The coal seam fires that have been burning for 300 years, why not put them out directly with water?

Naturally, the Helan Mountain coal seam cannot be extinguished directly with water, otherwise a rainstorm can stop it, and it is impossible to continue burning for more than 300 years, and it has never been extinguished.

Because the coal seam may be burned with water to produce carbon monoxide, this gas is easy to mix with air at high temperatures, and the entire coal seam will be blown up, so it cannot be extinguished with water.

Because the 300-year-old coal seam fire was large, and if it was used water, it would accelerate the burning, so it was extinguished without water.

There will be a chemical reaction, which is the same as the combustion of oil, and pouring water will only become more and more vigorous.

We all know that the main element of coal is carbon, which will be oxidized in the air and will undergo a chemical reaction when water is poured on itThis results in the production of carbon monoxide, so that the fire burns more and more vigorously, not only that, but serious may occur**.

Spontaneous combustion of coal seam is a very complex chemical reaction process, and its spontaneous combustion is the result of long-term contact with air, because the oxygen content in the air is relatively high. Spontaneous combustion can easily occur over time, and the only way people think of extinguishing a fire is watering. But since it reacts chemically with water, the product is carbon monoxide.

We all know thatCarbon monoxide is a dangerous substanceIn order to avoid such a phenomenon, then what should we do?

First of all, when encountering the phenomenon of spontaneous combustion of coal seams, don't be nervous or panicked, and worry about it. Be sure to deal with it calmly and never try to douse it with water. In case of emergency, it should be dredged first, and if it is not large, emergency measures should be taken.

Be sure to keep crowds away from spontaneous combustion areas. In general, the amount of coal seam in the area is not very large, because this step is not so necessary.

Secondly, if the fire is not large, it can be extinguished with chemicals such as fire extinguishers. If the fire is large, it is recommended to leave the spontaneous combustion area immediately, and after confirming your own safety, call the fire alarm ** to indicate the situation, and be sure to explain that the fire phenomenon is caused by the spontaneous combustion of the coal seam.

Finally, wait for rescue. If the fire is too strong, stay away from him and evacuate the crowd.

In short, do not try to extinguish a coal seam fire with water.

Because coal seam fires are burned by oxygen, water does not isolate oxygen.

Because you don't know how big the coal fire is, if the whole mountain, several kilometers of coal seams are on fire, where are you going to get so much water to extinguish it? You might say that it rains, and if you've used honeycomb coal, burning honeycomb coal, you splash a few drops of water, and it will only produce water gas. The real drop in the bucket, this is a glass of water and a mountain of salary.

This is because when the water evaporates, oxygen is produced, and then it can be burned again.

Because of the coal seam fire, there is still a layer of material on it, and it is not completely simple life.

It may be because the coal seam fire water cannot isolate oxygen and cannot be burned.
