It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity.
Why are coal mining important?
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
Why was coal mining dangerous?
Working in coal mines is dangerous — miners have to deal with toxic gases, plus the threat of being crushed, drowned, or injured from fires and explosions.
Why should we stop coal mining?

Does coal have a future?
The current administration favors coal, but that policy may not continue in future administrations. Displacing coal-fired power generation is a very cost-effective way to reduce U.S. energy-related greenhouse gas emissions, and thus could be targeted by a future administration more concerned about climate.
Is Coal good for environment?
Coal provides many jobs. Unlike other forms of energy (nuclear, natural gas, oil, hydroelectric), coal provides many jobs in removing coal from the earth, transporting it to the utility, burning it, and properly disposing of coal ash. … Coal can be mined and burned with little environmental impact.
