How to Become a Mining or Geological Engineer

Mining or geological engineers guide mining and other resource-extraction efforts to ensure safety and reduce waste. One might design or oversee the construction and inspection of mine shafts and tunnels, for instance. Mining engineers also conduct statistical analyses and create computer-aided design plans. Again, those with an environmental engineering background typically focus on the environmental impacts of these initiatives.

Degrees, Certifications & Licensing

  • Minimum education requirement: While a bachelor’s degree in mining or environmental engineering is the most common entry-level education requirement, employers increasingly prefer to hire candidates with master’s degrees. Environmental engineering graduates tend to focus on water or air pollution prevention and sustainability, ensuring mines are safe and environmentally sound. As such, they are often called mining safety engineers. Candidates searching for research positions usually need doctoral degrees.
  • Popular professional certification(s): Certified Mine Safety Professional from the Society of Mining, Metallurgy and Exploration
