Haystack Coal Company - Evanston, Wyo.
The Haystack Coal Mine is located 20 miles northeast of Evanston in southwestern Wyoming. The mine is a green-field site development and will produce a sub-bituminous coal from the Adaville Geologic Formation.
Haystack mines five spate coal seams, which range from 25 feet to 75 feet in thickness. The seams dip at an average of 20 degrees. The operation includes an 18-cubic-yard hydraulic excavator and a fleet of 100 ton haul trucks. The current economic mine life is projected to be 15 years. An additional coal lease application is currently being pursued which will extend the mine life for an additional 12 years.
The overall site development work has included removal of topsoil, building an access road and haul roads, constructing sedimentation ponds and ditches, grading the facility area, and establishing working benches in the pit.
