Abstract
The invention relates to a hole sealing device for gas dust removal of spring barrels. The hole sealing device comprises a cylindrical cavity, a pressure-regulating spring and a blowdown discharge pipe. The pressure-regulating spring is coaxially docked with the cylindrical cavity, and the blowdown discharge pipe is connected to the side wall of the cylindrical cavity. The hole sealing device has the advantages that when a drill rod drills a coal bed, drilled holes are plugged by a gas dust collector, and after water or air pressure is added externally, and the gas dust collector radially expands to further keep drill rod operating space hermetical, so that slag and gas in the cold bed during operating of the drill rod are collected and water, gas and slag are sufficiently mixed to be discharged from pipelines under the condition of injecting a great quantity of dustproof water externally.
Description
Technical field
The invention belongs to the coal mining technical field, particularly the waste residues such as pressure wind row powder boring mud of ejection in the boring in the extraction borehole work progress dirt that goes out is handled, prevent from executing getting out the harm of transfiniting of existing dust, the site work environment of commentaries on classics is executed in optimization.
Background technology
Coal mine gas, dust accident are one of great disasters of down-hole, if gas, dust accident take place, not only can the heavy damage production environment, and can cause casualties, cause tremendous loss for the people, enterprise, country, therefore, eliminating gas exceeding limit and dust is the precondition of prevention gas, dust accident, also is one of important leverage of mine safety production.
Because geologic sedimentation effect, a large amount of toxic and harmfuls such as gas have been overstock in the coal seam, in order to realize safe digging, generally, at first to arrange special-purpose gas pumping tunnel before the digging, adopt underground drill rig construction extraction borehole to implement gas pumping in advance, treat that extraction is up to standard after, can begin digging coal.Yet in construction extraction borehole process, after particularly many mines enter deep horizontal, coal seam gas-bearing capacity, pressure all will increase, can be ejected into construction space because executing the gas dust that produces in the brill process and changeing refuse such as slag, the working environment of severe exacerbation construction, further, if dust exceeds standard in a large number and gas produces the danger of exploding, cause more serious loss.
But, in the prior art, not at the special-purpose drill hole gas of these serious problems go out dirt and dedusting and sealing of hole integrated apparatus, execute therefore that a large amount of gas dust, boring mud can be released in the tunnel in the brill process, cause potential safety hazards such as serious gas exceeding limit and dust exceed standard.
Summary of the invention
The objective of the invention is to be discharged into and to construct in the tunnel as space security hidden trouble, a kind of hole sealing device of proposition such as cause that dust transfinites in order to solve in the tunnel in the construction extraction borehole process in the boring gas dust boring mud of ejection.
Technical scheme of the present invention is: a kind of hole sealing device, it is characterized in that, and comprise straight-tube shape cavity, pressure spring and blowdown slag pipe; Described pressure spring docks with the straight-tube shape cavity is coaxial, and blowdown slag pipe is connected in the sidewall of straight-tube shape cavity;
Described straight-tube shape cavity is that the static fire retardant of tubbiness realizes that both ends of the surface comprise support by stitching, and described support comprises the drilling rod hole that is positioned at the end face center and the spoke of jointed rod hole and straight-tube shape cavity end face, and described spoke is used for support bull stick hole;
Further, described a kind of hole sealing device also comprises nozzle, and described nozzle is fixed on the sidewall of straight-tube shape cavity, and described nozzle is connected with water pipe implements the dirt that goes out of spraying water to the dust that is created in the chamber;
Described nozzle further is connected with pressure air pipe, makes nozzle ejection water and the mixture of pressing wind;
Described blowdown slag pipe is connected in tubular chamber sidewall, is used for being pressed wind and nozzle water spray to produce go out gas dust behind the dirt and the mixture ejectment of water of stream and goes out.
The invention has the beneficial effects as follows: when being drilled into the coal seam owing to drilling rod, boring is blocked by gas dust packing device, after particularly will adding outside water or air pressure, the expanded radially of gas dust packing device has further kept the seal of drilling rod working space, so the waste residue that produces in the drilling rod course of work, the methane gas in the coal seam are all by packing and externally inject and form the abundant mixture of aqueous vapor slag under the situation of a large amount of dustproof water and discharge by pipeline.
