Coal mining traditionally took place underground, with men and equipment following seams of coal deep within mountains. Since the 1960s, surface mining methods have become more common, and today they account for more than half of the coal produced in the United States. In this approach, also known as strip mining, oversized bulldozers remove the land surface until coal
Coal Types, Formation and Methods of Mining - epcamr.org
Surface mining is accomplished by removing overburden from the coal seam and then blasting and removing the coal. The ratio of overburden excavated to the amount of coal removed is called the overburden ratio. The lower the ratio, the more productive the mine. The lowest overburden ratios are found in western surface mines.
