Hi The following report was received from Health & Safety Executive, Silver House, 32 Silver Street, Doncaster. DN1 1HR. An accident of a somewhat unusual nature occurred at Snowdown Colliery, Kent on 22nd August, 1910. Two men were engaged in firing the boilers, when a sound "resembling a dull explosion" was heard, the corrugated iron roof was observed to rise a short distance, and the brick wall of the hopper, along its whole length, followed by a quantity of the slack, fell towards the boiler fronts, the roof falling upon the debris. The men (namely Charles Causer and Edward Thomas Kettle) were both killed, but showed no indication of having been burned, except by falling against the heated boiler fronts. The boilers were not damaged, except for some minor injuries to the fittings, apparently caused by the falling wall and roof. The brickwork of the flues was not disturbed, and the incandescent fuel on the fire grates was not blown out. The dampers were found to have been about three parts closed. The most probable cause of the accident appeared to me to have been that a leakage of acetylene gas resulted in the formation of a dilute accumulation under the corrugated iron roof, and that the draught of the furnaces drew it down, or a back draught from the flues ignited it, causing an explosion. The hopper wall was clearly too weak to support the load of slack, although it was stated that this had frequently been heaped up several feet higher that it was when the accident took place; and the rocking due to the explosion, accompanied by the removal of the steadying effect due to the roof, caused it to fall over. The wall when rebuilt was buttressed on its outer side. The accident was reported in The Dover Express and East Kent Newspaper, dated August, 26th, 1910. Kind regards, Penny The Waiting Miner, awaiting removal from Dover seafront to another location
