MineArchiveLlanhilleth Colliery fall of coal, 1907
| Date | 8 March 1907 |
|---|---|
| Mine | Llanhilleth Colliery |
| Region | Blaenau Gwent |
| Type | Collapse / Roof Fall |
| Fatalities | 2 (William (George) Morgan, 25 or 28, and his brother Walter Worthy Morgan, 20, colliers.) |
| Context | During active mining (The night shift in the Black Vein at Llanhilleth Colliery, where the Inspector noted falls of coal had grown more frequent since the 1905-06 strike.) |
At about one in the morning of 8 March 1907 a lump of coal seven feet across fell from the face in the Black Vein at Llanhilleth Colliery and killed two brothers, William and Walter Morgan, as they filled a dram. Welsh Coal Mines records that a 'bumper' shook the place; the Inspector found the overhanging coal had been held by a single sprag, totally insufficient, and noted that such falls had become more common at the colliery since the strike.
Cause
A fall of overhanging coal from the face in the Black Vein, supported by only one sprag; Welsh Coal Mines attributes it to a 'bumper' shaking the ground.
Contributing factors
The seam was about 7½ feet thick with 10 inches of clod above, worked on the face slip, and the coal overhung about a yard. The lump that fell had both ends loose and only one sprag against it. The Inspector remarked that accidents of this kind had become frequent since the 1905-06 strike.
Investigation & inquiry
H.M. Inspector Joseph S. Martin described the accident in his 1907 report for the Southern District, judging the single sprag totally insufficient.
