Abstract
The invention discloses a coal seam drilling hole-collapse preventing lower sleeve device capable of drilling along with a drill and a drilling method. The device is particularly formed by a cavel drill (1), a hose bit (2), a combined propelling device (3), a mesh sleeve (4) and a twisting drill rod (5). According to the coal seam drilling hole-collapse preventing lower sleeve device, in the drilling process of the drill and the drilling process of the twisting drill rod, the combined propelling device (3) is utilized to drive the mesh sleeve (4) and the hose bit (2) to rotate together, and consequently drilling of the twisting drill rod and coal breaking drilling of the hose bit are simultaneously carried out so as to drive the mesh sleeve to drill into a coal hole. When the coal hole reaches a predetermined depth, the twisting drill rod is retreated from the interior of the sleeve, and the mesh sleeve is left in the coal hole. Therefore, the coal seam drilling hole-collapse preventing lower sleeve device plays a role in preventing the coal hole from collapsing and avoids the occurrence of the condition that the drill hole is obsolete.
Description
Technical field
The present invention relates to the easy collapse hole of coal bed drilling and study with the device that creeps into lower sleeve, belong to the safety of coal mines field, be applicable to than the soft seam easy collapse hole of boring and cause under the invalid condition of boring, utilize sleeve to carry out the method for guard aperture, often use under coal mine.
Background technology
As everyone knows, after carrying out coal bed drilling in weak seam, be easy to occur collapse hole.Substantially in removing the process of brill, collapse hole will occur exactly, this just usually causes various measures holes invalid, thereby has had a strong impact on the safety in production in colliery.At present the method for the anti-collapse hole of coal bed drilling is exactly first to beat the coal hole substantially, cement injection fast then, then carry out cleaning bottom of hole, but such method is in the situation that coal seam conditions is softer just cannot realize at all, as long as remove brill, the hole just blocks, and has little time slip casting at all.
Summary of the invention
For the problems referred to above, purpose of the present invention is exactly will make the anti-collapse hole of weak seam boring to creep into the device of lower sleeve with brill.To guarantee the validity of various measure borings under the weak seam condition.
The object of the present invention is to provide the anti-collapse hole of a kind of coal bed drilling to creep into the lower sleeve device with brill, this device is softer for being used for the coal seam coal body, the coal bed drilling anti-collapse hole of boring under can not condition of molding crept into the device of lower sleeve, the anti-collapse aperture apparatus that mainly is comprised of goat's horn drill bit (1), hosqe bit (2), combination propulsion plant (3), mesh sleeve (4), twist drill rods (5) with brill;
At twist drill rods (5) top connection goat's horn drill bit (1), to make up simultaneously propulsion plant (3) is fixed on twist drill rods (5), hosqe bit (2) is connected with mesh sleeve (4), and be inserted in hosqe bit (2) and the rotation that assembles from goat's horn drill bit (1) front side, the inner clamp of combination propulsion plant (3) and hosqe bit is flexibly connected.
Further, in described anti-collapse aperture apparatus, goat's horn drill bit (1) and twist drill rods (5) can freely be extracted out from sleeve after playing finishing drilling.
Further, in described anti-collapse aperture apparatus, mesh sleeve (4) can be used the screwed union spreading.
Another object of the present invention is to provide a kind of boring method of weak seam, this boring method comprises the following steps:
Utilizing combination propulsion plant (3) to drive mesh sleeve (4) hosqe bit (2) in the process that twist drill rods creeps into rotates together, thereby when forming spiral bit and creep into the sleeve drill bit simultaneously broken coal borer advance, drive thus the mesh sleeve with creeping among coal inlet, when reaching desired depth, withdraw from twist drill rods from sleeve inner, the mesh sleeve is stayed among the coal hole, thereby played the effect that prevents coal hole collapse hole.
The present invention has used in the process that drill bit creeps into, utilizing combination propulsion plant (3) to drive mesh sleeve (4) hosqe bit (2) in the process that twist drill rods creeps into rotates together, thereby when forming spiral bit and creep into the sleeve drill bit simultaneously broken coal borer advance, drive thus the mesh sleeve with creeping among coal inlet, when reaching desired depth, withdraw from twist drill rods from sleeve inner, the mesh sleeve is stayed among the coal hole, thereby both played the effect that prevents coal hole collapse hole, the situation of cancelling of avoiding again holing occurs.
Description of drawings
Fig. 1 is that the anti-collapse hole of weak seam boring provided by the invention is with the structure chart that bores drilling apparatus.
The specific embodiment
The present invention will be described below in conjunction with drawings and Examples.
As shown in Figure 1, the anti-collapse hole of weak seam boring that provides of the embodiment of the present invention specifically is comprised of goat's horn drill bit (1), hosqe bit (2), combination propulsion plant (3), mesh sleeve (4), twist drill rods (5) with boring drilling apparatus.
At twist drill rods (5) top connection goat's horn drill bit (1), to make up simultaneously propulsion plant (3) is fixed on twist drill rods (5), hosqe bit (2) is connected with mesh sleeve (4), and be inserted in hosqe bit (2) and the rotation that assembles from goat's horn drill bit (1) front side, the inner clamp of combination propulsion plant (3) and hosqe bit is flexibly connected.
In anti-collapse aperture apparatus, goat's horn drill bit (1) and twist drill rods (5) can freely be extracted out from sleeve after playing finishing drilling.
The present invention also provides a kind of boring method of weak seam, and this boring method comprises the following steps:
Utilizing combination propulsion plant (3) to drive mesh sleeve (4) hosqe bit (2) in the process that twist drill rods creeps into rotates together, thereby when forming spiral bit and creep into the sleeve drill bit simultaneously broken coal borer advance, drive thus the mesh sleeve with creeping among coal inlet, when reaching desired depth, withdraw from twist drill rods from sleeve inner, the mesh sleeve is stayed among the coal hole, thereby played the effect that prevents coal hole collapse hole.
The above is only preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., within all should being included in protection scope of the present invention.
