Foresight Energy LP (NYSE: FELP) said April 1 that carbon monoxide readings in excess of actionable levels (a mine-specific carbon monoxide threshold requiring mine management to evacuate the mine) were detected on March 26 at Hillsboro Energy LLC’s Deer Run longwall mine located near Hillsboro, Illinois.
All underground employees were safely evacuated. The carbon monoxide readings have declined and are trending down, said the April 1 statement. Mine level management is working with federal and state officials to evaluate and correct the situation. It is expected that mining activity will resume after it is determined that conditions are safe and the U.S. Mine Safety and Health Administration has approved a plan to re-enter the mine.
Foresight Energy said it does not expect any interruptions in coal deliveries as a result of this event as sufficient inventory exists at the mine such that no impacts to customers are expected.
Foresight Energy LP is a leading coal producer in the Illinois Basin region of the United States. Murray Energy out of Ohio, another major coal producer, is currently working on a takeover of Foresight.
