I thought bell pits were normally totally backfilled with the spoil dug from a new, adjacent one? In which case minor subsidence at the shaft top would be the only likely change over time. If the spoil heaps were subsequently removed it suggests that the tops were levelled and stable. Isn't it more likely to be crown holes opening up over shallow horizontal (pillar and stall) workings?

We have these show up in are fields a lot normally is a slight tunnel collapse , once the fields get ploughed you see more show up after the heavy farming machines go over them . I did read a part on there saying in one he saw different tunnels going of in other directions so could be at a large tramway junction ?
