The Wood Pit was one of at least 20 collieries in the area operated by the mining companyHaydock Collieries. It consisted of the Ravenshead mine and the Florida mine which were linked by a tunnel. The pit had been sunk in 1866. There had been at least two previous major explosions in the area, claiming 26 lives in April 1869 and 58 in December of the same year. The pit had a chronic problem with firedamp and as a precaution, explosives were never used, with miners relying on picks to manually extract the coal. In addition, workers were equipped with specially-designed safety lamps to prevent accidental ignition of gas. Most of the mine workers were from Haydock although some came from the neighbouring towns of Ashton-in-Makerfield, Earlestown and Newton-le-Willows. Many of the "drawers", who carried the coal from the mine, were sub-contracted, meaning that their names did not appear on the company's list of employees.
Explosion
On the morning of Friday 7 June approximately 250 men were working in the pit, 18 in the Ravenshead mine and the rest in the Florida mine. The explosion occurred at 11 am in the Florida mine and was accompanied by a collapse of the coal face. The workers in the Ravenshead mine were successfully evacuated but in the Florida mine there were no initial reports of survivors. Large crowds gathered at the pit head as rescue workers searched the mine and recovered the bodies. The bodies that were brought to the surface were reported to be "shockingly mutilated" by the force of the explosion. On 8 June the Chief Inspector of Mines Joseph Dickinson reported to the Home Secretary that he had joined the "explorers" in the mine but that attempts to recover the bodies or locate survivors were being hampered by the continued presence of gas and the failure of the ventilation apparatus. The best explanation of the presence of gas appeared to be that it had escaped from a notoriously dangerous coal seam deeper down the mine known as the "fiery 9ft", but the reason for the ignition was never found.
Aftermath
On Sunday 9 Julythe localAnglican priest Henry Sherlock, having spent the previous day visiting the bereaved families, was visibly distressed as he preached at St James the Great Church, using as his text John 14:18 By 10 July it was tentatively reported that there had been 182 deaths with 16 seriously injured survivors. Many families suffered multiple bereavements: the Boon family lost eight members including Nathan Boon and his four sons. A fund-raising campaign organised by Lord Derby raised £25,000 for the widows and orphans.
Memorials
Thirty of the men and boys who died at Wood Pit were interred in the graveyard of St James the Great Anglican Church, Haydock where a memorial was subsequently erected. A second memorial was erected closer to the site of the disaster in 2009.
