A Buchanan County Virginia coal mine had to be evacuated and shut down after a portion of the roof fell and may have sparked an underground fire. The Virginia Department of Mines, Minerals and Energy spokesman Mike Abbott says no injuries were reported in the incident at Consol Energy’s Buchanan Number One mine. Abbott says the department issued an order closing the mine indefinitely and dispatched a crew to join the federal Mine Safety and Health Administration and the company in sampling for gases, including carbon monoxide and methane. Pittsburgh-based Consol says about 120 miners were working in the mine when the incident occurred shortly before 10 O’clock yesterday morning. They say it was unclear whether the fall just caused a “flash” or whether a fire continued to burn underground. Officials say it could take up to 72 hours to determine whether the fire is still burning.
