Description
Technical Field
The utility model relates to a mining obturator, especially a mining gasbag formula quick obturator.
Background
Mine fires are one of the main natural disasters in coal mines. Once a fire accident occurs in the mine, the production is affected slightly, and all underground production equipment can be burnt and the production of the mine can be stopped seriously, so that huge economic loss is brought. In the disaster relief process, cases of secondary accidents caused by untimely sealing and poor sealing effect are not enumerated. How to realize the fast and high-efficient fire area sealing in the mine disaster relief process is the main technical problem of shortening the duration time of the fire, reducing the accident loss and avoiding the secondary disaster.
The existing early wood board widely applied on site is coated with yellow mud, or the temporary sealing of the rapid foaming material sprayed by a sand bag wall and a wood board wall is adopted in recent years, although the wood board has the characteristic of simple structure, the required material consumption is large because the installation position is changed along with the difference of ignition places, so that the transportation of the wood board, the wood column, the sand bag, the yellow mud and other materials is very difficult, the problems of time consumption and labor consumption are serious, the sealing effect after the installation is poor, the fire area cannot be rapidly and efficiently sealed, the fire area is unfavorable for rescue work in disaster areas, and the life safety of constructors cannot be guaranteed.
Since the patent number ZL97200747.4, the invention name is 'air bag for rapidly sealing a fire area under a mine' successfully researched and developed, the rapidly sealing air bag is widely applied to the underground of the coal mine. The quick closed air bag gains market acceptance due to good elasticity and toughness, light weight, short inflation time, convenient installation and use, repeated use, good economy and the like; however, in practical application, the annular single airbag has a good sealing effect in an arch-shaped roadway, but in the environment of the roadway with rectangular, trapezoidal and irregular inner walls, gaps are left at two top shoulder parts and irregular inner wall parts of the roadway, so that the sealing effect is greatly influenced; in addition, after the underground fire area is blocked by the quick closed air bag, after the fire area is effectively controlled, rescue workers cannot enter the disaster area to observe the fire condition under the condition of ensuring safety, and inconvenience is brought to quick closed unsealing and subsequent rescue and production recovery work.

The implementation method of the mining air bag type quick closing device comprises the following steps:
step one, arrangement work
When a fire disaster occurs in a mine, rescuers quickly send the air bag type quick sealing device to a sealing position, select a place where a roadway support and a roof are complete without pumping as much as possible for construction, properly clean sundries in the sealing place, find the central position of the support during construction, firstly hang the hook of the air tent on the support, and then hang the rope buckle of the air bag on the hook of the air tent 3.
Step two, inflation work
Firstly, combining an underground compressed air pipe with an air charging nozzle, and slowly charging air into an air bag; the main airbag 1 is inflated a little and is not inflated to a saturated state; the position state of the air bag is adjusted, and the air bag is preliminarily attached to the roadway; when the air bag, the wind curtain 3 and the inner side of the roadway are completely attached, secondary inflation is carried out, and the state of the air bag is adjusted in time to be tightly sealed; at the moment, the air is slowly inflated to a working state; the inflation speed is not too fast, the inflation can be closed when the air bag slowly becomes rigid, and the protective cap of the inflation nozzle is screwed down. In rectangular, trapezoidal and irregular roadways, the ballonet 2 also needs to be inflated. The inflation can be carried out by using an underground compressed air system, a high-pressure nitrogen cylinder can be matched with a pressure reducing valve for inflation, and a pedal inflator pump can be used for manual auxiliary inflation.
Step three, gas sample collection work
In the closed period, in order to facilitate real-time monitoring of parameters such as air temperature, gas concentration, oxygen concentration and the like in the closed interior, the harmful gas sampler can be used for observing and collecting information about toxic and harmful gases in the disaster area, the components and the concentration of the toxic and harmful gases are analyzed, first-hand data are obtained for unsealing the disaster area, and the safety of rescue workers is guaranteed.
Step four, the rescue workers enter the closed disaster area to observe the disaster situation
After the rescue personnel obtain the harmful gas in the disaster area, the rescue personnel can cross the air door 5 to enter the disaster area to observe the fire under the condition of ensuring the safety of the personnel, and can carry out subsequent work such as effective further rescue.
Step five, recovery work
After the sealing is finished, the fire area is unsealed, the inflating nozzles of the main airbag 1 and the auxiliary airbag 2 are opened, the exhaust work is finished, and then the airbags and the wind curtain 3 are detached, folded and bagged. The device can be reused.
The quick airtight air bag device is simple in structure, convenient to use, good in plugging effect, easy to install and recycle, reusable, simple in operation of an airtight method, quick in airtight channel, capable of quickly and efficiently blocking disaster propagation and avoiding damage of disaster accidents to people, machines and environments.
