Principles of Surface Mining of Mineral Deposits
Workings of the first kind are most efficient economically. In that case extraction of the mineral is done to the full capacity and the overburden rock is unloaded into the mined-out space. Stripping and mining of mineral deposit by deep-kind method are done layer wise (in slices) from the top downwards.
