Coal Mining and Processing

The overall coal mining process consists of several sequential stages: (1) exploration of a potentially economic coal seam to assess minable reserves, environmental issues, marketable reserves, potential markets, and permitting risks; (2) analysis and selection of a mining plan; (3) securing the markets; (4) developing the mine; (5) extracting the coal; (6) processing the coal if necessary; and (7)

Little Eska engine a reminder of Matanuska Valley's coal

May 10, 2018Coal from the mine was initially sledded to the railroad tracks. The owners of the Eska Mine encountered problems, and the AEC, needing a reliable source of coal for its locomotives, purchased the mine in June 1917. It installed a narrow-gauge spur from the Matanuska line to the mine that same year. That spur was where No. 5 found a home.
