10 Different Types of Mining Operations and …
Generally known as a small-scale mining method, this mining takes place in horizontal slices found along the ore body, and the bottom slice is the first to be mined. The excavated area is backfilled next, and then production continues upwards. With each production level, constant drifting occurs until the entire slice is mined, after which the slice is backfilled, and the fill …
