These places are the typical home of BWEs such as the Bagger 293, which can work in tandem with LHDs in flat areas of these places called “benches.” (10[1])Acidithiobacillus bacteria congregate in these locations, where they oxidize toxic sulfides to produce a namesake “acid drainage”. (-5[1])Untopping is a technique often used in Wales to extend the lifespan of these places. “Room and pillar” and “longwall” techniques are used to produce stopes in these locations, which can then be backfilled with their discarded tailings.
