Wow, these abandonment plans are hard to decypher without knowing where the fault lines are! Any idea what year the drifts were driven Trev?? In deep hard, there are workings going up to Castle Blvd and part way under the University and extending almost to Beeston. My presumption would be they are from pit bottom, north side of the major faultline. Then the south west workings of Deep hard almost reach the Clifton Estate on the south side of the River Trent and extend under Ruddington. I'd presume from the bottom of the Stone Head Drift, several hundred feet below the north side workings. 1890's the dates to the north most workings and 1920's in the south west workings around Clifton Estate area.
The last workings of Wollaton were pretty close to the northern extent of Cliftons workings.
Now from what I recall your Uncle Tom telling me, the Trent actually flows down the fault line.

Here's the closest Clifton Colliery came to water bearing strata what was known as the "Bunter Sandstone" no known as the "Sherwood Sandstone measures" To the south of the last workings is a line called the "Permo Trias" This was from the Piper Seam workings 15's, 19's and 21's faces. The seam above is Deep Hard, last face in this area was 12's which would have been over the top of 19's. The seam below Piper is Tupton or Low Main as it's known in other parts of the coalfield. Two faces went under 15's and 19's at right angles with no water problems. How did they know where the edge of the Permo Trias line was?? There are BH marks on the map, BH=Bore Hole. No deep mining was carried out to the south of that line at Clifton or Cotgrave Collieries.
