Coal mines have continued to have fires and explosions, killing hundreds of miners over the years.

Can you find gold in coal?

Gold occurs as palaeoplacers and in hydrothermal deposits. Gold occurrences reflect rapid erosion of the mineralized orogeny and young provenance of sediment in the coal basins. The disposition of the Variscan Orogen through equatorial latitudes made coal an exceptional reservoir for gold.

How long does a coal mine last?

Based on U.S. coal production in 2019, of about 0.706 billion short tons, the recoverable coal reserves would last about 357 years, and recoverable reserves at producing mines would last about 20 years. The actual number of years that those reserves will last depends on changes in production and reserves estimates.
