Question: Is underground coal mining dangerous?

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.

Is coal mining the most dangerous job?

Coal mining has gotten safer over the past 30 years, according to United Mine Workers spokesman Phil Smith, but much of the reduction in fatal accidents is because production has shifted above ground to strip and mountain-top-removal mining. Coal is inherently more dangerous than metal mining, said Smith.

What are the pros of underground mining?

Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining is the preferred method for mining gold, silver, and uranium.

Is surface or subsurface mining worse?

Subsurface mining is actually less disruptive to the earth and produces less waste than surface mining, but it’s also much less effective and more dangerous. Many workers die in mine collapses, which then also leaves behind a large hole from caving in of the ground above.
