Markham Colliery explosion, 1937
A firedamp explosion at Markham Colliery, ignited by a faulty electrical coal-cutter after a roof break released trapped gas, killed 9 men by carbon monoxide poisoning on 21 January 1937.

Cause
A roof break near the coal cutter released trapped firedamp; a faulty replacement cover plate on the cutter's electrical controller compartment, where coal dust had collected in a small gap, produced a spark that ignited the gas. The inquiry described it as resulting from 'an unforeseen combination of abnormal conditions'.
What happened
Cutter operators arrived to begin work around 1:45pm; witnesses reported a flash and a crack from the machine, with one operator seeing a blue flame flash from its side. The main explosion followed around 2:40pm, described by witnesses as 'a crack like a shot out of a gun' accompanied by intense flame and smoke, travelling from the left bank toward the loader gate.
Investigation & inquiry
An inquest held on 18-19 February 1937 found the explosion was purely one of firedamp, with coal dust playing no part, caused by the coal cutter's faulty electrical design combined with the roof break; recovered safety lamps were found generally serviceable, and the jury concluded the company had maintained proper safety precautions.
Memorials & commemoration
Commemorated, alongside the colliery's 1938 and 1973 disasters, by the 'Walking Together' memorial trail of 106 steel figures (see the mine's own record).
