Why are there gas pockets in mines?
Gas pockets in mines are formed due to the release of gases from coal seams or surrounding rocks. These gases can include methane, carbon dioxide, and hydrogen sulfide, which can accumulate in pockets due to geological processes. In mines, if these gases are not properly ventilated, they can pose a serious safety risk to miners in the form of explosions or asphyxiation.
Why do coal mines explode?
Coal dust in the air is an explosive mixture, because the mixture of coal and air can burn much more rapidly than solid pieces of coal can (flour in the air is also explosive, or sawdust - any flammable substance in the form of dust becomes explosive if it is mixed into the air). The process of mining coal is messy, and creates a lot of dust. And any spark can set it off. No smoking in the coal mines!
Where do you find coal?
Coal is typically found in coal mines, which are located underground or in open-pit mines. Coal deposits are often concentrated in specific regions known for their coal reserves. Major coal-producing countries include China, the United States, India, Australia, and Indonesia.
How is coal stored?
Coal is stored in stockpiles or bunkers at coal-fired power plants or coal mines. These stockpiles are monitored for temperature and moisture levels to prevent spontaneous combustion. In underground coal mines, coal is stored in bins or silos.
What is the name of coal dust?
In a coal mine coal dust , mixed with oxygen and methane is known as 'fire damp'. Any flame or electric arc will ignite a flash explosion. Miners often breed canaries (finch type birds), and occasionally take then down the mine. This is because the bird is very susceptible to poisonous gases and fire damp. It is likely to fall off its perch if poisonous gases are present, whereupon the bird is quickly removed to cleaner air , where it recovers. Coal dust , coal particles are best kept under control by the use of a fine spray / mist. of water.
What is canaries in a coal mine?
At one time, canaries were carried into coal mines as an early warning system for the presence of poisonous gases. Since canaries are very small, they would die before humans could be affected.
Is earth made up of any poisonous gas?
Yes, Earth has several naturally occurring poisonous gases, such as carbon monoxide, hydrogen sulfide, and radon. These gases can be harmful to human health and the environment. They are often found in specific locations, such as volcanic areas, coal mines, or as byproducts of industrial processes. Proper ventilation and safety measures are essential to mitigate their risks.

Were coal mines safe during Industrial Revolution?
No, they were not. As mines got deeper the risks of roof collapses, poisonous gases, accidents and lung cancer became a very high risk. The pressure and weight of the earth and coal became heavier so they would sometimes cause the wooden beams supporting the tunnels collapse. The ventilation problem caused poisonous gases to enter the tunnels were men were working, it caused choke damp and suffocating. Also, some of the gases were highly explosive and even the smallest spark would cause them to explode. Accidents happened when miners banged there heads on the wooden beams and fell and got knocked down by falling rocks or by the trams. Lung disease was cause by inhaling the coal dust.
How did child labor improve in coal mines?
