Coal Mining Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
The conversion of aging coal plants to run on natural gas is increasingly considered a viable way for energy producers to reduce emissions and cut costs.
The Deserado coal mine just outside Rangely employs 178 workers and produces about 1.5 million tons of coal a year for Deseret Power's Bonanza plant.

U.S. power plants received 449 million short tons (MMst) of coal in 2021, less than half of the 957 MMst they received in 2010. Coal shipments to U.S. power plants declined over the past decade as coal-fired generation in the country fell and coal-fired power plants shut down.. Although coal shipments have been trending down over the …
Second, coal power plants are long-lived assets with a minimum design lifespan of 30 to 40 years. Once built, coal plants are here to stay unless there are dramatic changes in the costs of renewables or policy makers intervene. Third, moving away from coal typically means losses for the domestic mining industry and its workers.
Coal gasification is a century-old technology, but in recent years the coal industry has revived it as an alternative to natural gas and petroleum as part of efforts to rebrand coal as a carbon-neutral energy source. While most efforts to build coal-to-gas plants in the US have failed, the technology is widely used in China and South Africa – …
US coal power plants emitted more than 3.1 million tons of SO 2 in 2014. Nitrogen oxides (NOx): Nitrous oxides are visible as smog and irritate lung tissue, exacerbate asthma, and make people more …

Prices have fluctuated since then, but gas has continued to be plentiful and cheap. This has had two effects on coal. One is that cheap gas displaces coal in existing power systems. Secondly, cheap gas increases the incentives to finally retire old coal-fired plants from the 1940s and 1950s.
