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 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.
What are the disadvantages of underground mining?

Do all coal miners get black lung?
Black lung disease has been identified in coal miners in every coal-mining state at both surface and underground mines.
What diseases do coal miners get?
The two main types of pneumoconioses that affect miners are coal workers’ pneumoconiosis (CWP), commonly called black lung, and silicosis. CWP is associated with coal mining, but silicosis can affect workers in many types of mines and quarries, including coal mines.
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.
What is the deepest type of underground mining?
The deepest mines in the world are the Mponeng and TauTona (Western Deep Levels) gold mines in the Witwatersrand region of South Africa, which are currently working at depths exceeding 3,900 m (12,800 ft).
