Description
Technical field
The utility model belongs to mine down-hole construction gas extraction hole blowout prevention technology field.
Background technology
For coal and gas outburst mine, for implementing regional gas control work, it is a kind of Main Means that coal mine gas is administered that punching draws out methane.The fundamental way of projecting coal bed improvement gas is to draw out methane, and wants to obtain good extracting result, first needs advanced technique of drilling and ensures.In order to prevent from drilling, period transfinite boring of gushing out of gas dust causes the accident, and during construction extraction boring, need to install blowout hookup additional, the effect of blowout hookup directly affects the personal safety of the speed of drilling and drilling construction personnel.Current blowout hookup of drilling is arranged on the position of drill orifice, and it is primarily of formations such as collecting cover, connecting hose, air water slag separator box, drawing-off gas mouth, slag-drip openings.During normal work, the coal and non-coal gushed out is entered in air water slag separator box along connecting hose by collecting cover, and isolated gas is taken away by drawing-off gas mouth, and cinder and moisture content are discharged by slag-drip opening.When practice of construction is holed, due to some rough and uneven in surface or inclinations of rib, cause between collecting cover and rib and still there is certain interval, if when the coal and non-coal amount gushed out is more or pressure is larger, coal and non-coal will be caused along the gap ejection between collecting cover and rib, coal dust flies away spacial influence drilling construction on the one hand, causes gas density to raise on the other hand, impacts safety in production.
Summary of the invention
The purpose of this utility model is to provide a kind of simple to operate, easy to use, mine underground device for preventing blowout of drill holes that blowout prevention dust-laying effect is good.
To achieve these goals, the utility model comprises: support, rig, drilling rod, drilling rod orienting cover, collecting cover, aperture sealing of hole cover, air water pulp separator, connecting hose, arrangement for adjusting height, front-and-back adjusting device, rig is fixed on support upper rear end, drilling rod orienting cover is arranged on support upper front end, drilling rod is arranged in rig and drilling rod orienting cover, drilling rod orienting cover front end is provided with collecting cover, arrangement for adjusting height and front-and-back adjusting device is respectively arranged with in the bottom of drilling rod orienting cover, corrugated horn shape aperture sealing of hole cover is connected with in the front end of collecting cover, the bottom of collecting cover is connected with air water pulp separator by connecting hose.
Like this when drilling, first drilling rod is installed in rig and drilling rod orienting cover, operation arrangement for adjusting height and front-and-back adjusting device, corrugated horn shape aperture sealing of hole cover is made closely to cover boring sites in curing, air water pulp separator is connected to collecting cover by connecting hose, feed water inlet on air water pulp separator is connected to the supply channel of down-hole, drawing-off gas mouth on air water pulp separator is connected to the gas drainage pipeline of down-hole, start rig and carry out drilling construction, the air water slag gushed out in rib boring is by aperture sealing of hole cover, collecting cover, flexible pipe enters air water pulp separator, after depositing dust, the slag-drip opening of grain slag in air water pulp separator bottom flows out, gas is taken away by the drawing-off gas mouth on air water pulp separator top.Owing to being connected with corrugated horn shape aperture sealing of hole cover at the left end of collecting cover and operating front-and-back adjusting device, sealing of hole cover or inclination rib rough and uneven in surface with some in aperture can be made to contact tight reliable, corrugated horn shape aperture sealing of hole cover has certain expansion space performance in addition, thus effectively alleviate nozzle pressure, coal and non-coal can not be there is and spray the leakage problem caused in a large number from aperture, effectively solve pollution caused by coal dust environment and the gas exceeding limit problem of drilling.There is the features such as simple to operate, easy to use, blowout prevention dust-laying effect is good, guarantee job safety of drilling.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
