The mine rescue teams found the bodies of the remaining four coal miners bringing the total of confirmed deaths to 29. Now, the recovery of those bodies begin. Then the mine is restored to some level of safety for the investigative teams to do their week(s) long exploration, then interviews of miners, company officials, and others to try to get to the bottom of what happened. Then regulatory bodies will set down and decide what new laws and regulations, if any, are needed to prevent something like this from happening ever again.
On a personal note, I will be busy with many of the things listed above for a long time I suspect. Keep the community and myself in your prayers.
