Abstract
The utility model relates to a ventilation facility in colliery specifically is a colliery is binary channels high -low pressure air door ventilation system in pit, including first air door partition wall (1) and the second air door partition wall (2) that is located the return air lane, first, two air door partition walls (1, 2) are gone up to correspond and have been offered pedestrian's runway air door (4) and wind channel window (5), build third air door partition wall (3) between first air door partition wall (1) and the second air door partition wall (2) by laying bricks or stones, third air door partition wall (3) is gone up to correspond and has been offered pedestrian's runway air door (4) and wind channel window (5), separate pedestrian's runway and wind channel through building stopping (6) by laying bricks or stones between first air door partition wall (1) and the third air door partition wall (3). The utility model relates to a rationally, through the improvement to mine air damper and adjust the improvement of wind window, fine solution the air door open the difficulty, damage easily, the easy crowded person of hurting sb. 's feelings or even cause injured and fatality, air door to open defects such as in -process amount of wind unstability.
Description
Technical field
The utility model is related to coalmine ventilation facility, specially a kind of underground coal mine binary channels high-low pressure air door ventage
System.
Background technology
At present, underground coal mine return airway is provided with damper ventilating system, as shown in figure 1, ventage in return airway
System is provided with twice, including the first air door partition wall 1 and the second air door partition wall 2, and correspondence is offered on first and second air door partition wall 1,2
Pedestrian's runway air door 4 and air channel window 5.
Due to the damper for regulating and controlling main air entering and returning lane air quantity under mine exist damper both sides leeway and drift it is excessive,
Air door switch is difficult, wind speed is too high, and pedestrian is careless slightly to be easy for blowing down, easily occurs air door personal injury, air door at closing time
The hidden danger such as difficult in maintenance is easily damaged, to solve the above problems, decision is transformed former damper.
The content of the invention
The purpose of this utility model is that original return airway damper is transformed, and solves the problems, such as it.
The utility model adopts the following technical scheme that realization：
A kind of underground coal mine binary channels high-low pressure air door ventilating system, including the first air door partition wall in return airway and
Second air door partition wall, correspondence offers pedestrian's runway air door and air channel window on the first and second air door partition wall.
The 3rd air door partition wall is built between the first air door partition wall and the second air door partition wall by laying bricks or stones, on the 3rd air door partition wall
Correspondence offers pedestrian's runway air door and air channel window.
By building stopping by laying bricks or stones by pedestrian's runway and air channel between the first air door partition wall and the 3rd air door partition wall
Separate；Similarly, by building stopping by laying bricks or stones by pedestrian's runway and wind between the second air door partition wall and the 3rd air door partition wall
Road separates.
Think that former damper pedestrian runway is shared with air channel, according to flowing resistance law H=RQ2, so air door
There is leeway and drift in both sides.It is the increase for reducing air door both sides leeway and drift, eliminating air quantity during door opening, need to be by pedestrian
Runway is isolated with air channel with brick wall, carries out binary channels, while increasing by one air door in centre, can so substantially reduce wind
Resistance, carries out high-low pressure.In the big lane regulation of main return air first using binary channels high-low pressure regulation facility, pedestrian's driving is substantially increased
Security.
Compared with prior art, advantage specific as follows：
1st, the regulation of binary channels high-low pressure is carried out first to implement.
2nd, construct simple, pedestrian's driving is convenient, flexible.
The utility model is reasonable in design, by improvement and the improvement of regulation wind window to mine damper, solves well
Having determined, door opening is difficult, be easily damaged, easily squeeze the person of hurting sb.'s feelings or even cause air quantity shakiness during personal injury, door opening
The defect such as fixed, is that mine creates great safety benefit.
Brief description of the drawings
Fig. 1 represents return airway air door structure schematic diagram before transformation.
Fig. 2 represents return airway air door structure schematic diagram after transformation.
In figure, 1- the first air door partition walls, 2- the second air door partition walls, the air door partition walls of 3- the 3rd, 4- pedestrian's runway air door, 5-
Air channel window, 6- stoppings.
Specific embodiment
Specific embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.
A kind of underground coal mine binary channels high-low pressure air door ventilating system, as shown in Fig. 2 including first in return airway
The air door partition wall 2 of air door partition wall 1 and second, correspondence offers the and of pedestrian's runway air door 4 on the first and second air door partition wall 1,2
Air channel window 5.
As shown in Fig. 2 build the 3rd air door partition wall 3 by laying bricks or stones between the first air door partition wall 1 and the second air door partition wall 2, it is described
Correspondence offers pedestrian's runway air door 4 and air channel window 5 on 3rd air door partition wall 3.
As shown in Fig. 2 by building stopping 6 by laying bricks or stones by pedestrian between the first air door partition wall 1 and the 3rd air door partition wall 3
Runway and air channel separate；Similarly, will by building stopping 6 by laying bricks or stones between the air door partition wall 3 of the second air door partition wall 2 and the 3rd
Pedestrian's runway and air channel separate.
During specific implementation, the air channel width is the 1/3 ~ 1/2 of pedestrian's curb-to-curb width.
The 3rd air door partition wall 3 is equal with the distance of the first air door partition wall 1 and the second air door partition wall 2.
The current mine north and south big lane damper of both wings return air has been transformed successfully, eliminates pedestrian's traffic safety hidden danger,
With extensive popularizing application prospect.By the improved binary channels high-low pressure air door of mining company, pedestrian's row is substantially increased
Car safety, reduces regular maintenance, and personnel guard, can be 100,000 yuan of mining company's direct saving.
Finally it should be noted that above example is only used to illustrate the technical solution of the utility model and unrestricted, although
It has been described in detail with reference to the utility model embodiment, it will be understood by those within the art that, to the utility model
Technical scheme modify or equivalent, without departure from the spirit and scope of the technical solution of the utility model, its is equal
In should covering claims of the present utility model.
