Description
Technical field
The utility model is related to the reserved filling air return system technical field in mine, and more particularly to a kind of mine is reserved to be filled back
Wind system air shaft.
Background technology
Exploiting field is the back production unit of pit mining, and each exploiting field is an independent mining operations area, and an exploiting field can
Constituted with by one or more faces.The normal back production in each exploiting field（Production）It has been both needed to endlessly fresh air
Each operating location of exploiting field is sent to supply operator breathing, dilution and exclude the various toxic and harmfuls in underground and mine dust, wound
Make environment in good ore deposit, ensure the healthy and labor safety of operating personnel in exploiting field.To supplying fresh sky in exploiting field
Gas and good air feed system are undivided.
At present, the air feed system of mining unit often uses both wings air intake, central exhaust ventilation mode, wherein, center
Extract out work be by air shaft realize, and air shaft be using chosen on stope or gallery under dig by the way of formed, and
By artificial making cement supporting, form what cement barrel was completed, due to production, stope or stoping operation plane it is continuous under
Drop, the height of air shaft is also being continuously increased, and now, the air shaft borehole wall is influenceed by ground pressure and mining exploitation so that in it
The cement barrel deformation failure in portion is serious, back wind resistance increase, has a strong impact on return air amount, and cement barrel is complete docile construction
Duct supporting builds what is built, it is impossible to modular replacing, therefore, can only again excavate structure ventilating system safe and efficient to ensure
Production, and ventilating system is rebuild, difficulty of construction is big, high cost.
The content of the invention
The utility model provides a kind of mine reserved filling air return system air shaft, for existing structure air shaft
Cement barrel be that the construction duct supporting of complete docile is built and built, it is impossible to modular replacing, in production process after coming into operation
In cannot maintenance and repair problem.
To achieve these goals, the technical solution of the utility model is specific as follows：
A kind of reserved filling air return system air shaft in mine, including cylinder, described cylinder is to be led to by four blocks of steel plates
Cross the rectangular structure that vertical angle steel head and the tail are welded to form, be provided with circular hole on four walls of described cylinder, the circular hole with
Transversal ventilation pipe correspondence is connected.
In order that cylinder is easily installed, repairs each other, angle cleat side is provided with described cylinder two ends edge
Circle, and it is provided with connecting hole in angle cleat square circle.
In order that cylinder can be connected with each other with the cooperating therewith air pipeline for using, on the circular hole on described cylinder
It is provided with Bolted angle connection ring, and Bolted angle connection ring and is provided with mounting hole.
Principle of the present utility model is：Cement barrel according to existing structure air shaft is complete docile construction duct branch
Shield builds what is built, it is impossible to the problem of modular replacing, and the cement barrel of tradition is designed as that four pieces of surfaces are provided with φ
The steel plate of the circular hole of 2.0m is welded into the square tube of 2012mm × 2062mm × 1700mm by vertical angle steel head and the tail, and in square tube
Upper and lower ends are provided with the angle cleat square circle with linkage function, for being fixedly connected between square tube, the circle in square tube
Bolted angle connection ring is set on hole, for the connection of this air shaft and transversal ventilation pipeline, when the air shaft borehole wall by press and
Mining exploitation influences so that after its air shaft deformation failure, and maintenance personal enters in the air shaft that air shaft will be damaged
Vertical angle steel from damage steel plate on pull down, then the steel plate of damage is pulled down from rectangular structure, change new steel plate,
It is welded and fixed again by vertical angle steel, realizes that the modularization of air shaft is changed.
The beneficial effects of the utility model are：The application of the present apparatus, greatly reduces filling method mine in reserved filling
Difficulty during air shaft, improves construction efficiency, reduces construction cost, and after construction terminates, the stability of a system preferably, is improved
The protection of air feed system, is mine safety efficiently produces the condition innovated, and with the increase of stope mining depth, by ground
Pressure is acted on and mining exploitation, and the deformation of vertical shaft can be repaired as soon as possible, reduce maintenance difficulties, which reduce flowing resistance,
Be conducive to Mine Safety in Production.

Specific embodiment
As shown in Figures 1 to 6, a kind of reserved filling air return system air shaft in mine, including cylinder 1, described cylinder
Body 1 is by the vertical angle steel rectangular structure that is welded to form of head and the tail, to be respectively provided with four walls of described cylinder 1 by four blocks of steel plates
There is circular hole, circular hole connection corresponding with transversal ventilation pipe is provided with angle cleat square circle 2 on the described two ends edge of cylinder 1,
And connecting hole is provided with angle cleat square circle 2, Bolted angle connection ring 3 is provided with the circular hole on described cylinder 1, and angle steel connects
Connect and be provided with mounting hole on ring 3.
This air shaft when in use, is put into and tunneled in the vertical shaft hole for completing by the utility model by hanging device,
According to hole depth, in putting some air shafts into hole successively, the angle cleat set using air shaft upper and lower ends
Square circle 2, some air shafts are interconnected by M10 bolts, are smeared sternly with cement at gap, anti-leak-stopping ash, keep ventilation perpendicular
Circular hole on well with and the transversal ventilation hole that is connected of vertical shaft hole it is corresponding, and using the Bolted angle connection ring 3 on circular hole with
Transversal ventilation pipeline in transversal ventilation hole is bolted.
When the air shaft borehole wall by press and influenceed with mining exploitation so that after its air shaft deformation failure, maintenance personal
Vertical angle steel in air shaft into air shaft first by damage is pulled down from the steel plate for damaging, then the steel plate that will be damaged
Pulled down from rectangular structure, change new steel plate, be welded and fixed again by vertical angle steel, realize the modularization of air shaft
Change.
