Ventilation Plans

The Ventilation Plan for the Upper Big Branch Mine-South consists of a base plan and then subsequent approved revisions to both the plan and the ventilation maps. It is District policy to require a new base plan as the subsequent revisions become too cumbersome. The current base ventilation plan for this mine was approved on September 11, 2009 and revisions were approved and incorporated into the plan and ventilation maps.

As a part of the release of the accident investigation report release on December 6, 2011, there was the release of more plans and maps. They may be found on this page and are indicated by "added 12/6/2011".
