Description
Technical field
The invention belongs to mine leting speeper technical fields, and it is efficient to adopt the aqueous roadway in the roof of mud stone more particularly to one kind
Leting speeper method and device.
Background technique
In practice, if Strata Overlying The Seam has a water-bearing layer, overlying rock is broken mine construction when working face extraction, inevitable
Cause aquifer water to pour into working face, or even generate discharge disaster, therefore needs leting speeper before exploiting, it is in advance that top plate is aqueous thin
Row.But traditional leting speeper technology mainly uses same casing, it is difficult to cope with the concrete condition of different layers position rock stratum, deep casing
Easily cause blocking during leting speeper, and the hydrophobic effect very little that middle part is played with the casing of hole, often make
At unnecessary waste, superficial part is easy to be squeezed and deformed casing due to the huge rock deformation pressure in plastic zone.Meanwhile shortage is easy to
The reasonable bore angle of leting speeper and roadway surrounding rock control.This patent is directed to above situation, and back is divided into shallow workings
Country rock plastic rupture area, stablize rock stratum area and deep aquifers area at middle part, and three kinds of subregions use various forms of casings, realizes high
While imitating waterproof, the stabilization of roadway surrounding rock is also ensured.
Summary of the invention
It is an object of the invention to provide one kind to adopt the efficient leting speeper method and device of the aqueous roadway in the roof of mud stone, visits in mine
During discharging water, back is divided into shallow workings country rock plastic rupture area, rock stratum area and deep aquifers area are stablized in middle part,
Three kinds of subregions use various forms of casings, go to solve the problems, such as different situations corresponding.
The technical solution adopted by the present invention to solve the technical problems is：
One kind adopting the efficient leting speeper method of the aqueous roadway in the roof of mud stone, and back is divided into shallow workings country rock plastic rupture
Area, stablize rock stratum area and deep aquifers area at middle part, and three kinds of subregions use various forms of casings, drills and creeps into leting speeper
When, bore angle is consistent with plastic zone depth capacity, has reached and preferably discharges water effect and prevent tunnel superficial part plastic rupture country rock
Ponding.
It is such to adopt the efficient leting speeper method and device of the aqueous roadway in the roof of mud stone, for shallow workings country rock plastic rupture
Area, jacket exterior setting longitudinal rib prevent from being bent in drilling process, while preventing under huge plastic deformation pressure equipped with circle rib
It is squeezed and deformed, while being evenly arranged hole in sleeve surface and being easy to water body outflow.For middle part stablize rock stratum area it is aqueous compared with
It is few, directly prevent deep well drilling process middle sleeve to be bent in jacket exterior setting longitudinal rib, sleeve surface not apertured hole, is smooth tube
Wall, to maximally reduce the frictional force of tube wall and hole wall.Larger for deep aquifers area water content, sleeve surface is uniform
Arrangement hole is flowed out by water body, and bore hole size and density are all larger than the bore hole size in shallow workings country rock plastic rupture area and close
Degree, meanwhile, outside setting longitudinal rib prevents drilling process middle sleeve to be bent.
It is such to adopt the efficient leting speeper method and device of the aqueous roadway in the roof of mud stone, the internal surface of sleeve pipe of arrangement hole is added
Add built-in strainer, the shale rock mass or debris blockage internal pipeline after preventing softening, while permeable effect is played again.Casing two
End is equipped with matching thread, realizes the connection of drilling rod, while casing one end is provided with extra stretching, so that casing docks and avoids
Shale rock mass or landwaste enter screw thread and hinder connection.
Beneficial effects of the present invention：
Back the characteristics of for back different layers position rock stratum, is divided into three by such efficient leting speeper method and device
Kind, three kinds of subregions are using various forms of casings, it can be achieved that the high efficiency and duration of leting speeper.
The jacket exterior setting longitudinal rib in shallow workings country rock plastic rupture area prevents from being bent in drilling process, while being equipped with circle
Rib prevents from being squeezed and deformed it under huge plastic deformation pressure.The jacket exterior setting longitudinal rib that rock stratum area is stablized at middle part prevents
The bending of deep well drilling process middle sleeve, sleeve surface not apertured hole are smooth tube wall, and structure is relatively easy, cost-saved.It is deep
The sleeve surface of portion's intake area is evenly arranged hole and flows out by water body, and bore hole size and density are all larger than shallow workings country rock
The bore hole size and density in plastic rupture area, to realize high-effective water-proof.Meanwhile being equipped with the built-in filter of hole internal surface of sleeve pipe addition
Net, shale rock mass or debris blockage internal pipeline after preventing softening, while permeable effect is played again.
Detailed description of the invention

Portion's intake area 1, three kinds of subregions use various forms of casings, when leting speeper drills and creeps into, 4 angles that drill and shallow workings
3 depth capacity direction 5 of country rock plastic rupture area is consistent, and plastic zone maximum cracking depth direction 5 is tested by mining induced stress by managing
By being calculated, has reached and preferably discharge water effect and prevent tunnel superficial part plastic rupture country rock ponding.
Deep casing is used in deep aquifers area 1,14 one end of casing is connected with drill bit 16, and the other end is provided with interior spiral shell
Line 12 and have it is extra stretch out 11, facilitate connect other casings, 14 surface of casing, which is evenly arranged hole 15, allows water body to flow out, hole
15 sizes and density are all larger than 10 size of hole and density in shallow workings country rock plastic rupture area 3, and the built-in filter of inner wall addition
Net 17, shale rock mass or debris blockage internal pipeline after preventing softening, while permeable effect is played again, meanwhile, outside is set
Setting longitudinal rib 9 prevents drilling process middle sleeve to be bent.
Stablize at middle part and use medial sleeve in rock stratum area 2, one end and deep by casing 13 with external screw thread 6 are aqueous
The internal screw thread 12 of casing 14 in floor area 1 is connected, and the other end is also equipped with internal screw thread 12 and has extra stretching 11, outside casing 13
Portion's setting longitudinal rib 9 prevents deep well drilling process middle sleeve to be bent.
Superficial part casing is used in shallow workings country rock plastic rupture area 3, one end by casing 8 with external screw thread 6 and
The internal screw thread 12 that the casing 13 in rock stratum area 2 is stablized at middle part is connected, and the other end is also equipped with internal screw thread 12 and has extra stretching
11, facilitate the extra casing of connection, setting longitudinal rib 9 prevents from being bent in drilling process outside casing 8, while preventing equipped with circle rib 7
It is squeezed and deformed under huge plastic deformation pressure, while being evenly arranged hole 10 on 8 surface of casing and being easy to water body outflow, together
When inner wall add built-in strainer 17, the shale rock mass or debris blockage internal pipeline after preventing softening, while playing again permeable
Effect.
As described above, embodiments of the present invention are described in detail, as long as but essentially without this hair of disengaging
Bright inventive point and effect belongs to infringement, and the present invention can have many deformations, this is to one skilled in the art
Obviously.Therefore, such variation is also integrally incorporated within protection scope of the present invention.
