SUBJECT AREA: Mining and extraction technology[br]b. 29 November 1822 Gosselies, Belgiumd. 16 January 1905 Auderghem, Belgium[br]Belgian mining engineer, pioneer in boring shafts.[br]In 1842, as a graduate of the Ecole des Mines in Liège, he became a member of the Belgian Corps Royal des Mines, which he left ten years later as Chief Engineer. By that time he had become decisively influential in the Société Anglo-Belge des Mines du Rhin, founded in 1848. After it became the Gelsenkirchen-based Bergwerkgesellschaft Dahlbusch in 1873, he became President of its Board of Directors and remained in this position until his death. Thanks to his outstanding technical and financial abilities, the company developed into one of the largest in the Ruhr coal district.When K.G. Kind practised his shaft-boring for the company in the early 1850s but did not overcome the difficulty of making the bottom of the bore-hole watertight, Chaudron joined forces with him to solve the problem and constructed a rotary heading which was made watertight with a box stuffed with moss; rings of iron tubing were placed on this as the sinking progressed, effectively blocking off the aquiferous strata as a result of the hydrostatic pressure which helped support the weight of the tubing until it was secured permanently. The Kind-Chaudron system of boring shafts in the full section marked an important advance upon existing methods, and was completely applied for the first time at a coalmine near Mons, Belgium, in 1854–6. In Brussels Chaudron and Kind founded the Société de Fonçage par le Procédé Kind et Chaudron in 1854, and Chaudron was granted a patent the next year. Foreign patents followed and the Kind-Chaudron system was the one most frequently applied in the latter part of the nineteenth century. Altogether, under Chaudron's control, there were more than eighty shafts sunk in wet strata in Germany, Belgium, France and England.[br]Bibliography1853–4, "Notice sur le procédé inventé par l'ingénieur Kind, pour l"établissement des puits de mines', Annales des travaux publics de Belgique 12:327–38.1862, "Über die nach dem Kindschen Erdbohrverfahren in Belgien ausgefùhrten Schachtbohrarbeiten", Berg-und Hüttenmännische Zeitschrift 21:402−7, 419−21, 444−7.1867, "Notice sur les travaux exécutés en France, en Belgique et en Westphalie de 1862– 1867", Annales des travaux publics de Belgique 25: 136–45.1872, "Remplacement d'un cuvelage en bois par un cuvelage en fonte", Annales destravaux publics de Belgique 30:77–91.Further ReadingD.Hoffmann, 1962, Acht Jahrzehnte Gefrierverfahren nachPötsch, Essen, pp. 12–18 (evaluates the Kind-Chaudron system as a new era).W.Kesten, 1952, Geschichte der Bergwerksgesellschaft Dahlbusch, Essen (gives a delineation of the mining company's flourishing as well as the technical measures under his influence).T.Tecklenburg, 1914, Handbuch der Tiefbohrkunde, 2nd edn, Vol VI, Berlin, pp. 39–58 (provides a detailed description of Chaudron's tubing).WK -
7 Kind, Karl Gotthelf
SUBJECT AREA: Mining and extraction technology[br]b. 6 June 1801 Linda, near Freiberg, Germanyd. 9 March 1873 Saarbrücken, Germany[br]German engineer, pioneer in deep drilling.[br]The son of an ore miner in Saxony, Kind was engaged in his father's profession for some years before he joined Glenck's drillings for salt at Stotternheim, Thuringia. There in 1835, after trying for five years, he self-reliantly put down a 340 m (1,100 ft) deep well; his success lay in his use of fish joints of a similar construction to those used shortly before by von Oeynhausen in Westphalia. In order to improve their operational possibilities in aquiferous wells, in 1842 he developed his own free-fall device between the rod and the drill, which enabled the chisel to reach the bottom of the hole without hindrance. His invention was patented in France. Four years later, at Mondorf, Luxembourg, he put down a 736 m (2,415 ft) deep borehole, the deepest in the world at that time.Kind contributed further considerable improvements to deep drilling and was the first successfully to replace iron rods with wooden ones, on account of their buoyancy in water. The main reasons for his international reputation were his attempts to bore out shafts, which he carried out for the first time in the region of Forbach, France, in 1848. Three years later he was engaged in the Ruhr area by a Belgian-and English-financed mining company, later the Dahlbusch mining company in Gelsenkirchen, to drill a hole that was later enlarged to 4.4 m (14 1/2 ft) and made watertight by lining. Although he had already taken out a patent for boring and lining shafts in 1849 in Belgium, his wooden support did not qualify. It was the Belgian engineer Joseph Chaudron, in charge of the mining company, who overcame the difficulty of making the bottom of the borehole watertight. In 1854 they jointly founded a shaft-sinking company in Brussels which specialized in aquiferous formations and operated internationally.[br]Principal Honours and DistinctionsChevalier de la Légion d'honneur 1849.Bibliography1842, Anleitung zum Abteufen von Bohrlöchern, Luxembourg.Further ReadingH.G.Conrad, "Carl Gotthelf Kind", Neue deutsche Biographie 10:613–14.D.Hoffmann, 1959, 150 Jahre Tiefbohrungen in Deutschland, Vienna and Hamburg, pp. 20–5 (assesses his technological achievements).T.Tecklenburg, 1914, Handbuch der Tiefbohrkunde, 2nd end, Vol. VI, Berlin, pp. 36–9 (provides a detailed description of his equipment).J.Chaudron, 1862, "Über die nach dem Kindschen Erdbohrverfahren in Belgien ausgeführten Schachtbohrarbeiten", Berg-und Hüttenmännische Zeitung 21:402–4, (describes his contribution to making Kind's shafts watertight).WK -
8 Wolf, Carl
SUBJECT AREA: Mining and extraction technology[br]b. 23 December 1838 Zwickau, Saxony, Germanyd. 30 January 1915 Zwickau, Saxony, Germany[br]German inventor of the most popular petroleum spirit safety lamp for use in mines.[br]From an old mining family in the Saxon coalfields, Wolf was aware from his youth of the urgent demand for a miner's lamp which would provide adequate light but not provoke firedamp explosions. While working as an engineer in Zwickau, Wolf spent his spare time conducting experiments for such a lamp. The basic concept of his invention was the principle that dangerous concentrations of methane and air would not explode within a small pipe; this had been established almost seventy years earlier by the English chemist Humphrey Davy. By combining and developing certain devices designed by earlier inventors, in 1883 Wolf produced a prototype with a glass cylinder, a primer fixed inside the lamp and a magnetic lock. Until the successful application of electric light, Wolfs invention was the safest and most popular mining safety lamp. Many earlier inventions had failed to address all the problems of lighting for mines; Davy's lamp, for example, would too quickly become sooty and hot. As Wolfs lamp burned petroleum spirit, at first it was mistrusted outside Saxony, but it successfully passed the safety tests in all the leading coal-producing countries at that time. As well as casting a safe, constant light, the appearance of the cap flame could indicate the concentration of fire-damp in the air, thus providing an additional safety measure. Wolfs first patent was soon followed by many others in several countries, and underwent many developments. In 1884 Heinrich Friemann, a merchant from Eisleben, invested capital in the new company of Friemann and Wolf, which became the leading producer of miners' safety lamps. By 1914 they had manufactured over one million lamps, and the company had branches in major mining districts worldwide.[br]Further ReadingF.Schwarz, 1914, Entwickelung und gegenwär-tiger Stand der Grubenbeleuchtung beim Steinkohlen-Bergbau, Gelsenkirchen (a systematic historical outline of safety lamp designs).WK
