How is coal mining done today?
Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. … Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal.
What is a coal miners job?
Coal miners extract coal from surface mines and underground mines. To do this, they operate complex and expensive machinery that drills, cuts, scrapes, or shovels earth and coal so that the fuel can be collected.
What chemicals are used in coal mining?
Chemicals accounted for about 13%, and coal/petro leum products, including processed coal, clinkers, meth ane gas and solvents, creosote, hot oil, hydraulic fluid, antifreeze, gasoline and mouse milk accounted for about 8%.
Do coal miners get paid well?
The average starting salary for a coal mine worker is $60,000. “You can come right out of high school and make $70,000 a year,” said Missy Perdue, 22, a stay-at-home mother whose husband, Jeff Perdue, Jr., 22, is a miner.
What is the life expectancy of a coal miner?
The average life expectancy in the coal mines for those starting work at 15 y was found to be 58.91 y and 49.23 y for surface and underground workers respectively. In the coloured/metal mines they were 60.24 y and 56.55 y respectively.
Is Coal still being formed?
The process of coal formation is still taking place today, says Bailey. “The precursor to coal is called peat, and that is just uncompressed plant matter.” Peat accumulates in wet swampy environments known as mires, and that process is taking place today in areas such as Indonesia and even the Antiplano in the Andes.
Is coal mining still dangerous?
Coal mining is still dangerous. In 2010, West Virginia had the worst coal mining disaster in the US in 40 years, when an explosion killed 29 people. … That year, 3,242 people died in coal mining accidents. Coal mines have continued to have fires and explosions, killing hundreds of miners over the years.
How deep do coal mines go?
Coal that occurs at depths of 55 to 90 m (180 to 300 ft) are usually deep mined, but in some cases surface mining techniques can be used. For example, some western U.S. coal that occur at depths in excess of 60 m (200 ft) are mined by the open pit methods, due to thickness of the seam 20–25 metres (60–90 feet).
Why is coal mining bad?
Along with adding to greenhouse gas pollution, burning coal emits toxic and carcinogenic substances into our air, water and land, severely affecting the health of miners, workers and surrounding communities.

What toxic substances are produced from mining?
1 Some toxic metals frequently associated with mining include mercury, arsenic and lead. These substances are present at low concentrations in soil, rock and water, but the process of mining may release quantities harmful to the health of people and the environment.
What is a common hazard posed by mining chemicals?
The principal airborne hazards in the mining industry include several types of particulates, naturally occurring gases, engine exhaust and some chemical vapours; the principal physical hazards are noise, segmental vibration, heat, changes in barometric pressure and ionizing radiation.
What chemicals are used in gold extraction?
A sodium cyanide solution is commonly used to leach gold from ore. There are two types of leaching: Heap leaching: In the open, cyanide solution is sprayed over huge heaps of crushed ore spread atop giant collection pads. The cyanide dissolves the gold from the ore into the solution as it trickles through the heap.
