind of sealing material of the gas extraction hole be made up of sulphur plaster of Paris, flyash, lime, wilkinite and metakaolin.Because desulphurization building gypsum is formed by desulphurization gypsum calcination, when adding water, meeting and flyash, lime and metakaolin generate a large amount of ettringite, and form reticulated structure, make slurry very rapid hardening, and produce intensity, and wilkinite falls into water body by volcanic ash is formed, and is a kind of natural nano-material, be filled in above-mentioned reticulated structure, serve good sealing process.
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 run in mining activity.Gas extraction hole is the effective ways solving gas problem, but the sealing of hole problem of gas extraction hole is a thorny problem always.If adopt silicate cement sealing of hole, shrink due to during silicate cement consolidation, make sealing of hole operation failure; If adopt aluminate cement sealing of hole, because inside during aluminate cement consolidation can produce some tiny cracks, closed material was lost efficacy; If adopt chemical pulp sealing of hole, cost is too high on the one hand, and chemical pulp is inflammable on the other hand, there is downhole safety hidden danger, neither a kind of desirable sealing material.
Summary of the invention
The object of the invention is to provide a kind of sealing material making method for gas extraction hole, and it can solve problem existing in background technology effectively.
This sealing material is made up 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 object powder;
2, sulphur plaster of Paris, flyash, lime, wilkinite and metakaolin after processing are proportionally mixed, to obtain final product.
Owing to have employed above technical scheme, the present invention has following beneficial effect: because desulphurization building gypsum is formed by desulphurization gypsum calcination, when adding water, meeting and flyash, lime and metakaolin generate a large amount of ettringite, and form reticulated structure, make slurry very rapid hardening, and produce intensity, and wilkinite falls into water body by volcanic ash is formed, be a kind of natural nano-material, be filled in above-mentioned reticulated structure, serve good sealing process.
Embodiment
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below the technical scheme in the embodiment of the present invention being clearly and completely described.
This embodiment is achieved by the following technical solutions, and it is made up 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 object powder;
2, sulphur plaster of Paris, flyash, lime, wilkinite and metakaolin after processing are proportionally mixed, to obtain final product.
During use, by water and sealing material in 0.5: 1 ratio stir and can use.
Owing to have employed above technical scheme, the present invention has following beneficial effect: because desulphurization building gypsum is formed by desulphurization gypsum calcination, when adding water, meeting and flyash, lime and metakaolin generate a large amount of ettringite, and form reticulated structure, make slurry very rapid hardening, and produce intensity, and wilkinite falls into water body by volcanic ash is formed, be a kind of natural nano-material, be filled in above-mentioned reticulated structure, serve good sealing process.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art should be appreciated that it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
