Open questions: South Lanarkshire

Where sources disagree, MineArchive keeps both accounts rather than picking one; where a fact could not be settled, the record says so. 40 such claims on 22 records. All regions.

Auchenbegg Colliery

• The first deep mine at Auchenbegg operated in 1837. (disputed)
• Deep mining at Auchenbegg lasted almost 200 years. (disputed)

Auchlochan Colliery

• Hugh S. Dunn operated Auchlochan from 1893 to 1902, before W.C.S./C.S. Cunningham; a specialist railway-history source sequences Dunn then Cunningham then Caprington & Auchlochan Collieries without giving Cunningham's own start year precisely, which is not fully reconciled against this record's existing 1890-1900 Cunningham dates. (disputed)
• Caprington & Auchlochan Collieries Ltd removed the pumps from Auchlochan's lower levels in June 1931 as uneconomical, went into liquidation in 1932, and was carried on by liquidator A.S. Macharg with mining agent David Todd -- reports vary on the workforce during this period, between around 400 (normally employed at the pits) and around 800 (across the wider Coalburn district) -- before William Dixon Ltd bought the Auchlochan pits in 1934. (disputed)
• Auchlochan employed around 500 men at its 1968 closure, per a local-history account. (uncertain)

Avonbraes Colliery

• Avonbraes mine opened in 1940 and was worked until 1969. (disputed)

Bankend Colliery

• A record from 1890 names the 'Owners of Chapelhall Colliery' as proprietors of a Bankend No.11 Colliery. (uncertain)

Bellfield Colliery

• The pit flooded after a dispute over pumping arrangements. (disputed)
• The pit flooded because no maintenance was done during the strike. (disputed)

Blantyreferme Colliery

• The BGS mine-plans catalogue holds a Mining Remediation Authority abandonment plan titled 'Blantyreferme' (catalogue S430, Virgin, dated 1947); the catalogue gives no location and the plan's details do not clearly tie it to this working, so it may belong to another of the same name. (uncertain)

Bothwell Castle Colliery

• Canmore gives the Nos. 1 and 2 pits as closed in 1950 and abandoned in 1953, while the Durham Mining Museum still lists the Nos. 3 and 4 pits, with 115 men working the Humph seam, in 1954; the record's 1959 end of coal working comes from the Blantyre Project's history. (disputed)
• The Northern Mine Research Society dates the shaft accident that killed five men descending No. 2 pit to 28 June 1889, citing the Mines Inspector's report for that year; the Durham Mining Museum lists a five-death disaster at the colliery on 28 June 1899. (disputed)

Canderrigg Colliery

• Canderrigg Nos. 4 and 5 closed in January 1954. (disputed)
• Owned by John McLean in the 1950s, the pit closed in September 1958. (disputed)

Coatspark Colliery

• Coatspark Colliery, Flemington Coal Company, was sunk in 1937 and closed in 1958. (disputed)
• Coatspark, Cambuslang, is dated 1925 to May 1958. (disputed)

Cornsilloch Colliery

• Cornsilloch Colliery worked coal and fireclay from about 1894 to 1937. (disputed)
• Its Ell workings were abandoned in 1944. (disputed)

Dechmont Colliery

• Dechmont Pit worked from 1890 to 1930. (disputed)

Dykehead Colliery

• In 1861 the colliery belonged to the Summerlee Iron Company. (disputed)
• In 1861 the colliery belonged to Wilsons and Company. (disputed)

Earnock Colliery

• The BGS mine-plans catalogue holds a Mining Remediation Authority abandonment plan titled 'Earnock' (catalogue 13228, Ell, dated 1942); the catalogue gives no location and the plan's details do not clearly tie it to this working, so it may belong to another of the same name. (uncertain)

Home Farm Colliery, Hamilton

• The museum gives 1870 to 1925; Moore's 1877 report says worked for about ten years and The Times said since 1864. (disputed)

Kennox Colliery

• Kennox Colliery closed in 1972, its coal reserves exhausted, having passed to the National Coal Board on nationalisation in 1947. (disputed)
• The national record of the site gives sinking or production from about 1908 and closure in 1964. (disputed)
• The colliery opened in 1908 and closed in June 1972, owned by the Kennox Colliery Co. Ltd from 1910 to 1946 and the National Coal Board from 1947 to 1972. (disputed)

Leadhills

• One account states the last shaft at Leadhills closed in 1938; another describes mining across the wider Leadhills–Wanlockhead district continuing, on a reduced basis, into the 1950s. (disputed)
• A mining disaster in 1817 killed seven miners from noxious fumes; some accounts note ambiguity over whether the rescue attempt itself contributed to the death toll. (uncertain)
• Gold mined at Leadhills between 1538 and 1542 was reportedly used to make crowns presented to James V and his queen, valued at the time at around £100,000. (uncertain)

Newton Colliery, Cambuslang

• Newton had closed by the early 1900s. (disputed)

Quarter Colliery

• Buddlepit, drawing on the Northern Mine Research Society, records the colliery as worked from 1873 to 1930. This cannot be the whole story, since the fatal explosion here was in 1841 and Groome describes the village and its ironworks in 1884. (disputed)
• The BGS mine-plans catalogue holds a Mining Remediation Authority abandonment plan titled 'Quarter' (catalogue 5586, Bannockburn Main, dated 1910); the catalogue gives no location and the plan's details do not clearly tie it to this working, so it may belong to another of the same name. (uncertain)

Tarbrax Oil Shale Mine

• Fatal accidents at Tarbrax over the years are recorded as resulting from falling shale, runaway hutches, explosions and falls from retort platforms, though no single incident is documented in enough detail to stand as its own disaster record. (uncertain)

Thinacres Mine

• Thinacres Mine, Overwood Coal Company, began production in 1939 and closed in 1963. (disputed)
• Thinacres, Larkhall, is dated 1938 to May 1963. (disputed)
• The Knowetop and Thinacre mines were nationalised in 1947. (disputed)
• Thinacres was transferred to the National Coal Board in 1949. (disputed)

Udston Colliery

• The BGS mine-plans catalogue holds a Mining Remediation Authority abandonment plan titled 'Udston' (catalogue 6814, Humph, dated 1934); the catalogue gives no location and the plan's details do not clearly tie it to this working, so it may belong to another of the same name. (uncertain)

Waterland Colliery

• A 1915 newspaper report on a new colliery shaft being sunk nearby recalls an older 'Waterlands Pit' on the opposite side of the road, worked some forty years earlier (around 1875) and owned by Loudon and Miller -- the same partnership behind the neighbouring East Law Colliery. (uncertain)
• Thomas Hamilton, a brick and tile manufacturer based at Park House, Carstairs, is documented working a brickfield at 'Waterlands by Carluke' from at least 1861, alongside other works at Auchengray, Pool, Carmichael and Braidwood -- the same Hamilton family name the 1880 return gives for the colliery, though the two businesses are not confirmed as the same concern.
