Although there are some of the coal mines exposed to the ground surface, most of the deposits are underground. The veins may be too deep to reach. In this case, underground tunnels are dug to extract coal. Mine workers and machines enter and exit the bed through these tunnels. The obtained coal is also delivered to the surface through these tunnels. Coal mines face various dangers. At the beginning of these dangers are floods. However, with the developed pumping system, it is ensured that the mines remain dry. Ceilings also need to be constantly supported against collapse. Coal dust generated during drilling causes various lung diseases. To prevent this, miners use masks while working.
In addition, these diseases are tried to be prevented by installing ventilation systems in mines. There is also the danger of fire and explosion in coal mines due to the methane gas produced during the cutting of coal layers. For this reason, there were frequent fires and explosions in the times when the mines were lit with candles, today the mines are illuminated with electric lamps. However, sparks from machines hitting rocks can be dangerous from time to time. Today, mechanization in mines is quite advanced, separate machines are used for cutting, extracting, separating and transporting coal, so that more coal can be extracted in a short time with fewer workers.
