Description
Technical field
The present invention relates to a kind of disconnected pipe device more particularly to a kind of disconnected pipe structures for coal mine gob pipe laying, belong to
Coal mine gas drainage equipment technical field.
Background technique
Pipe laying extraction is the most effective side that a kind of common processing Top Corner Gas on Coal Face in mining area of southwest China transfinites
Method, preventing coal work face goaf Neva, this gushes out to upper corner.But if in goaf because adopt face there are top (bottom)
There is spontaneous combustion in coal, and pipe laying extraction must can aggravate gas in goaf and flow, and has encouraged the speed of goaf spontaneous combustion of coal seam, thus
The generation for leading to goaf fire incident brings safety accident, gently then close the goaf and adopts face, heavy then close entire mine.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of disconnected pipe structure for coal mine gob pipe laying, make to mine
Working face pipe laying extraction position is distributed in the heat dissipation region of three band of heterogeneous goaf, can effectively avoid gas in oxidized zone
Flowing, prevents coal body spontaneous combustion in oxidized zone, can play goaf gas in this way and not gush out to coal working face and effectively control
Coal body spontaneous combustion speed in goaf oxidized zone processed, so that preventing goaf coal body spontaneous combustion occurs fire incident, effective solution
Above-mentioned problem.
The technical solution of the present invention is as follows: a kind of disconnected pipe structure for coal mine gob pipe laying, it includes columnar iron
Pipe is connected with flange at the both ends of iron pipe, and iron pipe is connect by flange with pipe laying, and the centre of the iron pipe passes through rectangular drawer
Box is fixedly connected, and tripartite's sealing of the drawer box, side, which is equipped with, to be open and be fixedly connected with square flange, and having in method flange aperture can
Square flange lid has been bolted in the closure plate of extraction, square flange outside.
The drawer box is two pieces of square plate structures being arranged symmetrically, and the spacing between two pieces of plates is greater than the thickness of closure plate
It spends, three sides between two pieces of plates are welded seal structure, are provided with circular hole in the centre of plate, iron pipe is inserted into circular hole simultaneously
It is connect with plate welding.
The closure plate is rectangular slab construction.
The beneficial effects of the present invention are: compared with prior art, using technical solution of the present invention, by using goaf
Pipe laying breaks pipe device, and pipe laying extraction position relatively fixed can be distributed in the heat-radiation belt of goaf, and oxidized zone is reduced or avoided
Interior gas flowing, greatly reduces and pushes up (bottom) float coal autoxidation speed in oxidized zone, eventually enter into suffocative zone.According to mined out
Area's spontaneous combustion three can be effectively controlled the gas flowing of goaf oxidized zone, can greatly reduce the hair of goaf fire incident with division
It is raw, achieve good using effect.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is side view of the present invention；
Fig. 3 is top view of the present invention；
Fig. 4 is schematic view of the mounting position of the invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below with reference to this specification attached drawing to this hair
It is bright to be described in further detail.
Embodiment 1: as shown in attached drawing 1~4, a kind of disconnected pipe structure for coal mine gob pipe laying, it includes cylindrical shape
Iron pipe 1, be connected with flange 4 at the both ends of iron pipe 1, iron pipe 1 is connect by flange 4 with pipe laying, and the centre of the iron pipe 1 passes through
Rectangular drawer box 2 is fixedly connected, and tripartite's sealing of the drawer box 2, side, which is equipped with, is open and is fixedly connected with square flange 5,
There is the closure plate 3 that can be extracted out in 5 hole of square flange, square flange lid 6 has been bolted on the outside of square flange 5.
Further, drawer box 2 is two pieces of square plate structures being arranged symmetrically, and the spacing between two pieces of plates is greater than stifled
The thickness of plate 3, three sides between two pieces of plates are welded seal structure, are provided with circular hole in the centre of plate, iron pipe 1 is inserted into
It is connect in circular hole and with plate welding.
Further, closure plate 3 is rectangular slab construction.
Further, drawer box 2 welds together with iron pipe 1, after needing that closure plate 3 is injected 2 the inside of drawer box when disconnected pipe,
The sealing of square flange lid 6 is fixed on drawer box 2 using bolt, breaks off the extraction amount in goaf, to change the extraction of pipe laying
Position.
Further, drawer box 2 is processed using the iron plate of two pieces of at least 5mm thickness, and there are the gaps of 10mm between iron plate, so
It is welded on iron pipe 1 afterwards from the bottom of one's heart according to iron pipe size afterwards.There are the gaps 10mm in drawer box 2, wherein three sides are sealed using electric welding,
In addition on one side convenient for injecting closure plate 3, the side of drawer box 2 is welded with square flange 5.
Further, closure plate 3 is processed using 5mm thickness iron plate, and surrounding is rounded down, and prevents closure plate from inserting not into drawer box 2
It is interior.
Further, pipe laying disconnected pipe device in goaf is necessarily mounted in front of pipe laying extraction threeway (by goaf direction),
Pipe laying extraction threeway spacing can be determined according to coal mine itself coal seam heat dissipation strip length, after bypass pipe extraction effect, can be used stifled
Section in pipe laying is broken off extraction by plate.
Further, there is rubber mat Zuo Wei Cun pad on one side by extraction threeway in drawer box, sealing can be played after insertion closure plate 3 and made
With.
By using the disconnected pipe device of goaf pipe laying, pipe laying extraction position relatively fixed can be distributed in goaf heat dissipation
In band, gas in oxidized zone is reduced or avoided and flows, greatly reduces and pushes up (bottom) float coal autoxidation speed in oxidized zone, finally
Into in suffocative zone.According to heterogeneous goaf three with division, it can be effectively controlled the gas flowing of goaf oxidized zone, can subtract significantly
The generation of few goaf fire incident, achieves good using effect.
Place is not described in detail by the present invention, is the well-known technique of those skilled in the art of the present technique.Finally, it is stated that the above reality
It applies example to be only used to illustrate the technical scheme of the present invention and not to limit it, although having carried out specifically the present invention referring to preferred embodiment
It is bright, those skilled in the art should understand that, can with modification or equivalent replacement of the technical solution of the present invention are made, and
The objective and range for not departing from technical solution of the present invention, are intended to be within the scope of the claims of the invention.
