Answer 1

Underground mining — Ore is removed through tunnels or shafts beneath the surface; used for deep deposits, low surface footprint but risks subsidence and worker safety hazards.

Open-pit mining — Large terraced excavation dug from the surface downward to extract near-surface ore; creates a huge open hole and large amounts of waste rock.

Placer mining — Minerals are recovered from stream, river, or beach sediments (panning, sluicing, dredging) where heavy minerals have been concentrated by water.

Strip mining — Surface mining that removes long strips of overburden to expose horizontal or shallow seams (commonly coal); land is stripped in successive parallel sections.
