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.
Coal surface mining involves a series of steps: 1) explore for deposits of coal near the surface, 2) prepare the surface for the mining operation, 3) drill, 4) blast, 5) remove the overburden, 6) load the coal, 7) haul the coal, and 8) reclaim the surface of the land to what it was like before mining.
WIRTGEN surface mining has proven its worth as a tried-and-tested technology in numerous coal mining projects. It was no surprise, therefore, that the 6-month trial phase with defined target performance levels agreed upon between NAC and WIRTGEN was a resounding success:
Open-pit coal mining as opposed to strip mining has only recently been practiced to any large extent in the West, and its impact on national coal productivity has yet to be felt. Western surface coal mine productivity will range from 50 to 150 tons per man-day or irore.
Surface Coal Mining. The primary methods of surface coal mining used in Pennsylvania are: Strip Mining: Layers of soil and rock overburden are removed the coal exposed coal seam is excavated.The area is then backfilled, regraded, and replanted during the reclamation process.
Mining the Coal. Coal miners use giant machines to remove coal from the ground. They use two methods: surface or underground mining. Many U.S. coal beds are very near the ground's surface, and about two-thirds of coal production comes from surface mines.

The U.S. Government's Official Website for the Office of Surface Mining Reclamation and Enforcement (OSMRE). OSMRE's business practices are to reclaim abandoned mine lands (Title IV), regulate active coal mines (Title V), and apply sound science through technology transfer.
Coal was produced at two surface mines comprised of 1,810.9 acres and three underground mines comprised of 172.5 acres. The permitted acreage for the underground mines does not include the shadow area, which is the footprint of the underground disturbance transposed to the surface …
comparison of the total injury rates in US coal mines. The injury rates have declined both in surface and underground mines. However, the total number of injuries per one million employee-hours for underground US coal mines in the last decade is three to four times higher than for surface mines.
Layers of rock and dirt above and between the coal seams are removed. Coal seams are removed with excess soil and rock placed in an adjacent valley. Large scale earth moving equipment is used to excavate and remove coal from lower layers. The equipment used depends on the method and scale of the surface mining method being employed.
Coal is mined in Appalachia by both surface and underground mining techniques. Surface coal mining methods in the steep terrain of the central Appalachian coalfields include mountaintop removal, contour, area and highwall mining. Coal mining operations are found in Kentucky, West ia, ia ...
Surface mining began in the mid-sixteenth century [dubious – discuss] and is practiced throughout the world, although the majority of surface coal mining occurs in North America. It gained popularity throughout the 20th century, and surface mines now produce most of the coal …
Mining for coal depends on many variables. The geology and environmental aspects play a vital role, but depth and quality of the seam is what brings home the bacon. Depending on where the seam (profitable bed of coal) is located, extracting this black gold can require a smorgasbord of options. Coal ...
"Strip mining" is the practice of mining a seam of mineral, by first removing a long strip of overlying soil and rock (the overburden).It is most commonly used to mine coal and lignite (brown coal).Strip mining is only practical when the ore body to be excavated is relatively near the surface.
This industry includes auger mining, strip mining, culm bank mining, and other surface mining, by owners or lessees or by establishments which have complete responsibility for operating bituminous coal and lignite surface mines for others on a contract or fee basis.
