Abstract
The present invention relates to the coal mine gas pumping method of a kind of total length boring, it can efficiently solve increases the extraction time and strengthens the gas pumping method of extracting result, and this gas pumping method is that it can realize boring overall length and carry out extraction.It is to make three " petal " shape drill bits in the central authorities of traditional drill bit, when drill bit creeps into, three " petals " are combined into one, together creep into drill bit, at the end of boring, after drilling rod water-feed below unloads, exit one to two drilling rods, then extraction steel pipe is connected inside entrance boring from one section one section of drilling rod central authorities, three " petal " shapes of drill bit central authorities are backed down, with fixing powder stick, extraction steel pipe is fixed at the bottom of hole, then proceed to move back drilling rod, extraction steel pipe is stayed in whole boring, even if boring collapse hole has extraction steel pipe support can not affect the extraction of boring total length, steel mesh bedding is used above the extraction eye of extraction steel pipe, even if so collapse hole is also on extracting result impact seldom.
Description
Technical field
The present invention relates to coal mine gas exploitation and security fields, particularly one can increase the extraction time and
Strengthen the gas pumping method of a kind of underground coal mine total length boring of extracting result.
Background technology
At present, countries in the world coal mine gas extraction is to coal seam drilling, holes downwards from drill head several
The length that rice is long, seals boring and drainage tube, carries out extraction.This pumping method after drilling rod is extracted,
Hard coal seam is it is also possible to total length hole pumping and mining, and soft or projecting coal bed horse back is with regard to collapse hole, the most just
Take out the length of about 10 meters, remaining length of boring because of collapse hole can not extraction, shorten the extraction time, reduce
The extraction length of boring.Waste drilling length, waste drilling time, mechanical wear, electricity
Can consumption, even personal security, be badly in need of a kind of to increase the extraction time and strengthening a kind of complete of extracting result
The coal mine gas pumping method of long drilled holes.
Summary of the invention
For above-mentioned situation, the purpose of the present invention is to provide one can increase the extraction time exactly and enhancing is taken out
Adopt the gas pumping method of a kind of underground coal mine total length boring of effect, the underground coal mine watt of this total length boring
This pumping method is that it can realize boring overall length and carry out extraction.
The invention reside in it and make " petal " shape drill bit in the central authorities of traditional drill bit, when drill bit creeps into three
Individual " petal " is combined into one, and together creeps into drill bit, at the end of boring, and drilling rod water-feed below
After unloading, exit one to two drilling rods, then extraction steel pipe is connected entrance from one section one section of drilling rod central authorities and bore
Inside hole, three " petal " shapes of drill bit central authorities are backed down, with fixing powder stick, extraction steel pipe is fixed on hole
The end, then proceeding to move back drilling rod, extraction steel pipe is stayed in whole boring, even if boring collapse hole has extraction steel pipe to prop up
Support can not affect the extraction of boring total length, uses steel mesh bedding above the extraction eye of extraction steel pipe, even if so
Collapse hole is also on extracting result impact seldom.This pumping method substantially increases the utilization rate of coal bed drilling, right
Instruct coal mine gas drainage and keep the safety in production significant.Also reduce extraction cost simultaneously and improve people
Safety, be innovating greatly of coal mine gas drainage work, in coal mine gas drainage, popularization and application are got up
There is great social meaning and economic implications.

Fig. 5 is the present invention " petal " shape drill bit " petal " structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described in detail.
Being given by Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, the present invention is to be manufactured into " flower in normal drill bit central authorities
Lobe " shape drill bit, " petal " shape drill bit be made up of bit body (1), " petal " drill bit (4), bit body (1) by
Three external cutting sheets (8), three coolings apopore (3), the pivot pin (2) of three link " petal " drill bits and
Central authorities' cooling apopore (7) composition." petal " drill bit (4) is by three " petals ", three " petal " cooling
Apopore (5), cutting blade (6) form.
Extraction steel pipe (9) is stamped extraction eye (12) again by common steel pipe, the upper steel mesh (10) of outside welding in case
Collapse hole, extraction steel pipe one side is processed into screw (11), and another side is processed into nut (13), in order to extraction steel
Pipe is connected with each other.
During bit operation, " petal " drill bit (4) " petal " Guan Bi under the drive of bit body (1) is together crept into,
Stop when getting into projected depth creeping into, after boring terminates, after drilling rod water-feed below unloads, exit one and arrive
Two drilling rods, then connect the extraction steel pipe with steel mesh entrance boring from one section one section of drilling rod central authorities
Three " petals " of drill bit central authorities are backed down, are fixed at the bottom of hole by extraction steel pipe, so with fixing powder stick by face
After continue to move back drilling rod, extraction steel pipe is stayed in whole boring, though boring collapse hole have the extraction steel with steel mesh
Pipe supports the extraction that can not affect boring total length, because using steel mesh bedding, institute above the extraction eye of extraction steel pipe
Even if with collapse hole also on extracting result impact seldom.
This pumping method can realize the total length gas pumping of boring, and the extraction time is long, and extracting result is good, behaviour
Make simple, substantial amounts of manpower and materials can be saved, substantially increase coal bed gas extraction rate, safe and reliable, again
Gas can be extracted in a large number out utilization and the safety in production of gas resources are of great importance, present configuration is simple,
Novel, unique, also reduce extraction cost simultaneously and improve the safety of production environment, be that coal mine gas is taken out
One adopted innovates greatly, and popularization and application have great Social benefit and economic benefit.
