Description

technical field [0001] The invention relates to an automatic gas discharge control device for mine explosion-proof coal bunkers, which belongs to the technical field of gas discharge from coal bunkers. Background technique [0002] Generally, due to the strong adhesion of gas to coal, when coal is transported from underground to underground coal bunkers or ground coal bunkers, a large amount of gas will be brought into the coal bunker. After the gas is separated from the coal, it is easy to accumulate in the coal bunker , cause the gas to exceed the limit, and when the concentration is too high, it will cause suffocation or even death, and may cause a gas explosion, which will bring safety hazards to the safe production of the mine and cause serious economic losses. Therefore, gas disasters have become a threat to mine safety. , An important factor restricting the development of mines. [0003] In order to reduce the gas concentration in the coal bunker and solve the proble...

[0002] Generally, due to the strong adhesion of gas to coal, when coal is transported from underground to underground coal bunkers or ground coal bunkers, a large amount of gas will be brought into the coal bunker. After the gas is separated from the coal, it is easy to accumulate in the coal bunker , cause the gas to exceed the limit, and when the concentration is too high, it will cause suffocation or even death, and may cause a gas explosion, which will bring safety hazards to the safe production of the mine and cause serious economic losses. Therefore, gas disasters have become a threat to mine safety. , An important factor restricting the development of mines

[0003] In order to reduce the gas concentration in the coal bunker and solve the problem of gas disasters, the current traditional method is to reduce the gas concentration in the coal bunker through natural ventilation or forced ventilation. The gas concentration exceeds the standard, the gas emission effect is not ideal, and the safety is low; the forced ventilation method lacks the monitoring of the gas concentration gas and the adjustment and control of the air volume, and it is easy to waste resources if the ventilation equipment is turned on for a long time. The principles of noise reduction and emission reduction are contrary
