Surface mining equipment is similar to construction equipment (e.g., scrapers, bulldozers, drills, shovels, front-end loaders, trucks, cranes, draglines). Surface mining today is characterized by very large equipment (e.g., trucks that can haul more than 300 tons of rock, loading shovels with buckets greater than 36 cubic meters, draglines with ...

Traditional surface mining has left untold tons of minerals underground, simply because there was no way to get to it safely and efficiently. The Vermeer innovative Terrain Leveler surface excavation machines can work where explosives can’t, with top-down cutting that lets you reach valuable mineral seams and get the most product out of the ground as possible.
One of the biggest contributors to surface mining accidents is equipment and machinery. This is the case because for most if not all surface mines are mechanised operations meaning that machines
Nov 02, 2011 Surface mining requires large capital investment (primarily expensive transportation equipment), but generally results in: High productivity (i.e., high output rate of ore). Low operating costs. Safer working conditions and a better safety record than underground mining. 2 February 2016 7Prof. Dr. H.Z. Harraz Presentation 10.
Sep 22, 2015 More than 40% of the most serious injuries (fatalities and permanent disabilities, 2000–2007) in the mining industry involve accidents classified as struck-by or caught-in machinery and powered haulage equipment. For surface mining, collisions and driving over an unseen edge contributed to 3 to 4 fatalities per year between 2000 and 2007.
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.. Surface mining began in the mid-16th century [dubious ...
