The following might be a bit band wagon jumping - but the recent collapses in local roads are all too familiar to me - brought up in Gravesend where dene holes were well known.
There has been a lot of local research by individuals and organisations. -
Subterranea Britannica http://www.subbrit.org.uk/ is long established, has a distinguished record and maintains a data base.
Kent Underground Research (KURG) has specialised in our area and I note that the redoubtable Rod LeGear is giving a talk to Gravesend Historical Association on 12th September about Kent Chalk Mines. There are also newer local organisations - like GIHS - and the North West Kent Family History Society has also produced research, particularly in brickworks.
A lot of work on the subject was published in the 1960s (and later) by the Chelsea Spelaeological Society - and I have put below a few references to their findings on Woolwich and Charlton from what I happen to have about the house and remember, Sub Brit have published far more
