Open questions: West Midlands

Where sources disagree, MineArchive keeps both accounts rather than picking one; where a fact could not be settled, the record says so. 12 such claims on 10 records. All regions.

Beech Tree Colliery

• Local tradition held that a manager from a neighbouring colliery bribed the Beech Tree nightwatchman for underground access, discovered a good coal seam running in one direction, and his own company then bought up the mineral rights on that side — presented in the source as contemporary rumour, not an established fact. (uncertain)

Brettell Lane Colliery

• The BGS mine-plans catalogue holds a Mining Remediation Authority abandonment plan titled 'Brettell Lane' (catalogue WM545, Fireclay Thick Brooch Ironstone Ten Feet, dated 1912); 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)

Foxyards Colliery

• The official 1880 List of Mines entry for this pit reads "Foxyards, Tipton, W. Punter", while the same return is the basis for Grace’s Guide listing Foxyards twice among the Earl of Dudley’s collieries. The two have not been reconciled. (disputed)

Great Bridge Colliery

• The report for 1853 gives fifteen dead; the Mining Almanack for 1850 twenty-five dead and forty-three injured. (disputed)

New Hawne Colliery

• The BGS mine-plans catalogue holds a Mining Remediation Authority abandonment plan titled 'Hawne' (catalogue 11705, Thick, dated 1897); 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)

Park Lime Pits

• Stone from the quarries may have been used by the Romans for paving on Watling Street to the north of the site, though the suggestion is not established. (uncertain)

Rounds Green New Pit

• The company working the pit in 1846 was Messrs Parker. (disputed)

Wednesbury Oak Colliery

• The BGS mine-plans catalogue holds a Mining Remediation Authority abandonment plan titled 'Wednesbury Oak' (catalogue 17274, Thick Coal, dated 1877); 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)

Windmill End Colliery

• The engine house and plant closed in 1925 after a lengthy series of miners' strikes. (disputed)
• The engine ceased work in 1928, having become the last colliery pumping engine operating in the area after the flooding of 1919–20. (disputed)
• Windmill End Colliery's No. 3 pit was sunk in 1830 beside the Dudley Canal Line No. 2, most likely by the Earl of Dudley's mining department. (uncertain)

Wyken Colliery

• The BGS mine-plans catalogue holds a Mining Remediation Authority abandonment plan titled 'Wyken' (catalogue EM1127, Rider (Two Yard & Ryder), dated 1880); 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.
