Coal miners played an outsize role in the 2016 election. Along with manufacturing workers, coal miners came to broadly represent the plight of working-class white Americans, unfairly targeted by the administration of Barack Obama and buffeted by the vagaries of an unhelpful economy. Donald Trump even donned a hard hat at one rally in West Virginia, miming mining coal (with a shovel, for some reason).


But according to coal mining and extraction most recent national data from the Bureau of Labor Statistics, there were far fewer coal miners in the United Coal mining and extraction in May 2015 than many other job categories, coal mining and extraction. (That data was released at the end of March 2016; estimates for mid-2016 will be released at the end of this month.)

How much so? Here, see how well you do on this quiz, measuring the number of coal mining extraction workers against a number of other categories.

So how many coal miners are there? In the most recent jobs report, the mining industry accounted for 183,300 jobs. But that includes a lot of mining unrelated to coal and a lot of support occupations, too: supervisors, truck drivers and so on. In May 2015, there were 69,460 jobs in coal mining itself — only 15,900 of which were extraction workers or helpers, mining machine operators or earth drillers.

That’s 0.019 percent of the American workforce that month.

The frustrating reality is that the industry has a number of strikes against it: the exhaustion of easy-to-access coal seams, the new focus on the carbon dioxide released by burning fossil fuels, the low cost of natural gas thanks to fracking and increased automation. Coal miners are important parts of the economy and the cultural identity of certain states important to presidential politics, but there simply aren’t that many actual coal miners.

There are, for example, more ophthalmic laboratory technicians than people who actually mine coal. But at no point during the 2016 campaign did Trump ostentatiously don glasses.

Coal Mining and Processing. Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining. Mining is the first step in the dirty life cycle of coal. When coal mines move in, whole communities are forced off their land by expanding mines, coal fires. Early coal extraction was small-scale, the coal lying either on the surface, or very close to it. Typical methods for extraction included drift mining and bell pits. There are fewer coal miners than you might realize. mining coal (with a shovel, for itself — only 15,900 of which were extraction workers or helpers, mining.

extraction. Shallow, flat coal deposits are mined by surface processes, which are generally less costly (per ton of coal) 345 Coal Mining and Production. 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. In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining.


Surface mining is only economic when the coal seam is near the surface. This method recovers a higher proportion of the coal deposit than underground mining as all coal seams are exploited - 90% or more of the coal can be recovered. Large opencast mines can cover an area of many square kilometres and use very large pieces of equipment, such as draglines, power shovels, large trucks, bucket wheel excavators and conveyors.

The overburden of soil and rock is first broken up by explosives; it is then removed by draglines or by shovel and truck. Once the coal seam is exposed, it is drilled, fractured and systematically mined in strips. The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used.

Mine rehabilitation

Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining has finished.
