These places are the typical home of BWEs such as the Bagger 293, which can work in tandem with LHDs (10[1])in flat areas of these places called “benches.” Acidithiobacillus bacteria congregate in these locations, where they oxidize toxic sulfides to produce a namesake “acid drainage”. 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 (-5[1])in these locations, which can then be backfilled with their discarded tailings. (10[3])The “surface” type (10[1])of these places, (10[1])which usually remove the (10[1])overburden located above (10[1])them, includes their “strip” and “open-pit” types. (10[1])For 10 points, name these facilities (10[1])for extracting minerals (10[1])and ore from (10[1])the ground. ■END■ (10[1])
