Last course I did at Rhondda Mines Rescue was 14 years ago, they were mostly geared up for safe entry to confined spaces in those days.
The future of mines rescue (in its present form) seem limited?
From Wiki.
"On 10 April 2014, Reuters reported that the British government is to give UK Coal a ten million pound loan to help fund the closure of its two remaining deep mines. The company will carry out a managed closure of the deep mines by Autumn 2015 and will seek a buyer for its surface mines."
