  • Underground mining (hard rock) - Wikipedia

    Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal ...

  • Home | Indiana Geological & Water Survey

    Underground coal gasification (UCG) is a technology that can complement traditional methods of coal mining and surface gasification. This technology works by converting coal into a combustible gas (syngas) that can be used for industrial heating, power generation, and the manufacture of hydrogen, synthetic natural gas, or diesel fuel.


    Coal is produced from underground mines using longwall or room-and-pillar mining technology. Longwall mining consists of developing the coal in rectangular blocks called "panels," using room-and-pillar mining equipment. Longwall panels are developed to maximize the recovery of coal and are up to 900 feet wide by 10,000 feet long.
