Coal is mined from the Pittsburgh Number 8 coal seam.

The mine accessed the Pittsburgh No. 8 coal seam by two portals: the Camp Run Portal and the Margaret Slope Portal. Coal was transported via overland conveyor belt from the slope to the Robinson Run Preparation Plant, located near Lumberport, Harrison County, West Virginia

Coal was mined from the 64-inch-thick seam by four continuous mining machine sections and one longwall section. The mine typically operated eight-hour production shifts, three shifts a day, six days a week. The mine was ventilated with six main mine fans. Coal was transported from active workings to the Margaret Slope Portal by a conveyor belt system and brought to the surface via a slope belt. Battery- and dieselpowered rail-mounted vehicles were used to transport supplies and mine personnel.

Robinson Run #95 Preparation Plant is located near Lumberport, in Harrison County, West Virginia. The current preparation plant began operation in 2009. It was built adjacent to the old structure, which was removed after being decommissioned.

The coal waste material that is produced as a result of cleaning coal at the preparation plant is deposited Into the Nolan Run Fine Coal Slurry Impoundment by 2 different means. A conveyor belt that originates at the preparation plant extends to a surface loadout structure that is located approximately 1.3 miles from the impoundment and from there; pans are used to transport the coarse refuse, into the Impoundment. The slurry material of the coal cleaning process is pumped through a 10 Inch plastic line into the impoundment. After, the slurry is deposited in the Impoundment; the water is treated and recycled for use in the preparation plant.
