Mine shaft collapse in Edenderry, Co. Offaly, Ireland

An unknown mine shaft collapsed in Edenderry Town on Wednesday 28th September 2011. The collapse appeared in the middle of a tarmac footpath in a public park. Cornish Pixie and myself were asked by Offaly County Council to investigate the shaft and to help identify any other areas at risk from collapse. The shaft was about 4m deep with a level at the bottom leading off to the north. Prior to entering the level I observed low oxygen levels using a gas meter and the council brought in a 4-wheel remote camera to look at the level (a great toy for mine exploration!).

We soon deemed that the oxygen levels were OK for a short stay and did a quick survey of the workings.

Interesting stuff mcrtchly, thanks for posting.

How did the council's wheeled camera device cope? Could it deal with rocks, rails, mud and water etc?

Did you get to the ends?

What oxygen level was it and what level do you draw the line at?
