Acoustic and magnetic sweeps are commonly used for the collection of drifting mines. These sweeps are towed behind a ship and emit signals to trigger the mines' detonation sequences, rendering them safe. They are effective in clearing mines from shipping lanes and naval passages.

Coal mines can range in depth from a few hundred feet to over a mile deep, depending on the location and mining method used. Underground coal mines are typically deeper than surface mines due to the nature of the coal deposits.
Open cast mines, coal mines, silver mines, land mines.
There are various types of mines in the world, including open-pit mines, underground mines, placer mines, and drift mines. Each type of mine is designed for different geological conditions and extraction methods.
