Description
Technical field
The present invention relates to a kind of orifice dust catcher.
Background technology
At present in the colliery of pit mining, when implementing technical safety measures, need to get out firedamp taking-out discharging drilling, coal-bed flooding boring, fire extinguishing inlet well etc., and the Slagoff method of these borings of constructing mainly contains water deslagging and wind deslagging two kinds.Water deslagging mobility is better, be easy to discharge cinder in boring, and effectively can reduce the generation of dust, but it is large to there is water consumption in its technique, moistening coal body easily forms collapse hole, pore-forming poor-performing, easily causes the shortcomings such as tunnel ponding, especially, when the drainage system that mine is imperfect, water deslagging technique cannot be constructed.Wind deslagging pore-forming is good, also can construct in the place of some difficulties that supply water, this technique applicability is comparatively strong, applies wider, but can bring comparatively serious dust pollution question in its work progress, the dust concentration that this operating type produces can up to 1000mg/m at local space
3above, high concentrate dust with distinguished and admirable diffusion, serious harm development end and work plane operating personnel healthy, and likely cause dust local accumulation, there is the risk of dust explosion, the production safety of mine in serious threat.
For generally adopting the coal mining enterprise of wind deslagging-drilling construction technology, effective solution dust pollution question is one cannot be avoided, and the technical problem that must solve.At present, conventional measure comprises aperture spraying, the spraying of return tunneling boring, deduster depositing dust etc., but these measure dust-laying effects are unsatisfactory, usually only have the dustfall efficiency of about 30% ~ 40%, still have up to nearly 600mg/m near aperture
3above dust concentration, considerably beyond state health standards requirement.
In sum, a kind of method and apparatus that effectively can solve boring dust pollution is not also had in prior art.
Summary of the invention
