Description
Technical field
The present invention relates to technical field of coal mine, and in particular to a kind of three holes for meeting underground release, leting speeper, gas drainage under suction
And use construction method.
Background technology
In process of coal mining, bump, water, gas are 3 more prominent the Nature disasters, and working face is tunneled and returned
Adopt and must comply with " driving, not release are not tunneled after first release ", " having to doubt must visit, first visit and dig afterwards, meet pick that must visit " and " first after pumping
Adopt, monitoring, with wind fixed output quota " principle, release, to visit water and gas drainage under suction realized by construction drill.Current release
Pressure relief vent of constructing is needed, visiting water needs spy water hole of constructing, and gas drainage under suction needs gas extraction hole of constructing, three kinds of brills of constructing respectively
Hole, workload is bigger, and time-consuming, and the staff of use is relatively more.
The content of the invention
The present invention provide it is a kind of meet underground release, leting speeper, three holes of gas drainage under suction and with construction method, can realize
One hole three is used, convenient and efficient.
It is existing in the prior art to solve the problems, such as, the technical scheme is that：It is a kind of meet underground release, leting speeper,
Three holes of gas drainage under suction and with construction method, it is characterised in that：The method and step is：
1）Construction drill site：It constructs on the right side of digging laneway a triangle drill site；
2）It constructs and uses hole：The construction 1 and with hole on the side of drill site and parallel length of meeting head on, and be 120- with hole aperture
150mm, hole depth 100-180m, and be 6-10 ° with the angle in hole and digging laneway；
3）Lower two level casing：When hole is constructed to 20m, two level casing, the length of two level casing are set in hole
Spend for 20m, a diameter of 89-146mm, to two level casing and and with slip casting between hole, make two level casing with and be condensed into one with hole
It rises, continues to construct and with hole, construction arrives and with after hole depth, and with the stress distribution of hole change coal body herein, stores coal body
Energy slowly discharged, achieved the purpose that release, if there is water in coal body herein, water is flowed out from and with hole, is reached
The purpose of leting speeper；
4）Lower screen casing：And constructed with hole to depth, if not there are flowing out, meet the condition of gas drainage under suction, at this time
Screen casing, a diameter of 50-60mm of screen casing or so can be installed to and with hole, length is in 40-60m；
5）Polyurethane hole packer sealing of hole：Screen casing is installed to and with after the 40-60m depth of hole, pair and with hole polyurethane sealing of hole,
Polyurethane is uniformly applied on gunnysack, smearing while is wrapped in gunnysack on hole packer rapidly, then hole packer is sent into simultaneously
It is expanded in hole, treating polyurethane that chemical reaction occurs, so as to achieve the purpose that sealing of hole, hole sealing depth 5m, sealing of hole terminates, just
It can carry out coal bed gas drainage.
The drill site height is consistent with head-room, and a length of 7m of a side that drill site is communicated with tunnel, another with meeting
Head parallel length is 5m, a length of 9m in another side.
Compared with prior art, advantages of the present invention is as follows：A hole three of the invention is used, convenient and efficient, is reduced and is unloaded in construction
It presses hole, visit water hole, the expense on gas extraction hole, improve construction efficiency, time, manpower are saved, for coal mining preparation work.
Description of the drawings
Fig. 1 is drill site and with hole, two level casing layout drawing in the method for the present invention
Reference sign：In figure：1- drill sites, 2- and with hole, 3- two level casings.
Specific embodiment
The design is described in detail below in conjunction with the accompanying drawings：
Referring to Fig. 1：Meet underground release, leting speeper, three holes of gas drainage under suction and with construction method step be：
1）Construction drill site：It constructs on the right side of digging laneway a triangle drill site 1,1 height of drill site is consistent with head-room, bores
The a length of 7m of a side that field 1 is communicated with tunnel, another with parallel length of meeting head on for 5m, a length of 9m in another side；
2）It constructs and uses hole：The construction 1 and with hole 2 on the side that 1 length of drill site is 5m, and be 120- with 2 aperture of hole
150mm, hole depth 100-180m, and be 6-10 ° with the angle of hole 2 and digging laneway；
3）Lower two level casing：When hole 2 is constructed to 20m, two level casing 3, two level casing 3 are set in hole 2
Length for 20m, a diameter of 89-146mm, to two level casing 3 and and use slip casting between hole 2, make two level casing 3 and and with hole 2
It being condensed into together, continues to construct and with hole 2, construction arrives and with after 2 depth of hole, and changes the stress distribution of coal body herein with hole 2,
The energy that coal body stores is made slowly to be discharged, has achieved the purpose that release, if there is water in coal body herein, water is from and with hole 2
Outflow, has achieved the purpose that leting speeper；
4）Lower screen casing：And constructed with hole 2 to depth, if not there are flowing out, meet the condition of gas drainage under suction, at this time
Screen casing, a diameter of 50-60mm of screen casing or so can be installed to and with hole 2, length is in 40-60m.
5）Polyurethane hole packer sealing of hole：Screen casing is installed to and with after the 40-60m depth of hole, pair and use polyurethane sealing with hole 2
Polyurethane is uniformly applied on gunnysack by hole, and smearing while is wrapped in gunnysack on hole packer rapidly, then hole packer is sent into
And expanded in hole 2, treating polyurethane that chemical reaction occurs, so as to achieve the purpose that sealing of hole, hole sealing depth 5m, sealing of hole knot
Beam, it is possible to carry out coal bed gas drainage.
Invention of the present invention can save equipment, material investment expense, only need to utilize original pressure relief vent construction equipment, material and
Original spy water orifice device is not required to additional procuring equipment, material, no other inputs；
The present invention can create considerable economic benefit：Before being not used, fully mechanized workface need to meet head on leting speeper in advance, leting speeper
Drill 450 yuan/m,, will according to leting speeper on the basis of " dig-unload " parallel operations are realized by the research application of the technology
It asks and is designed, the requirement of leting speeper is met while release.Since the technology successful implementation, coal roadway tunneling has been completed
5052m, accumulative minimizing leting speeper drill footage 5760m.Simple construction leting speeper drilling unit price was 150 yuan/m, by 2015
It only saves leting speeper fund and has reached 150*5760=86.4 ten thousand yuan December.
