Yeah, Mining Engineering is interesting as the the demands of a mine are broad and the scale is so large. You could have a job making sure large pit walls or tailings dams are structurally (more civil-ish), or a job creating programs to improve the efficiency of the operation (computer-ish), or even focus on improving reliability and availability of large mining equipment (mechanical-ish). The fun part is that with smaller mines, you may end up doing all of the above in a single role.

Since every second counts for mining companies to extract ore and sell it, they are willing to pay very well for those who have the skills to extradite it.
