Underground Coal Mining

Underground coal mining has a fatality rate of 15–25 per 100,000 in developed nations — but in China and parts of South Asia it can run 10x higher in poorly regulated operations. Beyond catastrophic methane explosions and roof collapses, miners face black lung disease (coal workers' pneumoconiosis), spontaneous combustion events, flooding, and confined-space entrapment. China's coal sector has historically produced over 1,000 fatalities per year even as safety reforms reduced the rate from over 6,000 annual deaths in the early 2000s.
