Description
Technical field
The utility model patent relates to coal mine work area exploitation, especially top-coal caving face exploitation.
Background technology
Mine Dust is healthy to workman, ecological environment has very large harm around coal mine production safety and colliery.Data show, 1 ~ October in 2010, dead 2080 people of national mine safety accidents, but annual Death from Pneumoconiosis number is more than 6000, is 2 times of work safety accident death toll.Colliery about 265, the whole nation connects dirt personnel, pneumoconiosis prevalence rate 7.72%, the death rate 3.24%.In top-coal caving face exploitation, push up coal to transfer and hydraulic moving stand is two of fully mechanized coal face and mainly produces dirt source, account for that comprehensive coal face dust produces about 60%.Due to work plane narrow space, flow field of airflow is complicated, and after support, tail boom spraying cannot meet the effect of dedusting far away, and therefore, the effective ways that research reduces top-coal caving face dust have important economic society meaning.Foam dust-removing, as one of the mode of coal mine dedusting, has significant superiority, particularly in comprehensive extracting and caving face, adopts foam dust-removing effectively can not only reduce dust concentration, and can save very big water resource.
The Dust Control Technology that current home and abroad colliery extensively adopts mainly contains coal-bed flooding, atomizing de-dusting, utilizes deduster dedusting, dust removal by ventilation etc.The research of foam dust-removing mode is in west the 1950's the earliest, and large-scale application is in the former Soviet Union.China begins one's study in the eighties in last century the application of foam dust-removing, and start gradually in some collieries to substitute the dedusting methods such as original coal-bed flooding with foam dust-removing, its efficiency is compared and is greatly improved.Table 1 is Sub-Level Caving dedusting method contrast chart.
The existing several dedusting method of table 1 compares
Contrast above-mentioned dedusting method, foam dust-removing not only have coal-bed flooding, atomizing de-dusting, deduster dedusting, dust removal by ventilation effect and also have following characteristics: on caving coal seam, spray one deck foam, can from the diffusion that initially just can prevent dirt source better; Time in the process of top coal caving, bubble jet is spread across the contact probability dirt source of having spread adding foam and powder dust particle; The liquid film of foam contains special blowing agent, significantly can reduce the surface tension of water, the adsorbed on interfaces that foaming jizi for making dumplings contacts with dust granules at the aqueous solution, changes rapidly the wet performance of dust, increases dust by moistening speed.
