HANDOUT 7: Advantages and Disadvantages of underground mining 1. ADVANTAGES A) Underground mining (as compared to open pit exploitation) allows a mine operation to be largely having only Adits or head frames protruding above the surface. This enables the land above the zone of mining to be reclaimed for other uses, after mining has ceased.
