Technical field
The present invention is the technological improvement to mine gas pumping device, and it is called the device of a kind of colliery gas pumping.
Background technology
In the prior art, it all is to adopt to drive a well earlier to beat the tunnel that the gas in colliery is got rid of, gas is discharged in the back, but it is outstanding that gas explosion and gas just might take place when opening tunnel or coal mining, the queueing problem that solves gas is the matter of utmost importance of mine safety, and the improvement of gas pumping device has been become the problem that people can't avoid.
Summary of the invention
The purpose of the present invention design provides and a kind ofly can overcome above-mentioned defective, its main feature is before the exploitation colliery and in the process of mining, just the device of the colliery gas pumping that the present invention is designed is by on the surface layer above coal seam and the coal seam, take the gas in the coal seam away a part, reduced the content of the gas in the coal seam, can reduce the probability that security incident takes place, exhaust tube can be made up of the plastic pipe more than one and, in use, if wherein one breaks, then other still can use, avoid the pump-line blocked defective that can't extract gas out of breaking effectively, dredge in advance and draw out methane the safety when having guaranteed to play tunnel and mining, the danger when having reduced production.It is simple and reasonable, and gas pumping is effective, makes it to move safely and reliably.
To achieve these goals, the present invention can adopt following measure to realize, the device of described colliery gas pumping, form by exhaust tube in a tubular form, it is characterized in that exhaust tube passes the top that surface layer inserts the coal seam, also can insert in the coal seam, one and more than one hole are arranged on the tube wall of the lower end of exhaust tube.
To achieve these goals, the present invention also can adopt following measure to realize, the device of described colliery gas pumping is characterized in that the end of bleeding of aspiration pump links to each other with exhaust tube more than one and one.
To achieve these goals, the present invention also can adopt following measure to realize, the device of described colliery gas pumping is characterized in that peripheral equipment one sleeve pipe of described exhaust tube.
To achieve these goals, the present invention also can adopt following measure to realize, the device of described colliery gas pumping is characterized in that on the tube wall of lower end of described sleeve pipe and exhaust tube one and more than one hole being arranged respectively.
To achieve these goals, the present invention also can adopt following measure to realize, the device of described colliery gas pumping, it is characterized in that described exhaust tube can be made up of the pipe more than one and, the upper end of exhaust tube with connect together communicating pipe with aspiration pump bleed the end link to each other after, in the parallel insertion sleeve pipe of exhaust tube.
To achieve these goals, the present invention can adopt following measure to realize, the device of described colliery gas pumping is characterized in that the lower end of described exhaust tube can be shorter than the lower end of sleeve pipe, also can be concordant with the lower end of sleeve pipe, also can be longer than the lower end of sleeve pipe.
To achieve these goals, the present invention can adopt following measure to realize, the device of described colliery gas pumping is characterized in that described sleeve pipe is one deck and the above sleeve pipe of one deck.
To achieve these goals, the present invention can adopt following measure to realize, the device of described colliery gas pumping, the plastic pipe that can be that it is characterized in that described sleeve pipe, also can be steel pipe, also can be outer for the steel pipe internal layer is a plastic pipe, also can be outer for the plastic pipe internal layer is a steel pipe, the lower end of exhaust tube and sleeve pipe has one and more than one hole respectively.
To achieve these goals, the present invention can adopt following measure to realize, the device of described colliery gas pumping is characterized in that described exhaust tube and sleeve pipe can be respectively a kind of in other tubes of material such as steel pipe, plastic pipe, steel-plastics composite pipe, steel wire wind pipe, glass reinforced plastic pipe.
