The Grosvenor Board of Inquiry was the first Board of Inquiry at a Queensland Mine in over 20 years. This is a summary video of the findings of the Board of Inquiry. The explosion in the 104 Longwall at Grosvenor was the first mine explosion in a Queensland Coal Mine in over 25 years. The lessons from the event must be made available to prevent similar events. Unfortunately I don't agree with the Board of Inquiry in that there was a second source of ignition for the second explosion, only 15 seconds after the first one. As a consequence we have made the Grosvenor Alternate Theory.
