MINING CLASS INSPECTION. ———— A Tour Through Tarenni I Colliery. It is a we Il-eeta bUshcd fact that no amount of book-reading can supply the full knowledge gleaned by practical ex- perience, and this principle has now been accepted as forming an important part of technical instruction, and par- ticularly of mining. The Glamorgall Education Committee has therefore made arrangements for the pupils of the various mining classes to visit col- liories, so that difft-rent methods of coal-getting may be examined under j actual conditions. On Monday last a party consisting j almost entirdy of students from Cly- dach and Gwauucaegurwen, under Mr. J. Henri Da vies, M.E.,F.G.S., county mining lecturer, visited the Tarrcni- i Gleiaion Collieries, Ystalyfera, owned by the South Wales Primrose Coal Co. and made a tour of the red vein worked from the Tarreni pit. The party was met at at office by Mr. John Griffiths, M.E., undermanager, and prior to descending into the mine, well-drawn plans were examined and explanations of various phenomena given by Mr. Davies. It is interesting to note that according to geological evidence the Swansea and Neath Valleys, which now run parallel with the Caledonian Canal in Scotland, at one time ran due South and owing to the movement of a moun- tain in Scotland, the direction of the valleys was changed. It was A this time that the Penine Chain and mo tin-. tains were formed, and at the same time faults, or rolls in the coal measures in South Wales were formed, with the result that it was observed that practically all these faults, of which there are some at the Tarreni, run from north to south ,or parallel with this chain of mountains. The party v.i.s then conducted by Messrs. Beh' Lvddon and Gordon Wil- liams to the Tarreni shaft, which is 429 feel- deep, the pit head being 183 feet above 81';1, level and the bottom 246 feet below."The party was lowered into the mine and proceeded for a ehort distance along a parting at the -end of which, prior to coining to a turning, which led to the mail) 'bully' or deep. a halt was made to examine an electric haulage engine house that was being erected. The engine house, which was of arched brick, was 20 foet high at its highest point, and 21 feet wide. The engine to be accemmo- dated here is to be of 300 horse-power. The party then walked for about a. mile down an incline, and on the way saw three forms of air bridges or cross- ings. It was elicited that 63,000 cubic feet of .air was passing down the 'bully,' or road, at a speed of 800 feet. The levels were visited and the coal- face traversed, where it was found that the coal was got by the long wall system. The length of stalls and other data was also given. It was explained that there was a thickness of 25in. of large coal, above which was Oin. of ooiil of inferior quality, surmounted by clod, 2in. in thickness. The roof was good for a certain thickness, and for Chis reason the bottom was cut to allow of sufficient height. It was also observed that there was a number of treacherous "bells" in the roof. The number eight and nine districts were more especially examined, and Mr. Lvddon observed that there is still two miles to work to the boundary. On coming to the surface, a tour was made of the engine houses. At this col- liery the swam is not allowed to evapo- rate into the atmosphere, but is turned into a container which extracts the oil from the steam, the latter then being treated in a cooling tower and utilised to drh:0. a turbine which works an « lectric dynamo. Another object of in- terest was the boilers, which were automatically fed and cleaned; a man being only necessary to fill the bunkers of coal of a small grade, which is then conveyed to the fires and through as clinker. The whole tour was thoroughly en- joyed, and at the office a hearty vote of thanks to Mr. Lvddon and Mr. Grif- fiths for their assistance, and especial- ly tAt the former for his excellent con- duct of the tour, was passed, Mr. Davies o bserving that he hat! been most ready to answer questions. A" expression of sympathy was also voiced with Mr. T. E. Slater, the manager. together with the hope that he would soon recover from his serious illness.
