Description
Technical field
The present invention relates to dust removing down-hole of coal mine additive, particularly relate to a kind of wet type water-retentivity dustfall agent.
Background technology
Along with the raising of mechanization production level in mining production process, the dust-producing amount of down-hole mining working face also increases thereupon fast.Survey factually, under the condition not taking any dust prevention, the dust concentration of fully mechanized workface can reach 2000mg/m
3-3000mg/m
3, the dust concentration of fully-mechanized mining working can reach 2500mg/m
3-3000mg/m
3, and fully mechanized coal face owing to moving frame, putting the operations such as coal all can volume production dirt greatly, the instantaneous original total dust concentration in some colliery is even up to 8000mg/m
3-10000mg/m
3.High concentrate dust the serious threat safety in production of mine and the healthy of worker.
In order to reduce the high concentrate dust of getting working face severe overweight, at present, the dedusting method extensively adopted both at home and abroad mainly contains dust removal by ventilation, coal-bed flooding, atomizing de-dusting, chemical dust suppression etc.Among numerous dust control technology means, wet spray depositing dust mode is most widely used, but simple water spray can only control the disperse of dust to a certain extent, and dust removing effects is poor.Also occurred more dustfall agent in prior art, but its wettability is poor, evaporation is very fast, easily makes dust again kick up, and forms secondary pollution.
Therefore, prior art needs further improvement and develops.
Summary of the invention
The present invention provides a kind of wet type water-retentivity dustfall agent for the defect in solving the problems of the technologies described above, and after parcel dust, can keep moistening for a long time, to extend the action time of dustfall agent.
For solving the problems of the technologies described above, the present invention program comprises:
A kind of wet type water-retentivity dustfall agent, wherein, it comprises following component according to weight percent:
It effectively can reduce the surface tension of water, enables water spray better wrap up dust, has high wetting water-retentivity, can effectively reduce getting working face dust concentration, suppress for a long time to working face dust.And starch grafted acrylate and cetyl trimethylammonium bromide are water-holding agent, in starch grafted acrylate, starch and acrylate are prepared according to the ratio of 1:4 ~ 1:7, starch grafted acrylate is condensed by high-efficiency water-absorbing performance, and has long-term water-retentivity.Cetyl trimethylammonium bromide water soluble, produces a large amount of foam during concussion, can have good coordinating with positively charged ion, nonionic, amphoterics.The liquid that interpolation water-holding agent is finally formed has high stability, high-moisture-retention.
Described wet type water-retentivity dustfall agent, wherein, it comprises following component according to weight percent:
