In the old days, miners took canaries with them to the slaughter. This practice may seem strange these days, but it was not a superstition, but a great way to check the methane level in a mine. These birds were very sensitive to this gas, if the canary is silent for a long time, it is necessary to urgently evacuate.
In 1815, the English scientist Humphrey Davy invented a safety lamp for miners. A large number of miners died from methane explosions, therefore, using open fire in the mine was life-threatening. And the miners had to use tallow candles, which gave little light, but often caused tragedies. The principle of operation of the Davy lamp was that the flame was cooled by passing through a metal mesh. Thus, the temperature outside the lamp was lower than that at which methane ignited.
According to some reports, the real name of the famous Soviet miner Stakhanov is not Alexei, but Andrei. The confusion resulted from a journalistic oversight. In 1935, Stakhanov, together with two woodworkers, exceeded the daily rate of coal production by 14.5 times. By the way, the mass movement of the foremost workers in the USSR after this record was called "Stakhanovskoe". At the solemn meeting, the journalist did not hear the name of the hero of labor, and called him in his article Alexei. And this article was published not just anywhere, but in the newspaper Pravda. And she, as you know, at that time could not be wrong. So they decided - it's better to be Alexei Stakhanov than to write a refutation. By the way, the miner's relatives claimed that these were just rumors.
Until the middle of the twentieth century, there was a position in the mines with the unusual name "tabakotrus". He had to strictly monitor that the miners did not bring matches and tobacco products into the mine. After all, smoking underground could end sadly. Responsibility for violation of this instruction was strict: deprivation of the premium, at least. And in some cases, the case could go to court.
The deepest mine in the world is located in South Africa. The depth of the Tau-Tona mine is about 4.5 km. The largest reserves of gold in the world are concentrated here. The temperature in the face exceeds 50 degrees, therefore, it is necessary to use powerful cooling systems. A high-speed elevator delivers the miners to the workplace. Interestingly, in South Africa, about half of all gold in the world was mined.
There is a sign - if you forgot something at home, then you can return, you just need to look at your reflection in the mirror. For a miner, this is unacceptable: to return is unfortunately. Even if the miner has forgotten the thermos with lunch, he would rather work the shift hungry than go for it.
In 1935, the International Labor Organization outlawed the use of women miners, unless otherwise specified. But, during the Great Patriotic War, most of the miners in the Soviet Union were women who had to replace the men who went to the front. Six miners were even awarded the title of Hero of Socialist Labor.
In 1874, an underground fire occurred in Liuhuanggou, a coal deposit in China. The fire could not be extinguished for 130 years - until 2004. During this time, the fire destroyed about 260 million tons of coal.
