conveyor belts used in coal mines

When Were Conveyor Belts Invented? | A History of Conveyor Belts - SEMCOR

In 1905, conveyor belts were adapted for underground mining applications. The first six underground belt conveyors were installed in the Glass Houghton Colliery Company. The belts were 20 inches wide and 110 yards long. They moved at 200 feet per minute and together moved 500 tons of coal per day. 1957 — The Mobius Strip Conveyor Belt

Mining | Coal Mines

Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to the outside. Using a television camera, the operator can see and control the miner's progress.

Longwall mining involves the full extraction of coal from a section of the seam, or 'face' using mechanical shearers. The coal 'face' can vary in length from 100-350m. Self-advancing, hydraulically-powered supports temporarily hold up the roof while coal is extracted. When coal has been extracted from the area, the roof is allowed to collapse.
