TORONTO (http://www.cementprocesscrusher.com) – Massey Energy will now only send teams back into the Upper Big Branch mine, in West Virginia, next week, the company said on Thursday evening.
The company said earlier in the day that teams from Massey Energy and federal and state officials, re-entering the Upper Big Branch mine on Wednesday for the first time since rescue efforts after an explosion killed 29 people, did not encounter any water build-up underground that would hinder the investigation into the blast.
The teams emerged from the North Portal at around 18:00 on Wednesday, after completing an initial examination, during which the teams re-established communications between the two mine portals.
The company initially said that teams planned to re-enter the mine on Friday to travel to the longwall, conditions permitting, after borehole drilling scheduled for Thursday.
However, „due to delays associated with borehole drilling, the investigator teams are tentatively postponing their re-entry into the Upper Big Branch mine until the week of June 7, 2010,“ Massey said.
„Once borehole activities have progressed, methane readings are at more secure levels and the overall safety of mine investigators is ensured, the teams will implement their re-entry plan.“
The teams were initially withdrawn after their first entry on Wednesday, to confirm the safety of air conditions, but were able to re-enter and finish their initial exploratory mission.
