the difference between an opencast mine and underground mining
diffrnce between opencast mining and underground mining
Underground versus Open Pit Mining Blogger. There are several different ways to mine underground. You can build spiral tunnels that circle the deposit, sink vertical shafts adjacent to the ore, or create adits, which are horizontal excavations into the side of a hill or mountain.

Opencast Mining
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

Opencast Mining (Quarrying): Methods, Advantages Disadvantages
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.
