Status Researched

At ten past one in the morning of 10 December 1895 the Emerald Pit in the townland of Congo flooded catastrophically and six men were killed. The colliery's head engineer had warned that old water-filled shafts lay nearby and that breaching one would be disastrous. That is exactly what happened.

Cause

An inrush from old, abandoned water-filled shafts into the narrow coal seam the men were working.

Contributing factors

The head engineer at the colliery had raised concerns about the safety of the mine beforehand, warning specifically that there would be old shafts filled with water and that breaching one accidentally would be disastrous.

What happened

The Emerald Pit at Congo was working a narrow seam when, at ten past one on the morning of 10 December 1895, huge volumes of water broke in and drowned the six men at the face. What makes it a hard story is that it had been foreseen: the colliery's own head engineer had warned that the ground held old shafts standing full of water, and that accidentally breaching one would be catastrophic. Four of the six were Englishmen who had come over for the work — two from Ashton-under-Lyne who were uncle and nephew, another from Ashton and one from Manchester.

Rescue & recovery

A relief fund was set up for the families and £940 raised to be shared among the relatives.

Investigation & inquiry

No formal inquiry report has been located in this pass; the account rests on the coalfield's own documented history.

Memorials & commemoration

The Congo Pit was shut down in 1900, five years after the disaster.
