we dont say a fix depth of underground mine becoz that is depends on geological conditions of the area where we mined and also depends the property of mineral which have to be mined. Companies engaged in this industry extract coal that lies 200 to 1,000 feet below the earth's surface, though some mines are as deep as 2,000 feet.

How many miles deep are coal mines?
Coal mines can range in depth from a few hundred feet to over a mile deep, depending on the location and mining method used. Underground coal mines are typically deeper than surface mines due to the nature of the coal deposits.
Why coal mines are deep?
Coal mines are deep because coal deposits are generally found deep underground, requiring extensive excavation to reach and extract. Deeper mines also provide access to more extensive coal reserves, allowing for long-term extraction. Additionally, deeper mines often have higher-quality coal deposits compared to shallower ones.
Why are coal mines deep inside the earth?
Coal mines are usually deep inside the earth because coal deposits form over millions of years in layers of sediment. These layers are then buried deep underground by geological processes, making it necessary to dig deep to access the coal. Additionally, mining deeper coal seams can result in higher yields and better quality coal.
Who is the person who extract coal from the ground?
A coal miner is the individual who extracts coal from the ground. They work in underground mines or surface mines to extract coal for energy production and other industrial uses.
How coal is removed from deep under the ground?
Coal is removed from deep underground through a process called underground mining. This involves digging shafts into the ground, then using machinery to extract the coal from the coal seam. Miners then transport the coal to the surface for processing and distribution.

How deep were Victorian coal mines?
Victorian coal mines could extend to depths of several hundred feet underground, depending on the specific location and vein of coal being mined. Some mines reached depths of over 1,000 feet. Workers often faced dangerous conditions due to collapses, flooding, and poor ventilation.
What state has the most underground mines?
West Virginia leads the nation in underground coal mining with 193 underground mines that produced 99.6 million metric short tons in 2001.
When the 1842 Coal Mines Act forbade the underground employment of who?
The 1842 Coal Mines Act forbade the underground employment of women and girls in coal mines in Britain. This was in response to growing concerns about the harsh working conditions and exploitation experienced by women and children in the mines.
