Why would you use one type of mining over another type of mining?

Because one type of mining may not be possible, may not be safe, or may not be economically feasible. Underground room-and-pillar mining for coal can only remove about 30% of the coal present, and requires a fairly thick seam of coal. Surface mining requires removing overburden that is covering the mineral you are mining- if that overburden is 500 ft thick, you could not afford the expense of moving that much rock. The Homestake gold mines were about 8000 ft deep- and followed the path of veins of high grade ore. Different geology, different needs.
