All of the compressed air requirements for both mines were normally served by an electric compressor sited at the No. 2 mine. However the cold weather had damaged this, and portable diesel compressors were on hire. The air was delivered to the workings through steel pipes, at a working pressure of 550 KN/m3.
Prior to the commencement of work on this level at 1018 feet A.O.D. during January 1931 by Guest, Keen and Nettlefolds, a trial pit was sunk at about 100 feet in elevation above the level entrance to test for the Tyla Du No3 seam. The shaft was 91 feet 5 inches deep, the top of which was 1136feet A.O.D. The last working is dated 21 February 1931 on Abandonment Plan No 10579 .
Work on this level commenced on 27 December 1923 at 1057 feet A.O.D. By the Dowlais Iron Company and was still working on 1 October 1931 when surveyed by Sydney Vaughan, Agent. It was located about 100 yards from the river on the eastern side of the valley almost opposite Carmel Chapel which was situated on the western side of the valley.. The average composition of the seam was a top clod layer of one foot on top of two foot Coal Authority Plan No SWR 3205 gives details of the No1 Level (Brithdir Seam) new workings up to 22 November 1985. The earliest dates being recorded on the worKings being May 1982 and the latest 22 November 1985.However, it is also listed from 1967
The co-ordinates of the mouth of No1 level being given as E.309510 N 204202.two and a half inches of coal. Abandonment Plan Number 10580 refers.
This again was an old DIC level and was worked by the Llewellyns during the 1960/70’s. The coal seam worked was locally known as the “upside-down seam” since it comprised, from the top down, 2ft 2 inches of muck, 1 ft of coal, 6 inches of muck, fireclay with a shiny hard bottom which was the reverse composition of all other local coal seams.
This was not worked for long since the composition of the seam did not improve.
