Although not within the general Fochriw area, the following information is included since the colliery formed part of the Dowlais Iron Company holdings and was included in the General Report on the Dowlais Collieries which was written by Howell R Jones on 5 October 1909.
General
The report starts by advising that the outputs for the colliery during year ending 31 December 1908 were as follows
No 1 Pit 256,616 tons or an average daily output of 862 gross tons
No 2 Pit 195,049 tons or an average daily output of 650 tons
The winding engines were in fair working order except that work was required on the drum of No1 Pit winding drum at a cost of £250.
The main pumping engine was of the Cornish condensing type and in good order.
No1 pit was fitted with steel rail guides with No2 pit being fitted with rope guides.
The Waddle ventilating fan and engine were both working satisfactorily and there also existed a spare set which were occasionally used.
There were two air compressors which supplied power underground for hauling and pumping. One unit was a two stage non-condensing compound compressor by Messrs Walker Brothers and was capable of compressing 5,000 cubic feet of free air per minute at 70 lbs per sq inch and was comparatively new and in regular use. However, it was loaded to its maximum capacity. The other compressor, which was idle, was an old engine made at Dowlais and had been fitted with a compressing cylinder by Messrs Walker Brothers of Wigan and although the engine was in fair condition, it was wasteful and uneconomical and only used if anything went wrong with the new compound unit. The two compressors could not be used together owing to the steam and blast having to be reduced for other equipment operation.
