Stockdale Colliery

Overview

Stockdale Colliery was a tiny drift mine near Thwaite at the head of Swaledale, opened in 1910 and worked by two or three men until 1931. It took the Tan Hill Coal, known locally as the Stockdale Seam, from two levels, and was one of the last coal workings in the Dales.

History

The Durham Mining Museum records the colliery opening in 1910 with two men employed, under Capt. F. H. Lyell, who owned Tan Hill Colliery in the same decade. In the 1920s it belonged to J. G. Reynoldson & Son and in the 1930s to the Lingholme Trust. It never employed more than three: three in 1921 and two, one underground and one on the surface, through the mid and late 1920s. Household coal is recorded in every return from 1921 to 1930, and the coal is said to have sold at 4d per hundredweight. The Northern Mine Research Society says the mine closed in 1931 and was abandoned in April 1932; the plan of the Stockdale seam, abandoned in 1932, reached the National Coal Board's Durham Division catalogue in 1958 under Mining Record Office reference F.42/24.

Geology

The Northern Mine Research Society identifies the seam as the Tan Hill Coal, here called the Stockdale Seam, dipping at 1 in 12 to the north-west. Its section was 19 inches of coal, a 3-inch dirt band, 8½ inches of coal, a 1½-inch dirt band and 15 inches of coal. The Lists of Mines give 'Limestone Series' in 1921 and 'Stockdale' from 1923.

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

Workings
