Description
Technical field
The present invention relates to a kind of mine working air door relief valve and its working methods.
Background technique
During mining production, since underground is opened up, ore extraction needs, and explosion becomes important in mining production
Construction means, its main feature is that efficiently, low cost.However adjoint safety problem also comes one after another.One of them are explosions
The detonation gas and toxic fumes of generation.The pressure that wherein detonation gas was generated in moment is to the supporting in tunnel, the tool such as equipment
During having damaging, such as coal production, coal-dust explosion makes quick-fried source, and nearby gas temperature rises suddenly, to make the pressure of gas
Power increases suddenly, and the theoretical pressure of coal-dust explosion is 0.736MPa, but when there is a large amount of dust accumulation tunnels, blast pressure will with away from
The increase of quick-fried source distance is then in jumpily to increase.In general, the footrill access adit away from quick-fried source 200m, blast pressure up to 0.5 ~
1.0MPa.If be obstructed in the channel of shock motion, blast pressure will also rise.Shock velocity is up to 2340m/s.
Such high pressure, shock wave can cause human body viscera greatly to damage, and the personnel of shifting onto cause wound and internal injury, ruin bracket and cause lane
Road, which collapses, to be emitted, and is damaged mine ventilation facility and is caused disorder, destroys electromechanical equipment and mine car causes production disruption, is blown and is raised dust accumulation and cause coal
Dirt explodes again.If cannot timely pressure release, will be very big security risk.Secondly, toxic fumes are also required to be discharged in time, otherwise
The life security of construction personnel is impacted, carry out subsequent construction progress can not, influence mining production.And relief valve is made
For a kind of effective pressure release mode, when tunnel, cave room pressure increase, can be open rapidly pressure release and is discharged toxic gas;To
Gas pressure is reduced to a certain degree constantly, can be resetted rapidly.For ensureing Mine Safety in Production, efficiently production has important work
With.
Summary of the invention
In view of this, being able to achieve the object of the present invention is to provide a kind of mine working air door relief valve and its working method
