This is the Coal Authority's 'Interactive Map' page:

you have to zoom in to Amble then click what data you want to view from the menu on the left.
Worth a look at "Mine Entry"; first to the area south of Amble and to Acklington, and over at Shilbottle to Newton on the Moor for the vast number of shafts about that place.
Back at Amble they have a shaft marked in the trading estate, and on the road to Moor house and the beach road to Hauxley. The shaft markers/crosses are clickable but only the odd one has some extra info. The Shaft on the beach road to Hauxley says:
"This shaft has been secured to an unknown specification at some time in the past." The one in the School Field? at South Broomhill/ Hadston says
"a concrete stopping was built 10m down the drift and backfilled to the surface in November 1968"
Next of interest is "Development High Risk Area" this shows multiple bands of high risk passing through Amble which coincide with seam outcrops. (click 'coal outcrops' to check) Any of that could have worked by Bell Pits from medieval times!
