Description
Technical field
The utility model relates to a kind of inflation appliance, is used in particular for the secretion between coal-face end support and portion of side, tunnel, reduces goaf gas and gushes out, and is convenient to the coal-face corner methane monitor inflation bag carrying out corner gas pumping.
Background technology
Coal-face corner gas administration is the emphasis of mine gas management, method conventional when carrying out corner gas control has intubate to take out in advance to take out in advance with pipe laying, but two kinds of modes of taking out in advance all need to set Coal sack wall in advance and reserve the space that roughing pipe buries underground on Coal sack wall top, owing to needing in advance of the face process often to pass support, and Coal sack wall is piled up and is taken a lot of work, time-consuming, therefore coal-face face end support is passed between after-poppet and Coal sack wall and can be produced larger space for a long time, old dead zone gas is gushed out along space, reduce corner gas pumping efficiency, and bring difficulty to face gas improvement.
Adopt inflation bag to carry out filling, can greatly reduce worker's labour intensity, improve coal recovery rate, reduce the influence time to coal-face; But, utilize inflation bag to carry out in the technical scheme of filling, the not circulated gases still existed between coal-face corner and each side of inclusion, do not solve the problem that coal work plane corner easily accumulates methane gas completely, there is hidden danger.
Utility model content
The utility model, according to the difficult problem existed in coal-face corner gas administration, provides a kind of coal-face corner methane monitor to inflate bag, effectively can solve a difficult problem for coal-face corner gas pumping.
The technical scheme taked for achieving the above object: coal-face corner methane monitor inflation bag of the present utility model, comprise inclusion and connector, in inclusion side, inflation inlet is installed, inclusion is also provided with gas outlet, gas outlet is provided with flow control valve, in the entrance location of flow control valve, relief valve is installed.Described gas outlet is arranged on inclusion side, or is arranged on all sides of inclusion.Side is provided with a gas outlet, or simultaneously uniformly on side is provided with multiple gas outlet.Described connector is the retainer ring being arranged on inclusion edge.Relief valve is provided with the valve controlling pressure release amount size.Described inclusion is tetragonal body shape.Described inclusion, inflation inlet, gas outlet and retainer ring all adopt anti-electrostatic fire retardant cloth to process.
Technique effect of the present utility model is: 1, in inflation bag, be filled with pressure wind by inflation inlet, inclusion is expanded.Important feature of the present utility model is, the gas outlet of setting can continuous Exhaust Gas, and under Flow-rate adjustment valve action, intake velocity is greater than the speed of giving vent to anger, thus inclusion expands.Exhaust endlessly can make the not circulated gases still existed between coal-face corner and inclusion circulate, thus makes inclusion surrounding there is not dead angle.Relief valve can guarantee that in inclusion, gas more than needed is discharged, prevent inclusion from overcharging, to reach filling coal mining working face ended support, between goaf extraction pipeline and portion of side, tunnel space, reduces goaf gas and outwards gushes out, reduce worker's labour intensity, improve the object of goaf extraction efficiency.Can the difficult problem of fully effective solution coal-face corner gas pumping.
2, inflating bag is convenient to mobile, easily fixes, swift to operate, does not need other supporting facilities, can Reusability, can greatly reduce worker's labour intensity, improve coal recovery rate, reduce the influence time to coal-face.
3, inflation bag is changeable, makes simple and easy, economical and practical, face end support, space between goaf extraction pipeline and portion of side, tunnel can be full of, and reduces goaf gas and outwards gushes out, improve goaf extraction efficiency.

Detailed description of the invention
Embodiment 1: as shown in Figure 1, the first coal-face corner methane monitor inflation bag, the edge of its inclusion 1 is respectively arranged with retainer ring 6, is fixed on the optional position of coal-face corner by fixture as required, without the need to other supporting equipment, so need not consider the supporting tools such as the column on ground, thus inflation bag is convenient to mobile, swift to operate, can Reusability, greatly reduce worker's labour intensity, improve coal recovery rate, reduce the influence time to coal-face.
Described inclusion 1 adopts the tetragonal body shape with coal-face corner form fit usually.
In Fig. 1, not only in inclusion 1 side, inflation inlet 2 is installed, and on inclusion 1, gas outlet 3 is also installed.Meanwhile, gas outlet 3 is provided with flow control valve 5, in the entrance location of flow control valve 5, relief valve 4 is installed.The valve controlling pressure release amount size can also be provided with on relief valve 4.Inclusion 1, inflation inlet 2, gas outlet 3 and retainer ring 6 all adopt anti-electrostatic fire retardant cloth to process.
Coal-face corner methane monitor inflation bag, its using method: a, the inflation bag selecting slightly larger than the space between coal-face corner place's support and portion of side, tunnel, place and also fix appropriate in portion of side, tunnel; B, by the hanging of goaf extraction pipeline at the top in this space, place; C, pressure ventilation pipe inserted inflation inlet and by inflation inlet and pressure ventilation pipe fixed, prevent from coming off or leaking gas; D, in inclusion, be filled with pressure wind, inclusion heaved and is full of space between goaf extraction pipeline and portion of side, tunnel, and outwards exhaust forms circulating current, make extraction pipeline in goaf keep extraction state; Of short duration stopping to air feed in inclusion and simultaneously moving charging gas bag when e, coal-face pass support, support is passed and is terminated rear repetition above-mentioned steps and recover to air feed in inclusion.
Embodiment 2: see Fig. 2, the second coal-face corner methane monitor inflation bag, main contents are identical with embodiment 1, unlike: gas outlet 3 is arranged on all each sides of inclusion 1.Thus no matter how inclusion 1 is fixed, the gas circulation of its each side can be ensured.
Embodiment 3: see Fig. 3, the third coal-face corner methane monitor inflation bag, main contents are identical with embodiment 1, unlike: uniformly on side while be provided with multiple gas outlet 3.Thus, gas is sprayed for source of the gas center respectively to its periphery six faces with inclusion 1, increase the gas flow general character more fully, especially make the gap gas between inclusion 1 and coal-face corner circulate, or the gap gas between multiple adjacent inclusion 1 is circulated.
