It remains unknown when the Blacksville No. 2 mine will resume production.
Mine examiners at the Blacksville No. 2 mine have completed an examination of the haulage trackers and belt entries between the Kuhntown shaft and Wanna shaft mine areas. Examiners have been checking airways and mine rescue teams have completed cleaning one seal site in the Kuhntown area and are preparing framework for the seal while they work to clean additional seal sites, according to an update issued Friday from CONSOL.
Water continues to be pumped out of the mine and an additional pump is being installed Friday to help this effort. CONSOL's team homes to have the mine examined by April 8. A reopen date remains unknown.
CONSOL Energy crews installed permanent stoppings at the Kuhntown and Orndoff seal sites of the Blacksville No. 2 mine. The teams continue to inject nitrogen into two boreholes and plan to begin injecting nitrogen into a third borehole Wednesday. Dewatering pumps are running to maintain a water level that allows the team to travel by rail to the Orndoff shaft site and to prepare sites for final, permanent seals.
CONSOL received approval of its plan to examine a portion of coal mined from state, federal agencies and the local union, according to a news release from the company. The teams implemented this plan at 11:15 a.m. as certified mine examiners entered the mine.
CONSOL Energy's team continues to monitor the situation. It's unknown when the Blacksville No. 2 mine will resume production, according to the news release.
At approximately 8:56 a.m. on March 27, the first two CONSOL Energy advance teams entered the Blacksville No. 2 mine following necessary elevator checks at the Kuhntown portal, according to CONSOL Energy.
The teams conducted "an initial examination of the active mining area near the Kuhntown portal, repaired one discharge line, isolated electrical power in the Kuhntown bottom and established a source of electrical power through one borehole to the Kuhntown bottom," according to CONSOL Energy.
Weekly electrical checks have also been performed by the teams on five vehicles. CONSOL Energy said that several compressed air de-watering pumps have also been installed so that the teams can expand their examination to the Orndoff shaft of the mine.
According to CONSOL, gas levels have remained steady since entering the mine and consistent CO readings have confirmed that the fire is out.
On March 29, the teams were brought to the surface for approximately six hours. At this time, officials evaluated the increase of oxygen levels at established boreholes from the surface, and the teams were able to reenter the mine at approximately 4:30 p.m. that day.
CONSOL Energy said its team will remain on-site around the clock to monitor gas levels and to oversee the situation. It is still unknown when production at the mine will resume, according to CONSOL.
More information will be provided when it becomes available.
CONSOL Energy has received approval from MSHA, state, and UMWA officials to re-enter the Blacksville No. 2 mine, which was evacuated on March 12 when smoke was detected exiting the Orndoff shaft, according to a news release from CONSOL.

Blacksville No. 2 Mine produces approximately 400,000 tons of coal per month under normal operations, according to CONSOL.
CONSOL Energy believes the underground fire at the Blacksville No. 2 mine that had been burning since Tuesday, March 12, has been extinguished. Crews pumped water into the mine to complete the water seals. Mine atmosphere readings indicate that gas levels remain steady and oxygen levels continue to decrease, according to an update from CONSOL.
A completed re-entry plan for the mine is being reviewed by MSHA, state and UMWA officials Thursday. Once the mine has been fully sealed, the team will work with state and federal agencies to monitor the mine atmosphere to determine when it will be safe to re-enter the mine.
As the mine remains idle, employees are being notified that they are eligible to apply for unemployment benefits and their current benefit plan remains in effect, according to CONSOL. CONSOL said it has been working closely with federal and state mine officials and local union officials to put these employees back to work as soon as possible.
Crews are preparing to begin pumping nitrogen at the Blacksville No. 2 mine, in an effort to deplete oxygen, into an additional borehole, according to an update from CONSOL Energy.
The drilling process for the isolation walls continues and six of eight boreholes have been completed from the surface. All materials needed to pump the isolation walls are on site and pumping was set to begin at 3 p.m. Wednesday. Drilling sites near the Kuhntown portal are prepped and drilling rigs are on standby if additional boreholes are needed.
Crews remain on site around the clock monitoring gas levels in the mine.
We will provide more information as it becomes available.
Crews at the Blacksville No. 2 mine continue to monitor gases in the mine atmosphere.
The level of CO is decreasing, according to MSHA. Tuesday morning, 11.4 million gallons of water have been induced and 6.2 million cubic feet of nitrogen have been injected into the mine.
Material to install remote seals is expected to be delivered to the mine late Tuesday or Wednesday.
CONSOL, working with federal and state authorities, made progress to extinguish the fire that caused 121 day shift employees to evacuate the Blacksville No. 2 mine on March 12 at 2 p.m., according to a news release from CONSOL.
