Found some information of the Stone Head Drift, which was originally called the No1 Conveyor Drift, never heard it called that before.
It was originally sunk from the Deep Soft seam, this I didn't know, in 1922 down to the Deep Hard seam, which was the bottom when I served my time there, except it started from the Deep hard seam at that time. Deep soft was the seam above DH and it had it's own pit bottom which was broken into when a surge bin was installed around 1965.
The drift was extended down to the Piper Seam in 1942 then driven down to the Low Main seam, (Tupton) in June 1946 and finished in March 1947, depth was 789ft and Low Main seam was 2ft 10" thick.
According to logs, the drift was 670 yards long from Deep soft to Deep hard at 1:8 3/4.
Some of this might confuse some readers, but there is a large fault that the drift went through, hence pit bottom was deep soft and at the bottom of the drift was deep hard.
As stated, when I worked there, the pit bottom we used was in the Deep Hard seam and the drift ended at the Deep Hard seam on the opposite side of the fault. The extension to Low Main had been sealed, which thinking back puzzles me as the main roads could all have been kept in Low Main instead of drifting down and up through the seams worked over the years.
