2022-2-15 Conveyors, trams, and trucks move coal around mines, short distances from mines to consumers close to the mines, or to other modes of long-distance transportation. Trains transport nearly 70% of coal deliveries in the United States for at least part of the way from mines to consumers. Barges transport coal on rivers and lakes.

In the United States, about half of the coal carried by rail is transported by unit trains, groupings of 100 or more cars of 100- to 110-ton capacity each. Unit trains generally carry 10,000 to 15,000 tons of coal in a single shipment. A “dedicated unit train” is made up especially for movement between one point of origin and one destination.

China's coal is not only transported by rail but also uses railway-sea combined transport. It is estimated that 70% of coal transport depends on railways, 25% of coal transport relies on rail and water transshipment, and 5% relies on water transport. Fig. 8.13 shows the spatial distribution of railway transport and rail and water transshipment.

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

Slopes are driven at as steep an angle as is practicable for transporting coal by belt. Commonly, a pair of slopes is driven (or a slope is divided into two separate airtight compartments) or ventilation and material transport. Where the minimum coal-seam depth exceeds 250 to 300 metres, it is common to drive vertical shafts.

However, the large majority of mines today use diesel powered, rubber tyred vehicles (RTV's) to transport both personnel and materials within the mine, largely because of the flexibility of that system, with occasional caterpillar track vehicles for special purposes.
