Louisa Colliery explosion, 1947

Louisa Colliery at South Moor, near Stanley, was eight months into public ownership when it exploded on 22 August 1947, killing twenty-two men. The district where it happened, the 4th North in the Hutton seam, had been sterilised for years by a fire in the seam above and had only been made workable again in 1944 when new seals were built nearer the old fire; the inspector's report notes that no inflammable gas had ever been recorded in the seam before.

Cause

An explosion in the 4th North District of the Hutton seam, a district reopened in 1944 after the sealing of a fire in the Low Main seam thirty feet above; the inspector's report records that there was no previous record of inflammable gas in the seam.

What happened

Louisa Colliery, formerly of the Holmside and South Moor group and by 1947 in the 'C' Group of No. 6 Area of the Northern Division of the National Coal Board, worked the middle Durham seams -- Maudlin, Low Main and Hutton -- at South Moor near Stanley. Three downcast shafts served it, Louisa, William and Morrison North, and it employed 1,480 people underground and 350 on the surface for an average daily output of 1,450 tons. Open lights had been used in all the seams down to the Hutton until 1941, when the Chief Mining Engineer decided to put safety lamps throughout the Louisa Old and William sections; the divisional inspector had pointed out that men were hiding matches and other contraband on a main intake haulage road serving a safety-lamp section, and that a serious fire in the Low Main seam in 1929 had been caused by an acetylene lamp. The 4th North District, where the explosion happened, lay within half a mile of the Morrison North shaft; it had been in the open-light area but was placed under the Louisa undermanager and worked with safety lamps to meet the men's wish to belong to the Louisa lodge. The district was a small area of Hutton seam that the 1929 fire had sterilised, about a hundred acres of the seam above having been sealed off; it became workable again when the fire area was entered in 1944 and new seals were built closer to the old fire.

Rescue & recovery

Investigation & inquiry

HM Inspectors of Mines reported on the explosion. The report describes the colliery, the many changes among its principal officials in the first eight months of public ownership -- William Welsh as No. 6 Area general manager, G. H. Braithwaite as agent for the 'C' Group, J. F. Meek as manager of Louisa -- the history of lighting in the seams and the reopening of the 4th North District in 1944.

Recorded claims

Individual factual claims, each attached to the source(s) that support it below. Where sources disagree, both are kept.

• Louisa Colliery, at South Moor near Stanley, was served by three downcast shafts -- Louisa, William and Morrison North -- and employed 1,480 people underground and 350 on the surface for an average daily output of 1,450 tons. ¹
• Open lights were used in all the seams down to and including the Hutton until 1941, when safety lamps were installed throughout the Louisa Old and William sections after the divisional inspector drew attention to men hiding matches on a main intake road and to a serious fire caused by an acetylene lamp in the Low Main seam in 1929. ¹
• The 4th North District was a small area of the Hutton seam sterilised by the 1929 fire in the Low Main seam thirty feet above, which had required about a hundred acres of that seam to be sealed off; the fire area was entered in 1944 and new seals built nearer the old fire, making the Hutton area workable. ¹
• There is no record of inflammable gas having been found in the Hutton seam at this colliery before the explosion. ¹
