Mechanisation of existing mine work is distinguished from full automation. Mines still employ many people, partly because the underground environment complicates electromagnetic signals and electronics. Magnetic material and contaminated dust can interfere with equipment or short out processors. The comparison with magnetic torpedoes concerns their differing responses to the Earth's magnetic field in different locations. Underground conditions likewise need attention instead of assuming machinery will behave as it does at the surface.

Why mechanised mines still need human miners
Mine mechanisation still depends on human labor, while magnetic material, dust, and local conditions complicate electronic automation.
