Surface mining refers to the removal of the terrain surface to access minerals underneath. In particular, surface mining is used to retrieve sand, gravel, stones, coal, iron and other metals. There are five recognized types of surface mining, each with specific variations depending on the minerals being extracted.

Detecting and quantifying active mines and reclaimed areas are very important tasks given the effects of surface mining on the environment. In this paper, Landsat imagery for the years 1988, 1998, 2008, and 2017 was used to map the extent of surface mining and reclamation in the Jiu Valley mining area.

Surface miningis used when the orebody is close to the surface of the earth and can be excavated(dug out) forming a hole called an open pitmine. Explosives are used to break up the rock. The broken rock is loaded onto very large trucks, using front-end loaders, and taken away for additional processing.

The basic idea behind surface mining is to remove the surface stratum and to then remove the coal deposits that lie under them. Surface mining is pursued because it often has advantages over subsurface mining. These advantages include a safer working environment, more complete recovery of coal deposits, and the bottom line of cheaper production.
