RegionRhondda Cynon Taf
Primary typeExplosion
Associated typesGas / Asphyxiation
Fatalities2 (Named as Lumley Ellis (Aberystwyth) and William Davies (Llandinam) by NMRS; Durham Mining Museum's own fatalities register instead gives "Ellis, L., aged 40" and "Davies, H., aged 23", both sinkers, both dying on 20 May -- two days after NMRS's stated accident date of 18 May. Both sources agree the cause was an explosion of gas while sinking, and the surname/occupation match makes clear this is the same incident; the exact date and Davies's forename are not reconciled here.)
InjuriesJohn Jones of Llanidloes, newly started at the colliery, was seriously injured.

What happened

On 18 May 1874, two sinkers -- Lumley Ellis of Aberystwyth and William Davies of Llandinam -- were killed roughly 160 yards below the surface when they ignited blowers of gas while sinking a new shaft at Bwllfa Dare Colliery. The explosion was powerful enough to destroy the surface headframe and associated framework, and seriously injured John Jones of Llanidloes, who had only just started work at the colliery.
