Description
Technical field
The invention belongs to field of coal mining, is exactly specifically the outburst-prevention drill rod drawn out methane.
Background technology
Outburst-prevention drill rod, hole in coal seam exactly, then gas is extracted out by boring, effectively to utilize gas, and prevent the drilling rod of Gas Disaster, existing drilling rod is nearly all air inlet or water inlet from drilling rod, from giving vent to anger between drilling rod and hole wall or taking coal dust out of while water outlet, such working method, be easy to occur collapse hole after soft seam, can not effectively creep into, so the degree of depth of boring is little, the patent No. disclosed in Chinese patent is the patent of invention of 201020190784.6, although be give vent to anger in bar, but its venthole connecting portion blow-by, still there will be collapse hole phenomenon, moreover, its air inlet port must be arranged on the central axis of drilling rod, limit the position of air inlet port, it is uneven that fortune fortune water is imported and exported in easy appearance.
Summary of the invention
Object of the present invention, solving outburst-prevention drill rod in the past exactly can not effectively creep into, although or give vent to anger in bar and seal bad, unbalance in foreign trade and be unfavorable for the problem of coal dust by auger stem.
The present invention includes drilling rod body, drilling rod body at least arranges two axially extending bores.
Between the present invention's profit drilling rod, corresponding through hole sealing is communicated with.Namely sealing connection is junction sealing.
Axially extending bore of the present invention through hole is arranged on drilling rod center and forms centre bore, and other through hole moves towards in the shape of a spiral around around centre bore.
That pipe collar connects between drilling rod of the present invention.
Pipe collar one end of the present invention is stuck on drilling rod, and the pipe collar other end is threaded on drilling rod.
Between drilling rod of the present invention, alignment pin is set.
Alignment pin of the present invention refers to drilling rod junction, and through hole places projecting tube as alignment pin, another side through hole is arranged the dowel hole coordinated with projecting tube.
The number of axially extending bore of the present invention is one of two to six.
The invention has the advantages that good airproof performance, during use, entered as gas or water by one or two or three air inlets or water inlet, then discharge gas or water, while discharge gas or water by one or two or three exhausts or outfall, take the coal dust in bar out of, would not hole wall be destroyed, solve the problem of soft seam collapse hole, especially when holing, turn round after entering soft seam, use this patent more effectively can solve collapse hole.When establishing centre bore, when centre bore is as air inlet inlet opening, exhaust outlet hole is done in other hole, and when centre bore does exhaust outlet hole, air inlet inlet opening is done in other hole.Because steam vent moves towards around the helical form that centre bore is rifling, when drilling rod rotates, be conducive to the discharge of water or gas, be also conducive to the discharge of coal dust simultaneously.
