September 2, 2021 - Miners were evacuated Aug. 26 at CONSOL Energy's Enlow Fork mine in Enon, Pennsylvania, due to the accumulation of methane near a section's last open crosscut, the company said Aug. 31 in a Securities and Exchange Commission filing.

A Mine Safety and Health Administration representative issued an imminent danger order for the mine Aug. 26 when the methane accumulation was detected, according to the filing.

"The company promptly withdrew miners and removed all power sources from the applicable area of the mine and promptly addressed the methane accumulation," CONSOL General Counsel and Secretary Martha A. Weigand wrote in the SEC filing. "No injuries resulted from the condition described in the order."

The imminent danger order was promptly terminated following the company's corrective action, according to the filing.

CONSOL did not immediately respond to S&P Global Platts' request for additional information about the impact of the methane event on production.

Through the first half of 2021, Enlow Fork was the third-largest producing coal mine in Northern Appalachia with output of 3.59 million st, according to MSHA data. Enlow Fork is one of three mines that make up the Pennsylvania Mining Complex, the largest underground coal complex in North America.
