Geologically, Stockton is located in the eastern portion of the Hazleton Coal basin, part of the Eastern Middle Anthracite coalfield. The Hazleton Coal basin is a relatively long, narrow synclinal fold striking east northeast – west southwest.

Stockton is primarily located in the Mammoth seam, which reaches thickness of over 20ft in the bottom of the basin, although there are significant reserves to be found in the overlying Primrose, Diamond and Orchard seams too.

Stockton Mine is an open pit mine located one mile from Hazleton, Luzerne County, Pennsylvania.

Plant and equipment at the site includes two large capacity hydraulic excavators and fifteen dump trucks as well as an anthracite preparation plant.

Atlantic Carbon Group practices concurrent mine reclamation at Stockton as part of our environmental policy, backfilling the mine pit as we move along the seam.

ROM anthracite enters the preparation plant where through a series of mechanical and chemical treatments is ‘cleaned’ of rock and other non-anthracite material and is then sorted into a range of sized anthracite products suitable for market. ROM anthracite is fed into a hopper from the ROM storage bay using a front end loader. Large rock is removed from the plant feed before being conveyed to a fixed grizzly screen and jaw crusher station that sizes the anthracite to 4” top size before feeding to the preparation plant.

The anthracite product is sorted into 8 standard sizes. Coarse refuse is collected on a belt conveyor and discharged to ground storage pile while fine refuse from the clarifier is collected in a sump and pumped to a disposal pond.
