The Bear Run Mine is a surface coal mine located near Carlisle, Sullivan County, Indiana, and is operated by Peabody Bear Run Mining, LLC. The mine started 1 producing coal from the Springfield 7, 6, 5, and 5A seams on September 13, 2010. The coal seams are accessed by two multiple-bench open pits and occasional highwall mining machines. The mine uses a combination of draglines, trucks and shovels, and dozer push to remove overburden and uncover coal in the Indiana No. 7, No. 6, No. 5A and No. 5 seams. The mine operates two 10-hour production shifts, seven days per week, producing approximately 20,000 tons of coal per day. The production process involves two draglines, shovels, and haul trucks. Maintenance is performed between production shifts.

The surface-mined run-of-mine (ROM) coal from Bear Run mine is delivered by off-road truck to a 270-tonne hopper. Reclaimed at 1 800 tph, the ROM coal is conveyed to a crushing and screening building for reduction to 5 inch top size and then transported to one of the two 50 000 tonne raw coal stockpiles. The raw coal is reclaimed at the rate of 1 360 tph and transported to the preparation plant. The coal preparation plant is designed to process 1 450 tph of raw coal in two parallel circuits with future expansion to 1,800 tph allowed for in the design, equipment sizing and floor space allowance. Heavy medium cyclones wash the +1 mm coarse material. Water-only cyclones and spirals wash the -1 mm fines. Vibrating centrifuges provide final dewatering of the coarse coal, while stack sizers followed by screenbowl centrifuges dewater the fine coal. The plant employs a 145-foot diameter thickener for fine refuse recovery and water clarification. The design also incorporates a PLC control sys ........
