Surface mining allows the removal of coal from the surface rather than through underground tunnels. It requires the stripping away of earth, rock, and vegetation (collectively known as overburden) from above the coal deposit, which can then be mined and trucked away.

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including openpit, stripping, dredging and mountaintop removal.
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.
When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which
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. Regrading begins as coal excavation continues. Once coal removal is complete, final regrading takes place and the area is revegetated.

Strip mining is using a lot for coal, phosphates, clays, and tar mining. Typical Surface Mining Equipment online safety training course (short sample video included below) Online MSHA Part 46 training like the course above is a great way to jumpstart your MSHA compliance training.
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.
those involved with surface mine haulage road design with a complete manual of recommended practices that, if implemented, will promote safer, more efficient haulage routes. INTRODUCTION During the past 30 years, surface mine haulage equipment has developed from trucks capable of
"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.
Analysis of Safety Aspects And Mining Practices For Effective Ground Control in Surface Mining Pittsburgh, PA.
