In England, The Oaks explosion remains the worst mining accident, claiming 388 lives on 12–13 December 1866 near Barnsley in Yorkshire although in the first and main explosion only 340 died, fewer than at the Hulton colliery, but subsequent explosions claimed other lives during the night and the following day. The Hulton Colliery explosion at Westhoughton, Lancashire, in 1910 claimed the lives of 344 miners. An explosion in 1878, at the Wood Pit, Haydock, Lancashire, killed over 200 workers, although only 189 were included in the 'official list'. Another disaster that killed many miners was the Hartley Colliery Disaster, which occurred in January 1862 when the beam of the pumping engine broke suddenly and fell into the single shaft serving the pit. The beam blocked the shaft and entombed hundreds of miners. The final death toll was 204, most of whom were suffocated by the lack of oxygen. In the metalliferous mines of Cornwall, some of the worst accidents were at East Wheal Rose in 1846, where 39 workers were killed by a sudden flood; at Levant mine in 1919, where 31 were killed and many injured in a failure of the man engine; 12 killed at Wheal Agar in 1883 when a cage fell down a shaft and seven killed at Dolcoath mine in 1893 when a large stull collapsed. Scotland The worst mining accident in Scotland is the 1877 Blantyre mining disaster in Blantyre, Lanarkshire, which claimed 207 lives. Other fatal incidents occurred in the town in 1878 and 1879. Another serious incident occurred in the small Ayrshire mining village of Knockshinnoch in September 1950. For several tense days rescuers battled bravely against all odds to reach the 129 men trapped deep underground when a field above where they were working caved-in, flooding the mine workings with thick liquid peat, cutting off all means of escape. 116 were rescued but 13 died. A film, The Brave Don't Cry, was made about the disaster in 1952. The worst Scottish mining disaster in the 20th century took place at Auchengeich by Moodiesburn in September 1959, with 47 men killed. The total surpassed the 40 who had died in flooding at Redding, Falkirk in September 1923. Wales During the period 1850 to 1930 the South Wales coalfield had the worst disaster record. This was due to the increasing number of mines being sunk to greater depths into gas-containing strata, combined with
