Foresight Energy LP (NYSE:FELP) on March 31 reported that it has received permission from the U.S. Mine Safety and Health Administration to temporarily seal the entire Deer Run Mine in Illinois to reduce or eliminate oxygen flow paths into the mine as part of its continuing efforts to extinguish the combustion event which began in March 2015.
The process of sealing the mine will begin immediately. At this time, Foresight is uncertain as to when production will resume at Deer Run.
U.S. Mine Safety and Health Administration data shows that Deer Run produced 5.6 million tons in 2014. It had strong production in the first quarter of last year, then much-reduced output in the second and third quarters, and no output in the fourth quarter of 2015. 2015 production in total was 1.9 million tons.
Foresight is a leading producer and marketer of thermal coal controlling over 3 billion tons of coal reserves in the Illinois Basin. Foresight currently owns four mining complexes (Williamson, Sugar Camp, Hillsboro and Macoupin), with four longwall systems, and the Sitran river terminal on the Ohio River.
