  14. People began using coal in the 1800s to heat their homes. Trains and ships used coal for fuel. Factories used coal to make iron and steel. Today, we burn coal mainly to ... Machines dig the coal and carry it to the surface. Some mine shafts are 1,000 feet deep. Th is is called deep mining, or underground mining.

  15. Coal is the main source of energy in China. In 2011, seven Chinese coal mining companies produced 100 million metric tonnes of coal or more. These companies were Shenhua Group, China Coal Group, Shaanxi Coal and Chemical Industry, Shanxi Coking Coal Group, Datong Coal Mine Group, Jizhong Energy, and Shandong Energy. The largest metallurgical coal producer was Shanxi Coking Coal Group.

  16. Mine Machines, Coal Cutting In the early days of using coal, loose coal would be gathered by hand where coal seams reach the Earth's surface (outcrop). Hand tools such as picks were used to get the coal. As seams were mined underground, sharpened hand tools were the standard equipment and continued to be used in small mines until the 1950s.
