Abstract
The invention discloses a multi-stage hydraulic punching drill. A jet drill bit installed on the foremost side of a drill rod is provided with at least two symmetric jet nozzles which are communicated with a water channel of an inner cavity; and a drill rod under the jet drill bit is provided with at least one mechanical drill bit under which the drill rod is vertically fixed with a net-shaped tray, a jet device is fixed on the drill rod below the net-shaped tray and comprises at least two jet nozzles which are parallel to the drill rod and face rightly to the meshes of the net-shaped tray. According to the multi-stage hydraulic punching drill, the tray is arranged on the bottom of the drill rod by the multi-stage crushing and multi-stage punching technology so as to temporarily store the falling coals and avoid the coal stack due to continuous falling. The jet device installed in parallel under the tray continuously crushes the temporarily stored coals and the coal slurry continuously flows downwards along the periphery of the tray or through meshes of the tray so as to continuously discharge gas, so that the gas overrunning is avoided.
Description
Technical field
The present invention relates to field, a kind of colliery drilling tool, particularly a kind of multi-stage water power punching is bored.
Background technology
Hydraulic flushing in hole is mainly used in the boring of top, coal seam, and hydraulic flushing in hole is the important technology that increases coal-bed gas gas permeability, release, elimination outburst hazard, still; Present drilling rod and punching drill bit structure are simple, only at the drill bit position one group of jet nozzle are installed, if cherry coal; When water jet isolated coal body, a large amount of coal bodies were striden and are fallen in the boring, cause plug-hole easily; Because run of steel is big, causes the drilling rod stuck phenomenon easily; If than hard coal matter or dirt band, coal cinder that water jet isolates or spoil piece are difficult for fragmentation, cause plug-hole.To the dead situation of pipe becoming stuck, present processing mode is to strengthen hydraulic pressure, make pressure in the boring greater than the external world being that blocking portion is dredged.The boring of existing waterpower drilling rod is easily because of the coal cinder shutoff bore that drops diminishes, and often internal pressure is greater than external pressure.Strengthen hydraulic pressure in the boring and have great risk,, coal and gas spray orifice phenomenon occur, cause gas exceeding limit, increased risk, be unfavorable for the gas management when hydraulic pressure reaches threshold.
Summary of the invention
The objective of the invention is to bore exist simple in structure to existing water conservancy punching at present, cause coal body to collapse falling problems such as obstruction boring easily, provide a kind of rational in infrastructure, result of use is good, and the multi-stage water power punching that boring can not occur stopping up is bored.
Technical scheme: a kind of multi-stage water power punching is bored; Comprise drilling rod; Drill bit and jet mouth, drilling rod inner chamber are aquaporin, and the flow jet flow drill of the installed in front of drilling rod is provided with at least two symmetrical jet mouths; Jet nozzle is communicated with the inner chamber aquaporin, and the angle scope is 30 °≤α≤60 ° between the jet mouth of symmetry; At least one mechanical drill on the drilling rod below the flow jet flow drill; Vertical fixing has netted pallet on the drilling rod below the mechanical drill; The external diameter of netted pallet and each outside diameter approximately equal; On the drilling rod below the netted pallet, be fixed with ejector, this ejector contains at least two jet mouths parallel with drilling rod, and said jet mouth is over against the mesh of netted pallet.
A netted pallet at least vertically is installed on the drilling rod below the said ejector, is fixed with an ejector on the drilling rod of each netted pallet below, each ejector contains at least two parallel jet mouths, and said jet mouth is over against the mesh of netted pallet.
On the drilling rod between the adjacent netted pallet, a mechanical drill is installed at least.
Said ejector is a drill bit formula ejector, promptly in mechanical drill, sets out aquaporin, on drill bit, is symmetrically arranged with weep hole, and the jet mouth parallel with drilling rod is installed on each weep hole, and exhalant canal is communicated with drilling rod inner chamber aquaporin.
Said ejector comprises support and jet mouth, and the jet mouth is fixed on the support, and the jet mouth is communicated with drilling rod inner chamber aquaporin through water-supply-pipe.
Beneficial effect: the present invention adopts multiple stage crushing, and multistage punching technology is installed three drill bits on the first bar drill bar, and the jet mouth jet of first drill bit breaks coal, second, third drill bit Mechanical Crushing coal body; Can fully carry out fragmentation to coal cinder in the boring.At drilling rod bottom, tray, the coal breakage body that will collapse is stored in a warehouse temporarily, suppresses that coal body continues to collapse downwards and the generation of hoarding situation.The jet nozzle that is parallel to drilling rod is installed in bottom at pallet; This jet continues broken to entrepot coal storage body; The jet nozzle of tray bottom can carry out fragmentation and dilution to the coal cinder on the pallet, makes it along lasting outflow the in pallet periphery or the pallet mesh downwards, thereby gas is evenly gushed out continuously; Overcome the appearance of the situation of gas exceeding limit, prevented the outstanding generation that waits danger of gas.
