Consol Energy is scaling back operations at a northern West Virginia coal mine because of low market demand.
Pennsylvania-based Consol said Tuesday that it will idle some of the Blacksville No. 2 mine and reduce the schedule for its continuous mining operation to four days a week.
The mine employs 585 people. No workers will be laid off.
Consol says most overtime and other non-essential work will be postponed until normal operations resume. When that might happen is unclear.
Consol says the coal market is weak because of the mild winter and low natural gas prices.
Last year Blacksville No. 2 produced 4.3 million tons of coal.
Monthly production will drop by about 400,000 tons while the changes are in effect.
