Tylecoch Colliery explosion, 1868

An explosion of firedamp at Tylacoch (Tylecoch) Colliery, Treorchy, on 23 January 1868 killed three colliers and injured several others among the twenty men underground. The inspector's report led to the owner's prosecution for working with a single shaft and allowing unlocked lamps.

Context During active mining

Cause

Firedamp from a blower about eleven yards back from the face, fired at Thomas Butler's stall; the inquest heard that Butler had taken the top off his lamp.

Contributing factors

The blower had run for three months and the roadway it came from had only been stopped off. Men lit their pipes by drawing the flame through the gauze of their lamps. An air door that may have been left open could have let the gas reach the face. The pit had a single shaft although the Nine Feet seam had recently been won and more than twenty men worked in it.

What happened

The collier Richard Davies told the inquiry that he had never seen gas fired at the blower and believed it safe while the air doors were shut. A thirteen-year-old door boy, Thomas Mart, had passed through the door between Butler's and Howell's stalls with the haulier James Price minutes before the explosion; he believed Price had closed it behind the drams, but could not say so for certain.

Investigation & inquiry

The coroner, Mr. Overton, opened the inquest at the Cardiff Arms Hotel, Treorchy, on 24 January and adjourned it more than once so that the district inspector, T. E. Wales, could give evidence. Wales's report to the Home Office found grave breaches of the mining statutes.

Legal & regulatory aftermath

At Pontypridd in April 1868 the owner, Thomas Jones of Cardiff, was prosecuted on two summonses: under the 1862 Act for working more than twenty men in a seam with one shaft, after Wales had twice warned him by letter, and under the 1860 Act for allowing lamps to be used unlocked. He admitted the first and was fined £5 and costs on each.
