Mining and opencast mining in particular affect all components of ecosystems (Bradshaw, 1997).During opencast mining, material overlying the mined minerals, called overburden, is excavated and deposited in a heap. This heap can be located either inside the mine pit (an internal heap) or outside (an external heap).

The blast design parameters, such as burden, spacing, hole inclination, bench height, hole depth and diameter, stemming length, sub drilling pattern, blasting initiation etc. are controllable parameters ( Kulatilake et al., 2010 ). In opencast mining, bench design and blasting is a common method for overburden removal.

Variants of open pit mining are limited to a number of other surface mining methods, which include strip mining, high wall mining, and quarrying. Strip (open cast) mining is used extensively for the surface mining of important commodities such as coal and phosphate ores. Casting is the process of excavation and dumping into a final location.
