PITTSBURGH, March 25, 2013 /PRNewswire/ -- CONSOL Energy Inc. (NYSE: CNX) has received approval from MSHA, state, and UMWA officials of its plan to re-enter the Blacksville No. 2 Mine, which was evacuated on March 12 when smoke was detected exiting the Orndoff shaft. (Logo: http://photos.prnewswire.com/prnh/20120416/NE87957LOGO ) Since that date, CONSOL Energy, working closely with federal and state authorities, pumped a sufficient amount of water into the mine to complete the water seal and remotely pumped eight isolation walls from the surface to seal off the fire area. This process was completed on Sunday, March 24 at 7:00 a.m. Analysis of the continuous mine atmosphere readings that the team has been taking indicates that gas levels remain steady and oxygen levels continue to decrease. As result, CONSOL Energy believes the fire has been successfully extinguished. CONSOL Energy Senior Vice President Chuck Shaynak said, "I am extremely proud of the successful collaborative effort from federal and state agencies, the UMWA, contractors/vendors and our employees on site who worked around-the-clock to remotely extinguish a fire in less than twelve days. Without their efforts, we would not be where we are today. Most importantly, we accomplished all of the work without an injury." CONSOL Energy and state and federal agencies will continue monitoring the mine atmosphere prior to re-entry, which is scheduled to begin at approximately 7:00 a.m. on Wednesday, March 27, if all atmospheric monitoring continues to indicate that it is safe to enter.
