Hernandez, Daniel. "A 'miracle' in Chile, but mining accidents are often tragedies across Latin America." The Los Angeles Times. In Chile, 33 miners have been rescued within the dramatic incident recounted earlier, but one other forty five died in other accidents that very same 12 months. Most mining accidents achieve little media attention, particularly those involving few casualties or going down in developing nations. Many accidents occur when the mine props collapse because of earth tremors. Those slices drop instantly onto a continuously shifting conveyor, which carries it to a haulage shaft that lifts it out of the mine. Blasting can ignite these gases, leading to deaths from each the explosions themselves and the next collapse of mine structures; a methane-gas explosion killed these 29 miners in West Virginia.

The longwall technique can get well as much as ninety p.c of the available ore. Longwall mining is extraordinarily efficient. Rather than drilling by means of the ore deposit, a longwall machine cuts across it, shaving off slices up to 600 feet (182 meters) long. As the machine progresses into the ore, the helps move with it, permitting the world behind it to collapse and fill within the excavated space.
