A walker who plunged more than 50ft (15m) down a mineshaft says a rucksack cushioned his fall and saved his life.
Andrew Williams, 51, was trapped for hours after falling down the disused shaft near St Just in Cornwall on Sunday.
He said he was “amazed” he survive the fall which saw him end up on a narrow ledge.
Mr Williams was airlifted to hospital with a broken pelvis after a six-hour rescue operation.
Mr Williams had been walking with a group of people when he went to explore the mine opening in the Cot Valley.
But a wooden cover gave way and he fell onto the ledge.
He put his survival “down to a full rucksack that took the brunt of the impact and saving me from banging my head”.
Rescuers brought Mr Williams to safety through a narrow “hourglass” gap.
He said the “professionalism and knowledge” of the rescue teams was “amazing” and thanked them for “without a doubt saving my life”.
He had “many dark moments” during the ordeal but focusing on his family and friends “got me through it”, he said.
Mr Williams has since undergone an operation on his pelvis at the Royal Cornwall Hospital in Treliske and said he would “hopefully be back walking soon”.
