Bullcroft Colliery was a coal mine situated by the village of Carcroft north of Doncaster.
 The Bullcroft Colliery Company was formed in April 1908 and sinking of the shafts commenced immediately.
 In January 1909, at a depth of 100 ft , a water course yielding over 1,000 USgal per minute was struck, it was capped back and sinking continued but only a month later, at 180 ft , another water course, big enough to be described as a "subterranean river", was struck - too much for the steam operated pumps to cope with.
 Electric pumps were brought in to cope with the flow but even with a capability of 6,250 USgal per minute they couldn't cope and sinking was stopped so the full situation could be assessed.
