Sundrum Colliery

Overview

Sundrum, at Coylton east of Ayr, is two workings under one name. The Dalmellington Iron Company's pits were returned from 1894 and closed in 1933. Nineteen years later the National Coal Board sank a new mine on the same ground, which produced from 1953 and shut in 1961 with a workforce that never passed seventy-seven.

History

The Dalmellington Iron Company held Sundrum from at least 1894, when it employed 146 people on manufacturing coal, and after 1931 the pits passed with the rest of the company's holdings to Bairds and Dalmellington Ltd. The returns give 131 in 1896 and a dip to 75 in 1900, then follow a No. 3 pit specifically: 128 in 1905, 118 in 1910, 132 in 1915 and 194 in 1920, working the Ell, Main and Major seams for household and manufacturing coal. The colliery employed 173 in 1923 and 130 in 1933. Historic Environment Scotland records that earlier mine as closed in 1933. The National Coal Board began sinking a new mine at Sundrum in 1952 and it came into production in 1953. It was small: an average workforce of 65 and a peak of 77 in 1958. The 1954 Mines Inspectors' return, giving 13 people on household and steam coal from the Ayr Hard seam, catches it in its first year. It closed in 1961. The pits were served by the Coylton Branch railway, which the Dalmellington Iron Company worked. The deaths recorded here are the ordinary kind, and one of them is a plain lesson in what a moment's carelessness cost. James Clark, a miner of 56, kept an oil bottle beside his explosive canister. On 6 December 1912 he went from his place to refill his small lamp and ignited the three pounds of gunpowder the canister held; it must have been left open since he fired a shot earlier in the day. He was badly burned about the arms and face and died four days later.

Geology

Sundrum worked the Ayrshire coalfield at Coylton. The Dalmellington Iron Company's No. 3 pit returned the Ell, Main and Major seams; the National Coal Board's later mine worked the Ayr Hard.

Geological setting: Sedimentary Beds and Seams (well documented example)

Workings

The earlier working was a group of pits of which the returns follow No. 3 from 1905, with Nos. 3 and 4 named on the railway record. The later National Coal Board working was a single mine sunk from 1952 on the same ground. Both were served by the Coylton Branch, worked by the Dalmellington Iron Company. Shaft depths have not been found in the sources read for this record.

Closure

Historic Environment Scotland records the Dalmellington Iron Company's mine at Sundrum as closed in 1933, and the National Coal Board's later mine on the same ground as closed in 1961.

What remains

No account of the colliery ground as it stands today has been found in the sources read for this record. The Sundrum estate east of Coylton is now partly a holiday park.

Recorded claims

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

• Historic Environment Scotland records a National Coal Board mine at Sundrum with sinking commenced in 1952, production in 1953 and closure in 1961, an average workforce of 65 and a peak of 77 in 1958. It notes separately that there was an earlier mine at Sundrum operated by the Dalmellington Iron Company, and after 1931 by Bairds and Dalmellington Limited, which closed in 1933. ¹
• James Clark, a miner of 56, kept an oil bottle beside his explosive canister. On 6 December 1912 he left his place to replenish his small lamp and ignited the three pounds of gunpowder the canister held, which must have been left open since he fired a shot earlier in the day. He was badly burned about the arms and face and died four days later. ²
