Opencast Mining an overview ScienceDirect Topics

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). As a consequence of this, whatever ecosystem that was present at the time prior
