The mining filling material is prepared from the cementing material, coal ash and/or coal gangue. The raw materials for making the mining composite cementing material are wide in resource and low in cost, the prepared cementing material is adjustable in coagulation time and compressive strength, and the mining filling material prepared from the mining composite cementing material, the coal gangue and the coal ash in a mixed mode can meet the requirement for long-distance pumping and can meet the requirements of different kinds of underground filling engineering.
Description
Technical field
The present invention relates to goaf filling field, specifically, relate to a kind of mining complex cement agglutinate and filler for mine material.
Background technology
Coal is the main primary energy source of China, and current coal in China is produced and mainly relied on pit mining, and a large amount of chamber, tunnel and stope, worked-out section are dug in down-hole.Along with the extensive application of filling mining, gob-side entry retaining, support with backfilling, fire dam construction, supporting pier stud etc., requirements at the higher level are proposed to the performance of cement inorganic materials, price, require compaction material draw materials extensive, cheap, be convenient to pumped downhole, good mechanical property, the feature such as setting rate is adjustable.But the compaction material that down-hole is commonly used at present is that the cement of single label is as agglutinate, sand, stone etc. is coordinated to make, there is setting rate adjustment difficulty in such compaction material, Strength Changes scope is less, and compaction material only can meet the needs of part filling, and the scope of application is little.
Publication number is that the Chinese patent application of CN103570316A discloses a kind of filling expansion material, comprises volcano grey matter trade waste, basic material, gypsum, composite Portland cement, water and the admixture with latent hydraulicity; Each raw-material ratio is: the volcano grey matter trade waste mass percent 10 ~ 60% of latent hydraulicity; Basic material mass percent is not more than 40%; Gypsum quality per-cent is not more than 20%; Composite Portland cement mass percent is not more than 20%; Quality per-cent accounts for 30 ~ 60%; Admixture mass percent is not more than 4%; This filling expansion material, has good mobility, swelling property and ultimate compression strength, meets mine working filling and expansion connects top.
But its starting components is more, source is not extensive, obtains and has certain difficulty, and cause starting material to obtain difficulty, cost is higher; And this strength of materials is non-adjustable, and range of application is less, the down-hole application of above-mentioned this compaction material of many factors.
Therefore, need a kind of agglutinate that can adapt to the various filling requirement in down-hole of exploitation badly, avoid down-hole to be equipped with the situation of different compaction material according to different requirement of engineering.
Summary of the invention
In order to solve problems of the prior art, the object of this invention is to provide a kind of mining complex cement agglutinate and filler for mine material.
In order to realize the object of the invention, first the present invention provides a kind of mining complex cement agglutinate, and described agglutinate by weight, comprises following component: composite Portland cement 75 ~ 92 parts, aluminosulfate cement 5 ~ 15 parts and 3 ~ 10 parts, gypsum.
As preferably, described agglutinate by weight, comprises following component: composite Portland cement 82 ~ 92 parts, aluminosulfate cement 5 ~ 13 parts and 3 ~ 9 parts, gypsum.
Further, described composite Portland cement is the composite Portland cement of PC32.5 ~ PC42.5 level, and described aluminosulfate cement is 42.5 grades of quick hardening sulphoaluminate cements, and described gypsum is dehydrated gyp-.
