[1] As the last remaining seam could be reached via the Brodsworth Colliery, the Bullcroft shafts were filled, using spoil from pit heaps and capped.
Bullcroft Colliery kept its landsale depot to deal with concessionary coal and retained a locomotive to work it for about a year afterwards.
The coroner gave a verdict of accidental death and asked that the colliery ensure that tubs are uncoupled from behind in future.
On 13 January 1937, Kenneth Oliver, 14, was killed in accident whilst he was uncoupling tubs from the internal conveyor system.
Oliver was under adult supervision, but his death lead to questions being raised in Parliament about boys working in mines.
The local community want the area to be landscaped and the spoil tip removed as has happened at other neighbouring collieries such as Askern, Bentley and Brodsworth.
