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.
How deep did the coal miners have to dig to get the coal?
Depths of coal seams vary from place to place. The first coal mine in the US was in Midlothian VA, near Richmond. Coal was present on the surface- just pick it up. Later mines in that area were about 360 ft deep. Other mines are deeper- but much coal is still mined from the surface in high wall or long wall mining.
What are the advantages and disadvantages of coal mining?
Coal mining has many very bad cons and drawbacks. For one, it is highly dangerous. Coal mines have been known to collapse in on workers, trapping or killing them. The dust and dirt and materials in the mines and air around the mines can be polluting and can be very harmful when breathed in or on the skin, especially for longer periods of time. Coal is a finite resource. It take millions of years to replenish itself. With the limited amounts constantly being mined and used for energy, the resources of coal around the world are depleting. If mining continues, eventually there will be pretty much no more coal left. The effects of burning and using the mined coal for energy also cause pollution and are bad for the environment.
Why is there a danger of explosions in places such as silos and coal mines where there are large quantities of powdered combustible materials?
- because the large quantities of the powdered and combustible materials incluse two factors of increasing the reaction rate, which are more surface areas and high concentration. - And also in such these places the tempreture is high more often, so it will lead to more collision between particles and speeding up the reaction rate as well. - And the final reaction will be as an exothermic, so the energy will be released in the form of eplosion and flames.
Can coal be reused?
Coal can be reused through a process called coal recycling or coal reprocessing. This involves converting used coal into a more refined form that can be used again for various purposes, such as in power generation or industrial processes. Recycling coal can help reduce waste and environmental impact associated with coal mining and combustion.
What is a tongue twister about Maine?
Maine has mines mimes mops and more.

In which region would you find more coal mines the southwest or southeast?
You would find more coal mines in the Southeast region of the United States, particularly in states like West Virginia, Kentucky, and Pennsylvania. These states are known for their abundant coal reserves and long history of coal mining.
Does the southeast region have more coal mines than the southeast?
Yes, the Appalachian region in the southeastern United States has historically had more coal mines compared to the southeastern region. This is because the Appalachian region is known for its abundant coal reserves and has a long history of coal mining.
In which region would you find more coal mines the south west or south east?
southwes
How new sources if energy specifically coal contributed to industrial revolution?
Burning coal allowed the steam engine to pump water out of the mines. This allowed miners to dig deeper into the ground. Coal was a more efficient source of energy than wood, because it lasted longer. This discovery created more jobs in the mines because there was suddenly a higher demand for it.
Why is coal mining a difficult task?
coal mining can be a dangerous job, thousands of miners have been killed or injured in accidents in the mines, many more suffer from " black lung".
Why most industries are concentrated around coal mines?
Most Industries are concentrated around coal mines or the following reasons- 1. We know that the major industries are iron and steel industry. 2.The iron and steel industry requires heat to melt the steel to form different shapes. 3.Therefore more heat can be generated by the energy stored in the coals. 4.This energy can be easily available as coal mines are nearly located.
Can coal be renewed and be brought about again?
No, coal is a non-renewable resource. It takes millions of years for coal to form from dead plant matter, so it cannot be replenished within a human lifespan. Once it is extracted and burned, it is gone.
What did the woman do in the coal mines?
she was there to sort the blokes out after work the idea was to keep people in the mines longer to get more work done.however this idea back fired and the workers could not work as they had vietmenesse jungle dick rot

What are 2 methods used to mine coal out of the ground to make electricity?
The two typical types of coal mines are tunnel mines, where the coal vein is dug out by tunneling into it, or "Open Pit" mines, where the coal and surrounding rock are dug out in a large pit and separated. The type of mine used is often determined by the hardness of the surrounding rock, hard rock is often avoided and the coal tunneled out of it. Soft rock or soil is more safely and easily handled with open pit mining. This often produces low grade waste known as "culm" which is poor quality carbon deposits.
