· 3.1. Underground Mining. Typical underground mining operations begin either by clearing a section along the hillside where the coal outcrops or by tunneling downward to reach subsurface coal (Skousen and Zipper, 2021).Room-and-pillar mines progress by excavating linear channels into the coal seam and connecting the channels with rooms …

 · While underground mines are still the most common form of Coal mining in Appalachia, surface mining has grown considerably due to the practice of mountaintop removal -- a type of strip mining that utilizes explosives to blast as much as 800 to 1,000 feet off of the tops of mountains to access underlying coal deposits.

In the journal PLOS ONE, researchers estimate that between 1985 and 2015, an average of 21,000 acres was converted to bare earth and rubble in central Appalachia each year — an area about half the size of Washington, D.C. This analysis places the total estimate since the 1970s at about 1.5 million acres.

 · Surface mining is a broadly used mining technique that has increasingly replaced underground mining for a variety of resources [ 1 ], especially coal in the United States [ 2 ]. In Central Appalachia, most of this surface mining for coal is done in the steep, dissected landscapes of Kentucky, Tennessee, ia, and West ia.

Underground mine reserves are mined using continuous mining methods. Cooper Ridge Surface Mine Kopper Glo is in the process of permitting the Cooper Ridge surface mine. The Cooper Ridge Mine proposes to utilize the contour surface mining and auger mining methods on the Jellico coal seam. [2017, Environmental Assessment, p.24] Cooper …

If mountaintop removal mining can be stopped, what might a better future look like for Appalachia? Underground mining, though also rife with environmental problems, may provide a stopgap solution for energy and employment. Eventually, however, the coal will run out or the climate effects from burning it will become unbearable.

 · Historically, for an underground mine in this area to produce 4,000 clean tons a month is a pretty good number. We can probably recover somewhere around 1,000 to 1,200 clean tons per day with this highwall miner as we continue to iron out our problems. We're producing close to 1,000 clean tons a day now, or approximately 2,500 raw tons.
