Abstract
The utility model discloses a gas emission device of a coal mine. The gas emission device comprises a working face coal seam roadway, wherein the top of the working face coal seam roadway is provided with a plurality of gas emission wind tunnels. According to the gas emission device of the coal mine, because the top of the working face coal seam roadway is provided with the plurality of gas emission wind tunnels, the greatest superiority of zero distance emission is realized to ensure that gas is not accumulated on the working face; and the method of the gas emission device has the advantages of safety, simplicity, low cost, easiness of mounting and avoidance of gas explosion dangers and brings insurance to the life and property safety of people.
Description
Technical field
The utility model relates to the Safety of Coal Mine Production field, is specifically related to a kind of colliery exhaust plant.
Background technology
Mine gas gas is a kind of inflammable and explosive property gas; Its main component is a methane; This gas concentration runs into spark when reaching certain value can blast, thereby occur the colliery often the gas explosion phenomenon is arranged in recovery process, brings hidden danger for people's safety of life and property.In order to prevent gas explosion, to adopt for a long time simply to mine ventilation, dilution reduces the concentration of methane gas, and it is discharged outside the mine along the tunnel from pithead, but poor effect, can not be at short notice, with the methane gas emptying in the work plane heading.Particularly when gas bearing capacity is high in the coal seam, discharge by ventilating, technical have a great difficulty.Untimely when ventilating, when the gas density height arrives to a certain degree, be easy to occur the danger of gas explosion, cause casualties and property loss.
Summary of the invention
The technical problem that the utility model will solve provides a kind of colliery gas-removing wind-tunnel, makes gas not have savings at work plane, and the method is safe and simple; Expensive few; Be easy to install, avoided the danger of gas explosion, bring safety guarantee for people's safety of life and property.
The utility model is realized through following technical scheme:
A kind of colliery gas-removing wind-tunnel comprises the work plane heading, is provided with several gas-removing air ducts at said work plane heading top.
The further improved technical scheme of the utility model is: more than the said gas-removing air duct diameter 50cm.
The further improved technical scheme of the utility model is: elevate above the soil in the upper end of said gas-removing air duct, and the upper end of the gas-removing air duct after elevating above the soil is provided with air exhauster.
The utility model compared with prior art has following advantage:
The utility model is owing to be provided with several gas-removing wind-tunnel at work plane heading top; Accomplish the prime advantage of zero distance discharging, make gas not have savings at work plane, the method is safe and simple; Expensive few; Be easy to install, avoided the danger of gas explosion, bring safety guarantee for people's safety of life and property.
Description of drawings
Fig. 1 is the utility model schematic perspective view.
The specific embodiment
As shown in Figure 1, the utility model comprises work plane heading 1, is provided with several gas-removing air ducts 2 at said work plane heading 1 top; More than the said gas-removing air duct 2 diameter 50cm.Still as shown in Figure 1, elevate above the soil in the upper end of said gas-removing air duct 2; The upper end of the gas-removing air duct 2 after elevating above the soil is provided with air exhauster 3.
When the utility model uses, open and be arranged on gas air duct 2 top air exhausters 3, can discharge the methane gas of work plane at short notice.
Claims (4)
1. gas-removing device in colliery comprises work plane heading (1), it is characterized in that: be provided with several gas-removing air ducts (2) at said work plane heading (1) top.
2. a kind of colliery as claimed in claim 1 gas-removing device is characterized in that: more than said gas-removing air duct (2) the diameter 50cm.
3. according to claim 1 or claim 2 a kind of colliery gas-removing device, it is characterized in that: elevate above the soil in the upper end of said gas-removing air duct (2).
4. a kind of colliery as claimed in claim 3 gas-removing device is characterized in that: the upper end of the gas-removing air duct (2) after elevating above the soil is provided with air exhauster (3).
