Abstract
The invention relates to flexible airbags for a coal working face and a method adopting the same to block off corners. Each flexible airbag comprises an airbag body and a fixed ring arranged on the periphery of the airbag body; wherein the airbag body comprises an inner container and an outer container; and air inlet valves and pressure releasing valves are arranged on both the inner container and the outer container. The method comprises the following steps: firstly, single props are arranged at upper and lower corners of the coal working face at intervals, and are fixed between a top plate and a bottom plates of a roadway; the single props are positioned in the same plane parallel to the coal working face; one flexible airbag for the coal face is arranged on the side, far from the coal working face, of each single prop; the flexible airbags are fixed on the single props to inflate the single props; and the upper corners and the lower corners of the flexible airbags for the coal working face, filled with air, are filled by the flexible airbags. The flexible airbags are simple in structure, convenient to use, and good in block-off effect. The method realizes the mechanized blocking off, and not only is high in efficiency and good in block off effect, but also reduces the labor intensity of workers greatly.
Description
Technical field
The present invention relates to a kind of safety of coal mines device, be specifically related to a kind of flexible air-bag and adopt the method for blocking of this flexible air-bag.
Background technology
In the coal mining process, at the corner place, in order to isolate as much as possible the fresh distinguished and admirable goaf that enters, avoid the spontaneous combustion of remaining coal in goaf, simultaneously also for fear of the distinguished and admirable gas density of taking the gas in goaf out of and then affecting work plane, the glue that generally adopts accumulation to fill broken coal on the ore deposit is at present knitted bag and is cooperated individual prop to come the shutoff corner, this method inefficiency, also cause to a certain extent the waste of resource, and greatly increased workman's labour intensity, affected the economic benefit in colliery.
Summary of the invention
Primary and foremost purpose of the present invention provides a kind of coal-face flexible air-bag, and it is simple in structure, easy to use, plugging effect is good, and reduces workman's labour intensity.
Another object of the present invention provides a kind of method that adopts this air bag shutoff corner, and the method has realized the mechanization shutoff, and not only efficient is high, plugging effect is good, and greatly reduces workman's labour intensity.
To achieve these goals, technical solution of the present invention is: a kind of coal-face flexible air-bag, comprise utricule and be arranged at several retainer rings of utricule periphery, utricule comprises separate inner bag and outer courage, is equipped with admission valve, relief valve on inner bag and the outer courage.
Coal-face flexible air-bag of the present invention, wherein, described inner bag is made by the high-strength PVC coating cloth of plastic ventilator, and outer courage is made by rubber coated cloth.
The present invention adopts the above-mentioned coal-face method of flexible air-bag shutoff corner, may further comprise the steps, at first at the interval, up and down corner place of work plane several individual props are set, each individual prop is fixed between roadway floor and the top board, several individual props are positioned at the same plane that is parallel to work plane, then be close to individual prop in the side away from work plane of individual prop several coal-face flexible air-bags are set, coal-face is fixed on the monomer column with flexible air-bag, coal-face is inflated with flexible air-bag, and several coal-faces that are full of gas are full of up and down corner space with flexible air-bag.
The method of shutoff corner of the present invention, wherein, described individual prop comprises oil cylinder, live cylinder and hydraulic system, makes cylinder alive stretch out oil cylinder and is resisted against on the back by hydraulic system.
The method of shutoff corner of the present invention wherein, is passed described coal-face with steel wire and is fixed on the monomer column with the retainer ring on the flexible air-bag.
After adopting such scheme, coal-face of the present invention with flexible air-bag owing to being equipped with admission valve, relief valve on inner bag and the outer courage, but therefore inflation/deflation is simple in structure, easy to use, and plugging effect is good after the inflation, reduction workman's labour intensity.
Coal-face of the present invention flexible air-bag is fixed on the individual prop owing to first individual prop being set, so shutoff efficient is high, effective with the method for flexible air-bag shutoff corner again, and realizes the mechanization shutoff reducing workman's labour intensity.
