Quarry engineers, also known as mining engineers,

find the best way to extract raw materials from the ground, using blasting, drilling and excavation methods. Engineers also work in the processing plants, which refine raw materials, such as china clay, slate and stone (known as aggregates) for use in industries like construction.
Before a new mine or quarry is opened, your job as an engineer would be to work with minerals surveyors to decide if mining plans are commercially workable. To do this, you would:
· use ground-surveying techniques to chart the geological make-up of a site
· drill earth and rock samples for lab testing
· build up computer models of a site and its deposits
· Make recommendations to clients about how to proceed.
