Abstract
The utility model is the technological improvement of the gas pumping in the mine; the name is a kind of mine gas pumping device, which is composed of the tubular gas pumping pipe (1). The characteristics are: the gas pumping pipe (1) is inserted above the coal seam (3) across the land surface (2), and also can be inserted in the coal seam (3); on the tube wall of the gas pumping pipe (1) is one or more than one hole (4); the gas pumping pipe (1) can also be composed of one or more than one pipeline; in use, when one is broken, others can still be used to effectively avoid the deficiency that the gas pumping pipe is broken and blocked and can not pump gas; the pipeline can pump part of the gas in the mine seam to reduce the gas quantity in the mine seam and decrease the rate of security accidents; the prior easing and pumping ensures the safety in opening the roadway and mining. The model is reasonable in structure; the gas pumping effect is good and the model can be safely and reliably operated.
Description
Technical field
The utility model 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, and 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, and the queueing problem that solves gas is the matter of utmost importance of mine safety.Improvement to the gas pumping device has become the problem that people can't avoid.
Summary of the invention
The purpose of the utility model design provides a kind of device that can overcome the colliery gas pumping of above-mentioned defective, be characterized in being to exploit before the colliery and in the process of mining, just by the surface layer above coal seam and 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 pipe more than one and, in use, exhaust tube can not break simultaneously, if wherein one break, then other still can use, avoid the pump-line blocked defective that can't extract gas out of breaking effectively, reduced cost in fact, it is simple and reasonable, gas pumping is effective, makes it to move safely and reliably.Its technical scheme is:
To achieve these goals, the utility model 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 utility model 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 one and an above exhaust tube.
To achieve these goals, the utility model 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 utility model 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 utility model 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 utility model also 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 utility model also 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.
