We delved deep into the Sunderland Echo archives to find these 19 images from the pits of the Wearside area.
From canteens to pit cages, ponies to winding gear, we have got lots of reminders of a huge industry.
Take a look and if you have more memories to share, get in touch and tell us more.
1. Last day at Vane Tempest
The last shift at Vane Tempest. Does this bring back memories?
2. Herrington Pit
The last of the Herrington miners pictured at the pit in 1986.
3. Last shift leaves Dawdon Pit
Forty miners were hauled 1,000 ft to the surface of Dawdon Colliery at the stroke of midday on July 25 1991. It marked the end of production at the colliery.
4. Saying goodbye to Houghton in 1981
Houghton was the county's oldest pit when it closed in 1981. Did you work there and what are your memories of it?
