Description
Technical field
The present invention relates to the gas drainage technique in field, colliery, be specifically related to a kind of boring and take out integrated apparatus.
Background technology
Long-term buried underground, coal seam, its internal pressure is comparatively large, and the coal bed gas (gas) constantly produced is compressed in coal seam and is in stable state, but in working seam process, destroy the balance in coal seam, the high pressure gas gas be stored in coal seam unexpected outburst can out cause outstanding accident.Gas Outburst is a kind of serious disaster of underground coal mine, the safety in production in restriction colliery.On the other hand, because coal bed gas is partially sealed, be not easy under normal circumstances to be excluded, according to the stages of mining of specification, need before exploitation first to coal bed drilling with draw out methane.All the time, coal bed drilling all adopts the operation of metal drilling tool, pulls out drilling tool after boring, inserts releasing pipe and sealing of hole, utilizes extractor fan to carry out extraction, thus the coal bed gas (gas) of discharge depths, coal seam.Bit freezing and collapse hole problem can be run in reality boring and gas pumping process.Because drilling tool gos deep in coal seam, drilling rod lengthens piecemeal and can go deep into coal seam more than 60m, that so gos deep into coal seam creeps into work, once generation collapse hole, pipe becoming stuck enters depths, coal seam and cannot take out, metal drill pipe can not take out the normal work that can affect mining machines in time, thus affects carrying out smoothly of exploitation work, and process bothers very much.In addition, exiting in drilling rod process, more easily there is collapse hole phenomenon.Even if taken out smoothly by drilling rod, only local collapse hole also can affect the installation of gas drainage pipe, and boring is scrapped.Containing in the coal seam of coal bed gas, above two kinds of collapse holes are common phenomenons.Not only operating process is slowly complicated, and less effective, also can affect overall exploitation rate.
Summary of the invention
The object of the invention is for Problems existing and deficiency in existing gas discharge in mine process, provide a kind of brill of holing and bleeding of can effectively taking into account to take out integrated apparatus.
For achieving the above object, adopt following technical scheme: a kind of boring takes out integrated apparatus, comprise drilling rod and drill bit, and rig, it is characterized in that: described drilling rod is hollow PVC drilling rod, described drill bit is PVC drill bit, and PVC drilling rod is piecemeal by sealing docking, and the end seal of PVC drilling rod is connected on air extractor.
On described PVC drill bit, embed metal blade at drill lip position and form composite drill bit.The mode of setting-in can have multiple, such as: be provided with fin at the root of metal blade, drill bit pedestal arranges the groove of coupling, and fin is flush-mounted in after in groove and forms complex by heat seal process.
The interface of adjacent drill pipes is set with sealing ring, the sealing surface of adjacent drill pipes can be arranged annular groove, and sealing ring coupling is sleeved in the annular groove of both sides.
Can arrange chuck at drilling rod end, be set with circular base slab outside chuck, be set with circular flexible diaphragm seal in the outside of circular base slab, the external diameter of circular flexible diaphragm seal is greater than the external diameter of circular base slab, and is greater than the external diameter of boring.Aspirating hole can also be set in described PVC drilling rod side.
Beneficial effect: the present invention utilizes PVC drilling rod and PVC drill bit as disposable boring bar tool, directly stays in boring, as gas drainage pipe after drilling rod and bit operation.Because the seam hardness in coal mining field is limited, be enough to the working strength of bearing coal bed drilling as the PVC drilling rod of disposable drilling tool and drill bit.
Be positioned at the aspirating hole on PVC drilling rod, carry out blowing or bleeding when being not only conducive to boring, be more conducive to the air inlet port as gas drainage under suction.
Drilling rod as gas drainage pipe, is simplified gas drainage under suction operation by the present invention, directly can draw out methane to after drilling rod sealing pores.The collapse hole phenomenon forming boring because moving back drill-through journey can be avoided.Even if the collapse hole because of boring procedure once in a while, the drilling rod of PVC material and drill bit can not form obstacle to exploitation, thus do not affect mining progress.Visible, the present invention is easy and simple to handle, efficiency is high, effective, can cost of winning be reduced, not affect mining progress, very be beneficial to promotion and implementation.

Detailed description of the invention
Embodiment 1: a kind of boring takes out integrated apparatus, see Fig. 1 and Fig. 2, hollow PVC drilling rod 2 is carried PVC drill bit 1 hole to depths, coal seam, when boring reaches target location (such as 60m), again sealing pores is carried out to PVC drilling rod 2, traditional sealing of hole means can be adopted to carry out sealing pores to PVC drilling rod.
Hollow PVC drilling rod 2 is used as gas drainage pipe.The end seal of PVC drilling rod 2 is connected on air extractor 10, utilizes air extractor 10 pairs of bore inner to carry out gas drainage under suction work.
Described PVC drilling rod 2 can, piecemeal by sealing docking, make it constantly to be extended, till piercing correct position.The interface of adjacent PVC drilling rod 2 preferably arranges sealant, such as, be set with sealing ring 3, the sealing surface of adjacent drill pipes can be arranged annular groove 24 and 25, and sealing ring 3 coupling is sleeved in both sides annular groove 24 and 25.
In the present embodiment, select the hardness requirement of PVC drill bit 1, make itself and institute's working seam hardness reach optimum value, the working strength making the PVC drilling rod 2 of disposable drilling tool and PVC drill bit 1 be enough to bear coal bed drilling requires to be as the criterion.
In order to reach the effect that draws out methane preferably, aspirating hole 4 can also be set in the side of described PVC drilling rod 2.This aspirating hole 4 carries out blowing or bleeding when being not only conducive to boring, is more conducive to the air inlet port as gas drainage under suction.Connector 11 can be fixed connector, and the gas pumping after only shutting down for rig 12 connects.Also can be rotary connecting joint, to the inflation of boring malleation while rig 12 works, or negative pressure ventilation.
Embodiment 2: on embodiment 1 method basis, improves described PVC drill bit, see Fig. 3, embeds metal blade 9 form composite drill bit at drill lip position.Such as can be provided with fin at the root of metal blade, and arrange the groove of coupling on drill bit pedestal, fin is flush-mounted in after in groove and forms complex by heat seal process.
Embodiment 3: see Fig. 2, on embodiment 1 basis, provide a kind of hole sealing structure that can start to install, an i.e. movable installation hole packer on least significant end drilling rod, this hole packer is in a drilling rod end movable installation chuck 5 according to actual needs, circular base slab 6 is set with outside chuck, circular flexible diaphragm seal 7 is set with in the outside of circular base slab, circular base slab and boring are quite or be greater than boring, the external diameter of circular flexible diaphragm seal is greater than the external diameter of circular base slab, and be greater than the external diameter of boring, thus when bleeding to PVC drilling rod, air pressure inside is lower than external pressure, circular flexible diaphragm seal is inwardly inhaled, gluing, sealing is near boring.
Embodiment 4: see Fig. 4, on embodiment 3 basis, circular base slab both can be sheet also can be spherical support plate, the arranged outside of spherical support plate groove 8 or outer plate, be convenient to sealing and install circular flexible diaphragm seal, circular flexible diaphragm seal also can be arranged to the sphere flexible sealing fin of mating with spherical support plate.
