"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.
Our Coal Program conducts inspections of active and inactive mine sites, with a number of personnel assigned to the Russellville field office.Inquire Now

Surface mining is an efficient method for mining some minerals, especially coal, from deposits near the surface. It uses very large equipment to strip away overlying material, extract the coal, and then fill in the mined valleys.Inquire Now
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.Inquire Now
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.Inquire Now
Coal mining: Coal mining, extraction of coal deposits from the surface of Earth and from underground. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy.Inquire Now
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 mining employs surface and underground methods to extract coal. A number of alternative technologies are associated with each method.Inquire Now
Surface mining and deep underground mining are the two basic methods of mining. The choice of mining method depends primarily on depth, density, overburden and thickness of the coal seam; seams relatively close to the surface, at depths less than approximately 180 ft (50 m), are usually surface mined.
