Road, isobaric fire dam, isobaric tunnel, flame proof fire dam, sandbag fire dam, the steel plate fire dam, gas for absorbing detonation wave energy
Library tunnel, which is sequentially connected, to be connect.There are the semi-circular tunnel for making detonation wave shunt pressure release in gas library tunnel two sides, and both ends connect gas
Library tunnel.The detonation wave that gas library tunnel connects straight-through ground shunts pit shaft, has a pit shaft cover board on ground, in the tunnel of gas library
Gas pressure when increasing suddenly pit shaft cover board open automatically.
Implement the present invention, needs personnel to can enter gas library tunnel and check.Therefore, isobaric fire dam, flame proof fire dam,
There are the people's row air door of flame proof often closed, sandbag fire dam someone walking corridor on steel plate fire dam.
Implement the present invention, there is a pump-line along gas library tunnel overall length, the sensible mine ventilation roadway of the pipeline and along mine
The sensible ground in well airway and the aspiration pump for connecting ground, aspiration pump are separately connected ground transition gas library and atmosphere.Have out
For gas tube orifice close to the gas injecting pipe of steel plate fire dam, the pipeline is along the sensible ground of mine ventilation roadway and is separately connected ground transition
Gas library and atmosphere.
It is interior to be full of air when gas library tunnel starts to store gas, open ground aspiration pump and its connection surface air
Pipeline valve, the air in the tunnel of gas library, which is extracted, is discharged into surface air.At the same time, it opens gas injecting pipe and connects ground
The pipeline in transition gas library, the gas in transition gas library inject gas library tunnel from the gas library tunnel other end.Keep pumping
Flow in pipeline and gas injecting pipe is equal, makes that the gas volume in the tunnel of gas library is constant, air pressure is constant.In this way, gas is set
Change the air in the tunnel of gas library.
Implement the present invention, when utilizing tunnel gas library Neva at this moment, opens ground aspiration pump and its connection ground transition watt
The pipeline valve in this library, by the gas in the gas library of tunnel, from gas library tunnel end, extraction is discharged into ground transition gas library.With
This opens gas injecting pipe on ground and connects open to atmosphere pipeline, ground air injects gas library from the gas library tunnel other end simultaneously
Tunnel.The gas flow adjusted in pump-line and gas injecting pipe is allowed to equal, and the gas volume in holding gas library tunnel is not
Change, air pressure are constant.
Implement the present invention, the gas exchanges of air in gas and the mine ventilation roadway in the tunnel of gas library need to be prevented and treated.For
This, has equal pressure pipelines to be laid with along mine ventilation roadway, connects isobaric tunnel and ground.In isobaric tunnel and in mine ventilation roadway
There are the equipment of monitoring air pressure and the facility of information wireless transmission.During gas library tunnel starts to store gas and be full of gas,
The pipeline valve in equal pressure pipelines connection ground transition gas library is opened, and injects gas to isobaric tunnel, keeps isobaric tunnel inner body
Product is constant, air pressure is constant, air pressure is equal with the air pressure of mine ventilation roadway.It is isobaric during extracting gas out in the tunnel of gas library
Pipeline connects open to atmosphere pipeline valve on ground and opens.
Implement the present invention, the low-lying water accumulation part in gas library tunnel has sump.There are immersible pump, the draining of immersible pump connection in sump
Pipe and the sensible mine ventilation roadway of cable.Drainpipe is connected reserve pump in mine ventilation roadway.
Advantages of the present invention is to eliminate the problem that the land occupation of ground gas library is more, prestige helps ground safety.
