The role of black miners in UK collieries is being celebrated in an exhibition at a Northumberland museum as part of Black History Month.
One of those - Mac Williams, 75 - worked at Dawdon Colliery in County Durham from the age of 16 and said the display brought back "good memories".
He said looking at the show's pictures felt like "standing at the pit shaft".
The Digging Deep, Coal Miners of African Caribbean Heritage exhibition is at Northumberland's Woodhorn Museum.
"I think it's important for the stories to be told to enlighten people's minds that we did have black miners working underground," he said.
"I really filled up when I saw my picture in there because I wasn't expecting it… Mac Williams from County Durham - local boy - has been recognised, been invited here today. Magic, marvellous.
"The miners must never be forgotten."
The exhibition forms part of the Black Miners Museum Project which has collected more than 240 names of miners and their collieries and carried out more than 60 interviews.
Exhibition curator Norma Gregory started her research 10 years ago when she discovered a miner in her own family history.
After World War Two men travelled from the Commonwealth to the UK in search of employment opportunities and some found work in collieries, settling in mining communities.
Ms Gregory said she hoped by bringing the project to the north-east of England more stories like Mr Williams' will be unearthed.
"Very little is known about black miners in this area from the local mining communities in the North East," she said.
Ms Gregory has spoken to other ex-miners to find out about their time underground.
"Time is pressing and this history needs to be documented while we still have our miners," she says.
Coming from foreign countries and standing out at majority-white pits meant some of the men down the mines faced discrimination, Ms Gregory said.
"Things were tough, were challenging, particularly for black miners, they did talk about experiences of difference," she said.
"Racism in the form of banter or names and nicknames which were offensive but they tolerated them."
But Mr Williams, who was born in the UK, said he had a different experience.
He said: "The mining community is excellent, the team spirit and the companionship and they treat everyone with respect, they certainly did me."
Digging Deep, Coal Miners of African Caribbean Heritage will be at the Woodhorn Museum, Ashington until Sunday 1 November 2020.
