Summary:
Knob Creek is an underground mine which develops Upper Kittanning coal seam utilizing room-and-pillar mining method.
The Knob Creek Mine is opened into the Upper Kittanning Coal seam through three drifts. Coal is produced on one underground section using a continuous mining machine and a continuous haulage system. The mine normally operates one production shift per day, 5 to 6 days per week.
The Knob Creek 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 typically extends a distance of 600 feet, depending on permit boundaries, projections, and conditions.
