Mining engineers plan, develop, and operate mines, as well as other engineering excavations. They engineer the individual systems within a mining operation or large earth engineering project. Students gain extensive knowledge of the engineering systems necessary for planning and operating mines. They learn how to determine the economic worth of a mineral deposit and how rock behaves when excavated. They learn how to excavate, transport, and process minerals and coal. In addition, students use mining software to design, plan, and supervise mines. Emphasis is put on engineering mines to have minimal environmental effects.
