Sharon Torr, 58, and her husband Alan, 68, spent six months organising their unusual wedding venue.
Sharon, who works for the National Coal Mining Museum near Wakefield, where the celebration was held, was thrilled to have been allowed to get married underground.
She said: “It was wonderful.
“We wanted to get married somewhere completely different and we could have asked for nothing better than to be the first couple to tie the knot down a mine. Everybody had to wear helmets while travelling down underground and to the room we got married in but they were white and mine had a bit of bling on the front - it looked like a tiara.
“ I also had my hairdresser waiting at the top when I came back up to fix my hair because those helmets do ruin your look.”
All guests had to wear a small battery pack for their cap lamps to ensure they could see in the pitch black.
Sharon, whose father worked as a miner for 32 years, added: “I carried my battery pack because I didn’t want anything attached to my dress.”
She added: “It just looked wonderful.”
