In 2010, people everywhere were riveted to the story of the 33 miners in Chile trapped 2,300 feet (seven hundred meters) beneath the Earth's surface in a copper and gold mine. An underground coal mine can drive 2,500 toes (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.

Many accidents happen when the mine props collapse as a consequence of earth tremors. It involves drilling a section of ore at the very backside of the deposit and then blasting to make the roof collapse. A last cross drills by means of the pillars to recuperate the ore there, permitting the roofs to collapse behind the machine because it leaves every room.

The machine strikes by the ore, creating rooms and pillars, till the complete deposit is coated. When the ore deposit in comparatively slim, shorter cuts are made. An operator then drives a drill by way of the ore, making a drift, or a horizontal minimize, from one side of the deposit to the opposite.

Breathing in welding fumes, radon or mercury (often present in mines) also causes respiratory diseases.
