Siston Hill Colliery

The sinking date for Siston Hill Colliery, Siston, Bristol is unknown, but was probably in the late 1790s or early 19th century. There is a surviving accident report dated 1804. This names the colliery owner as a Mrs. Peterson. By 1831 the colliery was under the ownership of Toghill & Company.
The pit was put up for sale in 1889 and the prospectus states that it had four shafts, two of which were sunk to a depth of 570 ft . The winding shaft was 9 ft in diameter, walled throughout and had two separate cages. The winding engine was a Boulton and Watt, had a 4-foot-6-inch stroke and a 12-foot drum, and could lift 700 to 800 tons of coal a day. The pumping engine had two 19-inch cylinders and was in working order. Above ground was a bank high enough for double screens which sorted the coal before it was loaded for transportation. A tunnel was provided at the bottom of the bank to enable timber and other materials to descend into the pit without first being hauled to the top. A 100-foot-high circular chimney stack towered over the colliery.
