Summary:
The Heilwood Mine uses a room and pillar method of mining. A continuous miner with attached haulage develops main entries. After the mains are established butts, rooms, and/or panels are developed off of the mains. The length of the rooms and/or panels can typically extend a distance of 600 feet to over 6,000 feet, depending on permit boundaries, projections, and conditions.
The Heilwood mine is opened into the Lower Kittanning coal seam through three drifts; it then accesses the Brookville coal seam via an inter mine slope. Coal is produced from one underground section using an auger type continuous mining machine and a continuous haulage system. The mine normally operates one production shift per day, five to six days per week. Coal is transported from the underground section to the surface coal handling facility via a series of underground and surface conveyor belts.