Fifteen strategically placed boreholes were drilled into the mine, while two of the holes are being used to inject water into the affected area, with one positioned directly over the fire. One borehole is being used to inject nitrogen, a gas used to deplete oxygen, another borehole is being used to measure the water level in the mine, another is monitoring the mine atmosphere and eight boreholes will be used to install remote isolation plugs.
Crews detected elevated gas levels in the mine Saturday, which built up as a result of CONSOL getting water to the fire area and reducing oxygen content. As a precaution, the Kuhntown portal building was evacuated for twelve hours until the levels were safe.
Five boreholes have now been drilled into the Blacksville No. 2 Mine in Greene County, Pennsylvania after smoke was detected exiting the Orndoff shaft on Tuesday, Amy Louviere of MSHA said Friday.
A camera has also been lowered into the boreholes, and smoke has been detected at varying levels. Louviere said temperature registered 100 to 105 degrees from one of the boreholes. This borehole is believed to be closest to the fire.
As of 4:02 p.m. on Friday afternoon, 1.21 million gallons of water have been pumped into the mine at an estimated 125,000 gallons of water per shift, according to Louviere.
Emergency work at the mine will continue through the weekend, Louviere said.
Emergency work continues at the Blacksville No. 2 Mine in Greene County, Pennsylvania after smoke was detected exiting the Orndoff shaft on Tuesday, according to Jesse Lawder of MSHA.
The first borehole has been drilled to a depth of 907 feet and it is estimated that the drill will intersect the mine Thursday afternoon. The second borehole is down a depth of 45 feet, and holes three, four, and five are all in the preparation stages, according to Lawder.
Lawder said water is still being trucked to a borehole and dumped into the mine. The mine is also in the process of laying a waterline from a pond near the Orndoff fan to the first borehole.
Once the first borehole intersects with the mine, a camera will be used to look underground and water from the pond will be dumped into the mine, according to Lawder.
Recent readings at the Orndoff fan indicate that 370 ppm of CO is in the shaft, Lawder said.
As of 4 p.m. Thursday, approximately 800,000 gallons of water were pumped into the mine through the Orndoff shaft. Infrastructure is being built to accommodate trucks and pumps to deliver water from additional sources, according to CONSOL.
CONSOL, as well as UMWA, MSHA and the state of West Virginia are continuing to maintain presence around the clock at the mine and will be working together to gain control of the fire, according to Lawder.
CONSOL Energy has drilled the first of three boreholes down approximately 157 feet, near where the fire is believed to be located, according to MSHA.
MSHA plans to begin drilling the second hole, which will be located down wind of the suspected fire area, also on Wednesday. Officials plan to monitor the fire atmosphere through the borehole. A third hole will be drilled approximately 300 feet from the first one, according to MSHA.
MSHA said approximately 250,000 gallons of water have been induced since midnight. CONSOL is in the process of installing an 8-inch line to a 1,000 gallon per minute pump and is injecting Nitrogen into the sealed area.
Crews at CONSOL Energy's Blacksville No. 2 mine were evacuated Tuesday around 2 p.m. after smoke was detected exiting the Orndoff shaft at the mine near Wayne in Greene County, Pa.
All 121 day shift underground employees evacuated safely through the Kuhntown portal, according to Lynn Seay with CONSOL. No injuries were reported.
Overnight Tuesday, CONSOL Energy, working with federal and state authorities, identified the general location of a fire burning underground and created a plan to contain it and extinguish the fire.
The plan includes two primary strategies, including mobilizing all resources to maximize the amount of water that can be injected into the mine near the site where CONSOL believes the fire is located and to conduct air sampling to monitor CO and methane levels in the mine.
CONSOL opened an existing borehole at the Orndoff shaft around midnight Tuesday and by 8 a.m. Wednesday, 125,000 gallons of water had been pumped into the mine. The company is in the process of deploying three vertical drilling rigs to drill additional boreholes near the Orndoff shaft, which will allow crews to increase the volume of water that can be pumped into the mine, according to a news release from CONSOL.
One of the rigs is already on-site, said Seay, and it began drilling operations at 9:30 Wednesday morning. A second rig should arrive by 5 p.m. Wednesday and is in the process of being shipped from CONSOL's Bailey mine.
Tuesday night, CONSOL Energy canceled midnight and Wednesday day shifts at the mine and today confirms that all shifts will be canceled so that the remediation plan can continue.
All CONSOL Energy hourly employees at the Blacksville No. 2 Mine and Prep Plant can tune into AM 1170 and FM WRLF 94.3 for future work announcements. It is unknown at this time when mine operations will resume. No personnel will re-enter the mine until it is determined that it is safe to do so.
