Jamison Coal and Coke Company, based out of Westmoreland County, Pa., had been operating mines around Greensburg, Pa. for several years when they made a foray into the coal fields of Northern West Virginia by openeing three coal mines west of Fairmont in 1910. Jamison designed their mines and coal camps No. 7, No. 8, and No. 9. No. 7, at Barrackville, was sold to Bethlehem Steel in 1920. They kept operating No. 8, near Farmington, W.Va., until 1946. Then, in 1956, Jamison Coal and Coke sold their No. 9 mine, on the other side of Farmington, to Consolidation Coal Co. (They also sold a new mine they were developing, named Loveridge, to Consol, and it is still producing coal in the Twenty-First Century.) In 1968 an explosion at the No. 9 mine resulted in the death of 78 miners. Recovery of the bodies of the deceased lasted for another decade, and all of the bodies were not recovered.
In 1914, Jamsion No. 8 mine shipped more coal over the Baltimore and Ohio Railroad than any other mine in the Fairmont Coalfield. Jamison No. 7 was third, behind second place Federal No. 1.
