Overview
Young's Paraffin Light and Mineral Oil Company's shale pit at Gavieside, West Calder, sunk from 1867 to the Fells Shale at 777 feet to feed the Addiewell works. One of the company's oldest and largest pits, it lost four young miners in 1885 when the cage left its slides, and closed in 1901.
History
No. 11 pit, in the lands of Polbeth and standing in Gavieside village about three-quarters of a mile north-east of West Calder, was sunk from 1867, when the Addiewell Chemical Works advertised for contractors to take it down about 100 fathoms to the shale. It served Young's Addiewell works, and at various times its shafts raised the Houston coal at 402 feet, the Broxburn shale at 660 feet and the Fells shale at 777 feet. Its Fells shale workings ran north to join those of Westwood No. 30 pit.
In 1885 over 200 men and boys worked there, starting the week at one in the morning. On 16 March 1885 the eighth cage of the morning left its slides and dropped some thirty fathoms; four young miners were thrown to the bottom and killed (see Disasters, below). In February 1890 water burst in from the old workings of the West Calder Oil Company, flooding the lower workings of a pit employing over 300; one lad drowned, and its many outlets saved the rest. Electric pumps were installed in 1896.
In April 1901 the hundred men still working No. 11 were told to bring their tools to the surface, as the pit, one of the company's oldest and largest, was to close. The site has returned to farmland, with its bing a wooded mound.
Geology
Oil shale of the West Lothian field: the Broxburn shale at 660 feet and the Fells shale at 777 feet, with the Houston coal at 402 feet.
Workings
A vertical shaft or shafts reaching the Houston coal, Broxburn shale and Fells shale, with a cross-cut mine to the Polbeth No. 10 workings and a link through the Fells shale to Westwood No. 30. A steam pumping unit was put in about 1882 and an electric pumping plant in 1896.
Closure
Notice to close was given in April 1901, when about a hundred men still worked it. The abandonment plan of its Fells shale workings is dated 1900, quoted elsewhere as 1927.
What remains
The site has returned to agriculture; the waste bing remains as a wooded area within farmland.

Redevelopment

Gavieside No. 11 Pit cage accident, 1885
16 March 1885 · Winding / Shaft Accident · 4 fatalities
Between six and seven on the morning of Monday 16 March 1885, the eighth cage lowered into No. 11 Gavieside shale pit at West Calder left its slides less than twenty fathoms down and jammed. The rope kept paying out until the cage broke free and dropped some thirty fathoms; four of the six young miners in it were thrown out and killed at the bottom of the shaft.
