The history of No. 20 Mine is uncertain; from the numerical sequence it might be imagined that No. 20 opened in the late 1870's, although the 1895 OS map shows only an "old shaft" on the site subsequently developed as the "Slant Mine" .

The mine dipped steeply to the south west, exploiting Fells Shale to the east of West Calder. A cross cut mine appears to have provided access to an area of Fells Shale to the east of Harburn Road. The workings were linked to those of Polbeth No. 8 Pit.
