The applicant intends to mine coal at a maximum production rate of 800,000 tons per year utilizing room and pillar methods. Five entries were driven into the Red Arrow Seam. At 2,800 feet in depth, ramps were driven up and into the Dirty Jack O'Lantern Seam, which lies approximately 30 feet above the Red Arrow Seam. Dorchester is equipped with four continuous miners which are currently being used for the advance and pillaring operations. Coal from the mine is transported to the main stockpile via conveyor. From here, the coal is crushed in a rotary breaker and rejects are separated from the coal utilizing a heavy media wash plant. Clean coal is stockpiled and transported to the load-out near Florence. Reject material is thickened with Nalco chemicals 8872, 8874 and 8852 and passed through a belt press for dewatering. The dewatered coal processing waste is then trucked to the coal processing waste pile.
