Apr 24, 2017· After coal is mined, is it ready to be shipped. If the mine is close to a destination, trucks can carry the load. Using conveyors to move coal is another option for shorter distances. In 68 percent of cases, coal is transported by the railroad. This can be very expensive. Sometimes the cost of shipping coal by train is more than the mining costs.
The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used. Mine rehabilitation.
