Polbeth No.11.jpg

Vertical shaft(s) 402ft to Houston Coal, 660ft to Broxburn Shale, 777ft to Fells Shale

Serving Addiewell Chemical Works

A long-lived pit, situated in Gavieside Village and sometimes referred to as Gavieside No. 11. At various times Fells Shale, Broxburn Shale and Houston Coal were brought to the surface by one of a number of shafts on this site. The site of one of the worst pit disasters in the history of the industry in which four died (the youngest aged 14) when the cage became disengaged from the slides within the shaft.

Workings in the Fells Shale extended north from No. 11, ultimately joining with Fells Shale workings from Westwood No. 30 Pit. Plans suggest that workings in the Fells Shale also extended to the south and east of No. 11, linking via a cross-cut mine to workings from Polbeth No. 8 Pit and Polbeth No. 10 Pit. Fells Shale workings were abandoned in 1900 (or 1927?).

An area of Houston Coal was worked to the east of No. 11, perhaps the workings at "Polbeth" referred to in abandonment plan 3269/A, dated 1894 / 1901. Sketch plans show an adit near the eastern end of Gavieside Row that might have provided alternative access to these workings.

Plans show a roadway heading south west from No. 11 accessing areas of Broxburn Shale, ultimately linked by a cross cut mine to the workings of Polbeth No. 10 Pit. Seams worked: Houston Coal, Broxburn Shale, Fells Shale.

Mapped by the Ordnance Survey of c.1895 - presumably showing the pit in production, with waste haulage to the bing.

      .......

      On Wednesday forenoon much alarm was created in No. 11 pit, Gavieside, by the water suddenly rushing through from some old workings and flooding the pit, in which there are employed over 300 men. A lad named William Finister was drowned. The old workings of mine, worked by the late West Calder Oil Company, were contiguous to No. 11 pit workings, and being full water, a considerable source of anxiety to the management. For some time back levels for draining purposes have been driven into these workings with an advance bore obtaining indications of the whereabouts of the body water. While men were engaged in working one of these levels on Wednesday the water burst in and carried everything before it, completely submerging the lower workings in very short apace time.

      The pit is fortunately equipped with a more than usual number of outlets, else a large number of lives might have been sacrificed. As it is, several men were injured, and others had very narrow escapes, large number leaving pit with very little clothing on. The pumps are kept busy at worlfc but considerable time must elapse before the water can be taken out of the lower section. The scene of the catastrophe was visited during the course of the afternoon by Mr Robert M'Laren, Her Majesty's Inspector Mines for East of Scotland, and Mr Prentice, mining manager. For some time the greatest alarm prevailed the village, the first reports the event having been greatly exaggerated.

      .......

      Messrs. Scott and Mountain have also in hand for Messrs. Young's Praffin Oil Co., of Glasgow, an electric pumping plant for their No.11 pit at Polbeth. This plant consists of a horizontal engine, driving by bely on to a Tyne dynamo giving an output of 40,000 watts. The dynamo supplies current to two sets of three throw ram pumps, driven by electric motors of 25 effective h.p. each, and delivering 150 and 100 gallons per minute respectively against a head of 270 feet. The first pump is situated at a distnace of 850 yards from the dynamo, and a second pump further down the dip 600 yards away, the total distance between the second pump and the dynamo being 1450 yards.

      .......

      A similar (pumping) unit (to that installed by the Midcalder Oil Company at Oakbank in 1876) was erected at Young's Oil Co.'s No.11 pit, Gavieside, about 1882.
