The Average Salary of a Surface Coal Miner Career Trend

Some strip mining operations produce holes hundreds of feet deep that resemble canyons. Miners use bulldozers and explosives to strip away layer after layer of soil and rock. Once they reach a layer of coal, they remove it using extractors that grind the coal into small chunks, which can easily load onto trucks.
