Description
Technical field
The invention belongs to mine ventilation system Treatment process field, and in particular to a kind of underground mine goaf large area is leaked
Wind administering method.
Background technology
In some old mines, pressed and shown due to long-term open-stope method random mining and mine, ventilating system locally occurs
The main tunnel of ventilation and goaf cave in insertion the fact, resulting goaf large area is leaked out extremely serious, causes ore deposit
Well ventilating system can dominate air quantity and drastically reduce.Goaf large area is leaked out there is the passage that leaks out is more, blocks the characteristics of difficult,
Most mines are often left out of account when in face of such a situation, or dig main tunnel of divulging information again, spend cost huge.
The content of the invention
It is an object of the invention to provide a kind of underground mine goaf large area air-leakage control method, deposited for underground mine
Goaf large area Air Leakage, the way in leak out closure or the new pick tunnel of abandoning tradition, it is proposed that a kind of cost is low,
Fast, new method is administered in efficient goaf air leaking section repairing, solve very well goaf large area leak out it is existing leak out it is logical
The problem of road closure is difficult, newly pick tunnel cost is too high.
The purpose of the present invention is achieved through the following technical solutions：
A kind of underground mine goaf large area air-leakage control method, using setting up airflow channel by intake and air-out
Tunnel is docked in goaf, and airflow channel is carried out with the junction in intake and air-out tunnel using masonry fire dam is built by laying bricks or stones
Sealing linking, realize the transition leap of the distinguished and admirable section of being leaked out in goaf large area in underground.
Described airflow channel is bundled on support by multiple hard ventilating tube groups and is made, and each hard ventilating tube group is hard by more piece
Matter air duct is linked in sequence along hard ventilating tube long axis direction and formed.
Described support is anchored in gob floor using cement roll Anchor Agent.
Beneficial effects of the present invention：
The present invention be directed to large area Air Leakage in goaf existing for underground mine, proposes that a kind of cost is low, quick, high
The goaf air leaking of effect administers new method, is easy to implement commercial Application, solves goaf large area very well and leaks out existing leakage
The problem of wind passage plugging is difficult, newly pick tunnel cost is too high.Most of all, it uses the technique of air duct composite assembly, tool
There is simple to operate, practicality and high efficiency, obturation effect is good, solves the large area air-leakage control problem in old goaf very well.
Brief description of the drawings
Fig. 1 show large area air-leakage control process schematic in goaf of the present invention.
Fig. 2 is hard ventilating tube group of the present invention and fire dam junction A-A directional profile figures.
Fig. 3 is airflow channel B-B directional profile figures in dead zone of the present invention.
Wherein：1 intake；2 hard ventilating tube groups；3 cave in gob edge；4 goaf air leaking points；5 masonry fire dams；
6 air-out tunnels；7 supports；8 support anchored ends；9 gob floors.
Embodiment
As shown in drawings, arrow expression wind direction, caving between intake 1 and air-out tunnel 6 are mined out in figure
Have goaf air leaking point 4 at three on area border 3, using set up airflow channel by intake 1 and air-out tunnel 6 in goaf
Docking, airflow channel and the junction in intake 1 and air-out tunnel 6 are connected using building masonry fire dam 5 by laying bricks or stones and carry out sealing, reality
The transition leap of the distinguished and admirable section of being leaked out in goaf large area in existing underground.
Described airflow channel is bundled on support 7 by four hard ventilating tube groups 2 and is made, and each hard ventilating tube group 2 is by more
Section hard ventilating tube is linked in sequence along hard ventilating tube long axis direction to be formed.
The support anchored end 8 of described support 7 is anchored in gob floor 9 using cement roll Anchor Agent.
Its specific implementation method is as follows：
1st, the making of airflow channel：Mine ventilation tunnel specification is generally 2.2m × 2.3m, from multiple external diameter specifications
800mm, length 1m steel and plastic composite material hard ventilating tube along hard ventilating tube long axis direction be linked in sequence make one group of hard
Air duct group 2, hard ventilating tube group 2 make four groups altogether；
2nd, the round steel center vertical welding that support 7 is 16mm with 2 1.6m length, external diameter forms, and support 7 is in airflow channel side
One support anchored end 8 is set every 1m upwards, support 7 is anchored in by gob floor 9 using cement roll；
3rd, four hard ventilating tube groups 2 are bundled on support 7 paragraph by paragraph with external diameter 8mm iron wire and just completed across goaf
Set up airflow channel；
4th, airflow channel and the use of the junction in intake 1 and air-out tunnel 6 build masonry fire dam 5 by laying bricks or stones and carry out sealing rank
Connect, the outer layer of masonry fire dam 5 uses cement sand plaster, ensures the sealing with the link position of hard ventilating tube group 2.
If setting up route runs into turning, in order to ensure the gentle transition of airflow channel, use and hard at turning
The steel and plastic composite material bent angle arcuate member connection hard ventilating tube of air duct phase same material, so as to realize that hard ventilating tube group 2 can be along
The angle of turning gently passes through.
Due to being related to operation in old goaf, Contraction in Site should be carried out in the case where ensureing safety, before operation
Carry out operating area safety verification.
