Approximately 95 percent of all metal ore and nonmetal mineral production is by surface mining methods. As a result, 67 percent of all the metalore and nonmetal mineral mining wastes generated during the period was overburden and waste rock from surface mining, while only percent was waste rock from underground mining.
Removal of overburden to access the ore can pose major problems in storage and reclamation. The stripping ratio (wastetoore) for surface mining of metal ores generally ranges from 2:1 to 5:1, depending on local conditions. The iron ore is predominantly mined by opencast mining .
To sustain mining in the long term, Poltava must exploit the extension of the orebody into the Yeristovskoe deposit some 3km to the north. To carry out the plan, SRK has undertaken geotechnical and hydrogeological studies of the rock and soft overburden slopes of the pit and waste dump design.
Overburden Wikipedia. In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body.

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
Rock or Solid Mine Waste. Open pit mining has several stages of waste. First, to access the actual seams or veins of ore, the top layers of rock, or overburden, must be removed. Once the overburden has been removed, the seams can be extracted. When extracting the seams, the additional waste rock will be removed to get to the actual ore, called ...
