  • 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)Opencast mining or quarrying of minerals is easier than mining by underground methods During quarrying the alluvium and rocks below which the minerals lie, are removed and dumped, in the initial stages, in a place which is not required in future for quarrying, residential or other purposesOpencast Mining (Quarrying): Methods, AdvantagesThe Yimin opencast coal mine was selected to conduct a case study The production of 100 tons of coal was used as the functional unit to evaluate the environmental risks in the stages of stripping, mining, transportation, processing, and reclamation A total of six environmental impact categories, ie, resource consumption, acidificationLife cycle assessment of opencast coal mine production: a
