Opencast mining operations involve huge quantities of overburden removal, dumping and backfilling in excavated areas. A substantial increase in the rate of accumulation of waste dumps in recent years has resulted in greater height of the dump for minimum ground cover
Open-pit mining is to be considered one of the most dangerous sectors in the industrial world. It causes significant effects to miners health, as well as damage to the ecological land. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths.
Overburden at a coal mining site. 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.
The opencast mine is spanned by the overburden conveyor bridge. This equipment complex removes the overburden sand, gravel and clays from above the lignite seam and transports it directly over the pit by the shortest route to the other side of the mine.

Opencast mining is a mining process that generates huge amount of rock waste. Waste rock material generated along with mining is called mine overburden (Prashant et al., 2010). During opencast mining, the overlying soil is removed and the fragmented rock is heaped in the form of overburden dumps (Ghosh, 2002).
