Abstract
The invention belongs to the field of coal exploitation, particularly relates to an outburst-resisting drill stem for draining gas, and aims at solving the problem that the existing outburst-resisting drill stem can not drill effectively, or although gas is drained from the inside of the stem, sealing is poor, and an inlet and an outlet are not balanced. The alveolate drill stem comprises a drill stem body which is at least provided with two axial through holes. When the drill stem begins to do drilling work, two drill stem bodies are connected together through a pipe hoop. A drill stem I locates the pipe hoop, and the pipe hoop is threaded with a drill stem II. The alveolate drill stem has the advantages of being good in sealing performance and simultaneously solving the problem of hole collapsing of a soft coal layer.
Description
Technical field
The invention belongs to field of coal mining, specifically is exactly the protrusion-dispelling drilling rod of usefulness of drawing out methane.
Background technology
The protrusion-dispelling drilling rod is holed in the coal seam exactly, extracts gas out through boring then, effectively to utilize gas; And prevent that the drilling rod of gas disaster, existing drilling rod from nearly all being air inlet or water inlet from drilling rod, from giving vent to anger between drilling rod and the hole wall or taking coal dust water outlet the time out of; Such working method is easy to occur the hole of collapsing behind soft seam, can not effectively creep into; So the degree of depth of boring is little, the disclosed patent No. of Chinese patent is 201020190784.6 patent of invention, though be in bar, to give vent to anger; But its venthole connecting portion blow-by still the hole phenomenon of collapsing can occur, moreover; Its air inlet port must be arranged on the central axis of drilling rod, has limited the position of air inlet port, and it is uneven to occur importing and exporting fortune fortune water easily.
Summary of the invention
The object of the invention solves exactly in the past that the protrusion-dispelling drilling rod can not effectively creep into, though the problem of perhaps giving vent to anger in the bar and sealing bad, unbalance in foreign trade and being unfavorable for coal dust through auger stem.
The present invention includes the drilling rod body, the drilling rod body is provided with two axially extending bores at least.
Corresponding through hole sealing is communicated with between the sharp drilling rod of the present invention.It is the junction sealing that i.e. sealing is communicated with.
Through hole of axially extending bore of the present invention is arranged on the drilling rod center and constitutes centre bore, and other through hole is around around centre bore shape trend in the shape of a spiral.
Be that pipe collar connects between the drilling rod of the present invention.
Pipe collar one end of the present invention is stuck on the drilling rod, and the pipe collar other end is threaded on the drilling rod.
Between the drilling rod of the present invention alignment pin is set.
Alignment pin of the present invention refers to the drilling rod junction, on one side through hole place projecting tube as alignment pin, the dowel hole that cooperates with projecting tube is set on the another side through hole.
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, advance like gas or water by one or two or three air inlets or water inlet; Discharge gas or water by one or two or three exhausts or outfall again, when discharging gas or water, take the coal dust in bar out of; Just can not destroy hole wall, solve the collapse problem in hole of soft seam, especially when boring; Turn round behind the entering soft seam, use this patent can more effectively solve the hole of collapsing.Establishing under the situation of centre bore, centre bore is during as the air inlet inlet opening, and the exhaust outlet hole is done in other hole, and when centre bore was done the exhaust outlet hole, the air inlet inlet opening was done in other hole.Because steam vent moves towards around the helical form that centre bore is rifling, during the drilling rod rotation, help the discharge of water or gas, also help the discharge of coal dust simultaneously.
