A method of extracting minerals and ores from beneath the Earth’s surface, this approach becomes necessary when resources are located at significant depths, making surface extraction impractical or environmentally undesirable. Various techniques are employed, including room-and-pillar, longwall, and drift mining, each tailored to the geological conditions and the nature of the deposit. For example, coal seams found hundreds of meters underground are commonly accessed and extracted through these subterranean methods.
This form of resource recovery is vital for obtaining essential materials required for numerous industries, from energy production to manufacturing. It provides access to deposits that would otherwise be unattainable, contributing significantly to economic development. Historically, its advancements have been crucial in meeting increasing global demands for raw materials, fueling industrial revolutions and technological progress. The development of safer and more efficient practices has also reduced the environmental impact associated with it over time.
