Open cut hazards are principally mine wall failures and vehicle collisions; underground mining hazards include suffocation, gas poisoning, roof collapse, rock burst, outbursts, and gas explosions. Firedamp explosions can trigger the much-more-dangerous coal dust explosions, which can engulf an entire pit.
Why are coal mines so dangerous?
Working in coal mines is dangerous — miners have to deal with toxic gases, plus the threat of being crushed, drowned, or injured from fires and explosions.
Why was coal mining so dangerous in the 1800s?

How dangerous is underground coal mining?
Fire, flood, collapse, toxic atmospheric contaminants, and dust or gas explosion are the most critical hazards specifically linked to underground mining.

How deep do coal miners 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).
How many hours did coal miners work?
Many families worked for up to 12 hours each day, and for 6 days a week. The only days off would be Sundays and holy-days like Christmas or Easter. Some mine owners might have given their workers a day off on the day of Queen Victoria’s Coronation.

Which type of mining is most dangerous and why?
Statistically, coal mining remains more dangerous than other kinds of mining, but only slightly. According to the U.S. Mine Safety and Health Administration, the rate of coal-mining deaths in the United States between 2001 and 2005 was 0.15 per million production hours.18 мая 2010 г.
Does coal mining cause global warming?
Climate change is coal’s most serious, long-term, global impact. Chemically, coal is mostly carbon, which, when burned, reacts with oxygen in the air to produce carbon dioxide, a heat-trapping gas. When released into the atmosphere, carbon dioxide works like a blanket, warming the earth above normal limits.
Why we should stop using coal?

How much does coal contribute to global warming?
Coal is the single biggest contributor to anthropogenic climate change. The burning of coal is responsible for 46% of carbon dioxide emissions worldwide and accounts for 72% of total greenhouse gas (GHG) emissions from the electricity sector.
