Abstract
The movable capping safe air-pocket of the working-face end in the integrated mining is characterized in that: a soft cyst is set for inflating or bleeding air. The inflatable shape of the soft cyst is pier. It erects on the base plates of the upper and lower ends of the integrated mining working-face. Its roof and both side parts are anastomotic with the roof board and the two side boards of the tunnel separately to form the capping wall of the integrated mining working-face ends. The invention takes place of the existing capping mode with coalsacks hacking and building wall, which can lighten the workers' working strength, save the resources and cost and improve the capping effect and reliability.
Description
Technical field:
The present invention relates to be applied in the fully-mechanized mining working faces end head plugging device in the Safety of Coal Mine Production process, more specifically saying so a kind of being particularly suited for should be in the faces end head plugging device on high gas layer and the projecting coal bed fully-mechanized mining working.
Background technology:
Along with the continuous intensification of the coal mining degree of depth, the high gas layer stope is more and more, and along with the improving constantly of coal mining technical level, the comprehensive mechanical coal mining work plane is more being popularized comprehensively.Fully mechanized coal winning technology is greatly improving output, benefit, safety, and when alleviating labor strength, also has some aspects to be badly in need of improving, and high gas fully-mechanized mining working faces end head plugging technology is exactly one of them.
At present, the two ends shutoff is that shutoff is carried out in the piling walling after adopting Polywoven Bag filling broken coal mostly about the fully-mechanized mining working.When work plane constantly advanced, the block wall of this form was immovable, so the shutoff work of two ends also will constantly repeat.Material is not only taken a lot of work, taken to this work in process of production, and labor strength is very big.Moreover, adopt Coal sack piling walling shutoff inleakage big, very easily cause upper and lower corner gas exceeding limit, bring very big hidden danger to safety in production.
Summary of the invention:
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of movable coal mine fully-mechanized mining working faces end head plugging air bag for safety is provided, the shutoff mode that substitutes the walling of existing Coal sack piling with the present invention improves the shutoff reliability when alleviating labor strength.
The technical scheme that technical solution problem of the present invention is adopted is:
Movable coal mine fully-mechanized mining working faces end head plugging air bag for safety of the present invention, its design feature is the soft capsule bag that the gas that can charge into or release is set, the inflated shapes of soft capsule bag is a pier, the soft air bag of pier shape of inflation stands on the upper and lower termination of fully-mechanized mining working base plate, and match with back and two side, tunnel respectively with its top and both sides, form the shutoff metope of fully-mechanized mining working faces end head.
Design feature of the present invention also is:
In a side of capsule bag, but the reduction connecting rod that connects with fully mechanized mining supporter in the tunnel is set, pull rope is set respectively on the diverse location of capsule bag.
Top and both sides at the capsule bag are provided with inflatable fold respectively.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention for changing the walling of Coal sack piling, has greatly alleviated working strength of workers in the mode of inflation.
2, the present invention adopts the form of air bag greatly to improve degree of agreement with back and both sides, and by pressurized with compressed air, it is good to make it have a good steadiness, and shutoff is reliable.
3, the transportable form of the present invention greatly subtracts and has fallen use cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Number in the figure: but 1 capsule bag, 2 tops, 3 sidepieces, 4 reduction connecting rods, 5 air inlet ports, 6 exhaust openings, 7 left side pull ropes, 8 overhead extension ropes, 9 right side pull ropes.
Below pass through the specific embodiment, and in conjunction with the accompanying drawings the present invention is further described.
The specific embodiment:
Referring to Fig. 1, setting can charge into or the release soft capsule bag 1 of gas, the inflated shapes of soft capsule bag 1 is a pier, the soft air bag 1 of pier shape of inflation stands on the upper and lower termination of fully-mechanized mining working base plate, and match with back and two side, tunnel respectively with its top 2 and both sides 3, form the shutoff metope of fully-mechanized mining working faces end head.
In concrete the enforcement, for the ease of location and mobile, the corresponding structure setting also can comprise:
Side at capsule bag 1, but the reduction connecting rod 4 that connects with fully mechanized mining supporter in the tunnel is set, pull rope is set respectively on the diverse location of capsule bag 1, comprises the right side pull rope 9 of left side pull rope 7, overhead extension rope 8, each pull rope also can be arranged on other different position as required.
In order to strengthen plugging effect, can inflatable fold be set respectively in the top and the both sides of capsule bag 1, the fold position can coincide better with back and sidewall after inflation.
In concrete the enforcement, in order to adapt to the colliery subsurface environment, capsule bag 1 is made by fire-retardant, antistatic, high-strength, soft, withstand voltage, encapsulant, and the different model air bag is withstand voltage to be set in 0.1～0.3 MPa.Use work plane to press wind to give the capsule bag 1 inflation, capsule bag 1 air inlet port 5 and exhaust opening 6 and relative set air valve and air gauge be set respectively up and down.
When coming into operation, but air bag is installed on the fully mechanized mining supporter by reduction connecting rod 4, last fixed point is positioned at air inlet port 5 positions, and following fixed point is positioned on exhaust opening 6 positions.Air bag is drawn the work plane position of establishing to required shutoff, utilize compressed air to arrive setting pressure to airbag aeration again, air bag gets final product the required shutoff drift section of complete closed, and enough support strengths are arranged, and reaches stifled wind effect.When the mobile fully mechanized mining supporter of needs, at first with the suitable exhaust of air bag, but utilize reduction connecting rod 4 and fully mechanized mining supporter to move to desired location jointly again, then replenish gas and carry out shutoff once more, form the one-stop operation circulation.
