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.
Is coal environmentally friendly?
No coal is not really environmentally friendly . There are a lot more disadvantages than advantages when it comes to coal.
What would happen if you used up all the coal on Earth?
There would be no more coal left to use.
Which produces more radioactivity in the atmosphere coal fire power plants or nuclear power plants?
Coal fired plants.
How frightening was it and is it down in a coal mine?
There are two types of coal mines: a slope mine and a vertical shaft mine. There is also surface mining, where rock is blasted and rock and earth are moved aside or trucked away as they expose coal veins.We'll focus on slope mines and vertical mines.Slope MinesA slope mine originally started out (early 1800s) as a hole dug into the hillside, typically where coal was already seen on the surface (example: banks of the Monongahela River). To access those slope mines, men simply crawled into the hole on their bellies or backs, continually digging forward and pulling out earth, stones, and coal. This would be similar to today's gem hunting in the western US mountain areas, where men and women lay on their backs or bellies to dig deeper under the rock face or under a boulder.Expansion of Slope MinesEventually, slope mines were enlarged so a man could walk semi-upright or be seated in a rail car to be taken deeper into the mine.... so the mine's roof was perhaps 4 feet high from the ground. Many West Virginia mines were slope mines originally.Vertical MinesVertical mines means men could access the mine via an elevator system. An elevator car would take a team down and bring the men back up. These deep mines typically need ventilation shafts to bring air in, and for emergency escape IF assisted from the surface. For example, "The Quecreek Mine rescue took place in Somerset County, Pennsylvania, when nine miners were trapped underground for over 77 hours, from July 24 to 28, 2002. All nine miners were rescued." This was accomplished through a newly bored rescue hole, similar to a wide air vent bore hole.Vertical mines by the late 1800s included a surface tipple and a coal conveyor system from within the mine to the surface, along with an elevator-cage system. Today's coal mines are pretty much the same, except much larger and more mechanized; men either walk in, eventually stooped over, or ride in cars on rails; or use elevator-cages.HAZARDS OF MINESFirst, the environment inside a mine is typically warm and humid.Pockets of methane gas are a constant danger; methane is colorless and can catch fire/explode with a mere spark of one rock hitting another rock; from static electricity; from any source of fire or spark; from malfunction in machinery. Methane explosions and "toxic air" were leading causes of death in the 1800s.Flooding is a constant threat from underground water sources AND from a breach through the active mine's wall through to an abandoned but flooded mine.There are thousands of old, abandoned underground mines of various sizes and deteriorated conditions that were NEVER marked on any maps! It is therefore easy to be boring in one mine's wall and have a breach into an old mine's chamber.Old abandoned mine chambers can be full of methane, or flooded.Mines leave pillars of coal as the "studs" to hold up the roof of the mine. When a mine is played out (does not have enough coal to safely mine) or when the mine is deemed unsafe, these pillars can be deliberately blasted as a way to collapse the mine back to the entrance, so no one unauthorized can enter. But, coal pillars can also weaken on their own, causing a catastrophic collapse within the mine.In all mines, the "roof" or "ceiling", which can have miles of weight pressing down on it from the surface downward, is at once the most critical mine location, and the most destructive, fragile area. Roof collapse is deadly. A slate fall or coal fall from the roof can injure, crush, bury, or trap miners within the chamber they are in. Roof collapses were a common cause of injury, death, and being trapped in the 1800s.Mechanical failures that directly result in injury or death are less common than one might think. In the 1800s, men went into mines with helmets with a candle or lantern attached, and often took a canary--if the bird died, the miners knew to get out because the air was bad. Today, Mine Safety is much more sophisticated.ALL of these issues CAN still occur today. One of the worst mine disasters happened at the Marianna Mine, Marianna PA in Washington County, PA (SW PA). "At 10:55 a.m. on the morning of Saturday, November 28, 1908, an explosion occurred in the mine which killed 154 men and left only one survivor. Although the mine was quickly refurbished by the Pittsburg Buffalo Company, the colliery's fortunes flagged. By 1914, the mine was sold to the Union Coal and Coke Company and later to Bethlehem Steel which continued to extract coal until 1988, when the main conveyor caught fire. The fire was extinguished, but the mine closed anyway." (Wikipedia) Many of the men could not be reached and are entombed there.Many coal mines became tombs throughout the 1800s. Many mines had roof/slate falls that killed one or more miners. Many NE US miners came as immigrants to work in the coal mines. In the bituminous mines, especially, there were many debates/fights over miner qualifications (the "practical miner") and the beginning of Mine Safety measures began in the late 1800s. The United Mine Workers UMW union was also started in SW PA in the early 1900s.TO BE A MINER YOU MUST BE ABLE TOWork in confined spacesTolerate claustrophobic conditions of tight space, total darkness if lights go out, and constant dangerLearn safe mining practicesFollow safe mining procedures to the letterNever let down your guard or become complacentAlways protect fellow minersAppropriately use your mining gear and keep it in working orderKnow First-Aid and emergency medical equipmentKnow and Understand your escape routesFollow all directions superiors giveTolerate being blackened from coal dust, from head to footTolerate keeping your hardhat on at all timesEat while underground, without worrying about washing up firstBe willing to learn from oldtimers every dayBe willing to do long shiftsBe willing to come back and do your next assigned shiftThis is what millions of coal miners have done since the late 1700s. Millions of men did this job to supply coal and coke to steel factories, coal to railroads to power train engines, and to burn for heating homes and businesses. Men (and even women now) take huge risks to continue going underground for this resource.Poor families also used to send children to coal refuse waste piles of earth that had bits of coal embedded in clay, to chisel coal from the rock/clay to use in families' homes. Poor and homeless often built fires in coal refuse mounds to stay warm in winters. Coal refuse would catch fire also, from internal combustion due to the build-up of heat inside the mound of coal refuse. Many small towns had refuse pits that burned for years. (Burning coal refuse--the unusable coal-- creates red dog, which was used on many rural roads before they made asphalt.)One town's coal mine caught fire and is still burning under Centralia, PA which started in the 1960s, and eventually forced the US Government to relocate its residents.
What is a tongue twister about Maine?
In Maine, a man made many mini mementos.
Can coal be renewed and be brought about again?
it is found in coal mines and then they find 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
Why should people use more or less of coal?
People should use less of coal because coal mines have dangerous gases sulfur oxide and methane that causes mines to explode and the gases that can also poison humans. Plus burning coal can cause a disease that causes animals to swell up to 5 times their normal size.
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 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!
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.
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.
