Chile's President Sebastian Pinera has vowed to protect workers who draw attention to unsafe work practices.
Speaking to BBC's HARDtalk programme, Mr Pinera said Chile would do "whatever is necessary to have a more secure mining industry".
Mr Pinera, whose international profile has been boosted by the dramatic rescue of 33 miners, is currently in London.
He will later meet the Queen and Prime Minister David Cameron and present them with rocks taken from inside the mine.
Mr Pinera, who arrived in London on Saturday, was speaking less than a week after all 33 miners were safely rescued from the San Jose mine.
He told the BBC that during the 17 days before the miners were located in the shelter 700m (2,300ft) underground, he had always believed they would be rescued.
"I had a kind of inner voice that told me all the time they are alive," he said.
When asked if the rescue had been a miracle, Mr Pinera said it was "not only human effort" that had achieved the end result.
"I won't say it was a miracle, but I will say that we got some very important help," he said.
