Open pit mining pros cons - eHow

14/07/2020  The biggest advantage of open pit mining is the relatively low cost-extraction ratio. Open-pit mines are chosen when deposits of valuable minerals are found beneath the surface and where there overburden (overlaying rock or earth) is relatively thin. This means that no extensive tunnel network is required and no costly structural supports. Furthermore, large trucks can enter an open-pit mine,

Opencast Mining (Quarrying): Methods, Advantages ...

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 purposes. The mineral exposed is completely extracted. Opencast mining is also known as open-put mining, open-cut mining, surface mining and also as strip mining
