These places are the typical home of BWEs such as the Bagger 293, which can work in tandem with (10[1])LHDs (10[1])in flat areas (10[1])of these places called (-5[1])“benches.” (10[3])Acidithiobacillus bacteria congregate in these locations, where they oxidize toxic sulfides to produce a namesake (-5[1])“acid drainage”. (10[1]-5[2])Untopping (10[1])is a technique (10[1]-5[1])often used in Wales to extend the lifespan of these places. (-5[1])“Room (10[1])and pillar” and “longwall” techniques are used to produce (10[1])stopes (-5[1])in these locations, which can then be backfilled with their discarded tailings. (10[3])The “surface” (10[2])type (10[3])of these places, (10[1])which usually remove (10[1])the (10[1])overburden (10[1])located above (10[1])them, (10[3])includes (10[1])their “strip” and (10[1])“open-pit” (10[5])types. (10[9])For 10 points, name these facilities (10[1]-5[1])for extracting (10[2])minerals (10[2])and ore from (10[1])the ground. (10[1])■END■ (10[7]0[2])
