  • Opencast Mining an overview | ScienceDirect Topics

    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 coverOpencast mining is also known as openput mining, opencut mining, surface mining and also as strip mining, the later term being commonly used in the USA for opencast mining of coal The overburden and the mineral, coal, are excavated in long strips of a few metres thickness and hence the operations are termed strip miningOpencast Mining (Quarrying): Methods, AdvantagesOpencast mining or quarrying of minerals is easier than mining by underground methods During quarrying the and rocks below which the minerals lie, are removed and in the initial stages, in a place which is not required in future g, residential or other purposes The mineral exposed is completely extracted, Opencast mining is also known as openput mining, opencut mining, surface mining andopencast mining % mineinformation opencast mining
