February 4, 1916. THE COLLIERY GUARDIAN. 233 Notts and Derbyshire. Mr. Frank Hall, general secretary of the Derbyshire Miners’ Association, has been appointed a magistrate for the borough of Chesterfield. The Midlands. Monthly Drainage Commission Report — Application of Electricity to Coal Mining. The heavy rainfall of December has resulted in a consider- able increase in the pumping of the South Staffordshire Mines Drainage Commission. The engineers’ reports, presented at the monthly meeting of the Commission at Dudley on Wednesday, showed that the rainfall for the last four weeks had been 1-85 in. The general manager and engineer for the Tipton district (Mr. E. Howl) stated that the pumping had been 10,701,600 gals, per 24 hours, as compared with 9,823,900 gals, last month, and 10,506,000 gals, in the corresponding period last year, or an increase of 880,000 gals, per 24 hours compared with last month, and '200,000 gals, compared with a year ago. With regard to the Moat pound, the water was still held up at the Tibbington by-pit of the Empire Colliery, and it had not been necessary to work the Moat old engine or Gospel Oak Mond gas-driven plant more than a few turns. At Bradley the water had increased considerably. The engine was at present working at one stroke per minute less than full speed. At Decpfields it was now necessary to work the new engine at full speed, compared with three-quarter speed a month ago. The Park Lane Mond gas-driven print was now working at full speed, and was sinking the water very slowly. There was little change at the other engines. , The underground level men had been engaged in repairs to Park Lane engine shaft, and in cleansing bottom level of the Moat engine. — The surface drainage engineer (Mr. S. B. Priest) reported that pulsometers for surface drainage had been fixed at Blakeley Wood and Park Lane. The raising of the Boggv Arm course, where swagged by mining on down- stream side of Gospel Oak, had been continued during the month, and some cleansing had been done on Elwell Street, Denbigh, and Cop Hall courses. The repairing of mining damage on Shavers End and Old Dock courses had also been continued, while the puddle of basin at Windmill End engine wharf had been raised. A piped course for surface drainage was being laid at No. 26 Salt wells.—The engineer for the Old Hill district (Mr. W. B. Collis) reported that owing to the winter rains, the water at the Windmill End pumping engine had increased from L.f to 54 strokes per minute during the past month, but it had not required the assistance of the Buffer? pumping engine. The Buffer? level was in good order, while the Saltwells and Waterfall Lane pounds stood at their usual level. An interesting lecture was given to the members of the Wolverhampton and District Engineering Society last week by Mr. C. Jones. A.M.I.E.E., chief electrical engineer, Cannock Chase Collieries, and vice-president of the Warwick and Staffordshire branch of the Association of Miming Electrical Engineers, on the question of the application of electricity to the mining industry. In his preliminary remarks, the lecturer traced the history of fits introduction for shot firing, signalling, and lighting. Pie dealt chiefly with its application for power purposes, such as winding,-hauling, ventilating, coal cutting, and pumping, and showed how by its adoption great economies had been secured, in some cases even to the extent of making the working profitable, whereas by any other methods the working costs would have been so excessive that the pit would have had to be closed down. The relative advantages of electricity, steam, and com- pressed air for the transmission of power were dealt wTith, and this led to for confirmation or otherwise at the next meeting of the lodge, it is understood that tho proposal takes immediate effect.
