Abstract
A mining device for removing orifice dust and gas accumulation includes an orifice dust collector, a primary dust removing tube, a spray dust removing tube and a secondary spray dust removing tube. Awater-pressurized dust removal tube is arranged at the end of the orifice dust collector. The primary dust removing tube, the spray dust removing tube and the secondary spray dust removing tube are sequentially connected through air ducts. Nozzles are respectively equipped on the upper end of the spray dust removing tube and the secondary spray dust removing tube. A snakeskin bag is fixed on the bottom of the primary dust removing tube. The utility model effectively removes mixed gas of coal in pore, rock dust and gas in an entire closed system, solves the problem of rock dust flying in laneway and transfinite gas in laneway, integrates the dust removal and gas suction and drainage, and has low cost and no potential safety hazard.
Description
Technical field
The utility model relates to the coal mine operation dust arrester, and the dedusting of mining aperture, the gas accumulated slag device in the wind deslagging drilling construction process pressed in specifically a kind of colliery that is applicable to.
Background technology
The general wet boring that adopts solves dust problem in the firedamp taking-out discharging drilling construction under the existing coal mine, but no matter be wet boring or dry drilling, the coal petrography powder that produces when boring is along drilling rod and the hole wall gap blows out and even make the pollution condition of dust increase the weight of, tunnel working space and work plane have greatly been polluted, had a strong impact on the healthy of operating personnel, caused the rising of local dust concentration simultaneously and bring potential safety hazard.Though some traditional dust arresters have functions such as basic dedusting, slagging-off, all be after coal, rock dirt fly upward in the tunnel, to carry out dedusting work again, therefore just carry out simple dedusting, and can not carry out in real time, cause dust removing effects very poor; In addition, dust arrester all has electric appliance component usually, exists the possibility that produces static and spark, exists potential safety hazard under high gas environment.
The utility model content
At above defective, the purpose of this utility model provide a kind of cheap, dust removal efficiency is higher, overcome the dedusting of mining aperture, the gas accumulated slag device of potential safety hazard, thereby can realize that efficiently Bian Caibian takes out integrated and can solve that rock dirt flies upward, the problem of tunnel gas exceeding limit in the tunnel.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of mining aperture dedusting, gas accumulated slag device, comprise aperture dust arrester, elementary dust removing tube, spray for dust suppression pipe and secondary spray for dust suppression pipe, the end of described aperture dust arrester is provided with setting-out depositing dust pipe, and the aperture dust arrester end that is positioned at setting-out depositing dust pipe bottom is provided with the rubber sleeve gasket; The lower port of described aperture dust arrester is connected to the inside of elementary dust removing tube by air inlet pipe, and the bottom of described elementary dust removing tube is the snakeskin bag fixedly; Described elementary dust removing tube, spray for dust suppression pipe, secondary spray for dust suppression pipe are connected in series by wireway successively; The upper end of spray for dust suppression pipe and secondary spray for dust suppression pipe is respectively equipped with nozzle.
The beneficial effects of the utility model are: simple in structure, cheap, realized that coal in the hole, rock dirt and gas mist removed by high efficiency in whole closed system, solved that coal, rock dirt fly upward in the tunnel, the difficult problem of tunnel gas exceeding limit, dust removing effects can reach more than 90%; Utilize the principle of aperture dust arrester and sealing dedusting, in whole closed system, get final product dedusting, and realized that dedusting, gas Bian Caibian take out integrated; This device is not provided with electric appliance component, can not produce static and spark, does not exist to produce potential safety hazards such as static or spark under the high gas environment; Saved the energy, applied widely, have good expansibility.
