8 Crælius, Per Anton
SUBJECT AREA: Mining and extraction technology[br]b. 2 November 1854 Stockholm, Swedend. 7 August 1905 Stockholm, Sweden[br]Swedish mining engineer, inventor of the core drilling technique for prospecting purposes.[br]Having completed his studies at the Technological Institute in Stockholm and the Mining School at Falun, Crælius was awarded a grant by the Swedish Jernkontoret and in 1879 he travelled to Germany, France and Belgium in order to study technological aspects of the mining, iron and steel industries. In the same year he went to the United States, where he worked with an iron works in Colorado and a mining company in Nevada. In 1884, having returned to Sweden, he obtained an appointment in the Norberg mines; two years later, he took up employment at the Ängelsberg oilmill.His mining experience had shown him the demand for a reliable, handy and cheap method of drilling, particularly for prospecting purposes. He had become acquainted with modern drilling methods in America, possibly including Albert Fauck's drilling jar. In 1886, Crælius designed his first small-diameter drill, which was assembled in one unit. Its rotating boring rod, smooth on the outside, was fixed inside a hollow mandrel which could be turned in any direction. This first drill was hand-driven, but the hydraulic version of it became the prototype for all near-surface prospecting drills in use worldwide in the late twentieth century.Between 1890 and 1900 Crælius was managing director of the Morgårdshammar mechanical workshops, where he was able to continue the development of his drilling apparatus. He successfully applied diesel engines in the 1890s, and in 1895 he added diamond crowns to the drill. The commercial exploitation of the invention was carried out by Svenska Diamantbergborrings AB, of which Crælius was a director from its establishment in 1886.[br]Further ReadingG.Glockemeier, 1913, Diamantbohrungen für Schürf-und Aufschlußarbeiten über und unter Tage, Berlin (examines the technological aspects of Crælius's drilling method).A.Nachmanson and K.Sundberg, 1936, Svenska Diamantbergborrings Aktiebolaget 1886–1936, Uppsala (outlines extensively the merits of Crælius's invention).See also: Fauvelle, Pierre-PascalWK -

20 Kegel, Karl
SUBJECT AREA: Mining and extraction technology[br]b. 19 May 1876 Magdeburg, Germanyd. 5 March 1959 Freiberg, Saxony, Germany[br]German professor of mining who established the mining of lignite as a discipline in the science of mining.[br]Within the long tradition of celebrated teachers at the Mining Academy in Freiberg, Kegel can be considered as probably the last professor teaching the science of mining who was able to cover all the different disciplines. As was the case with a number of his predecessors, he was able to combine theoretical research work with the teaching of students and to support his theories with the practical experience of industry. He has apprenticed at the Mansfeld copper mines, went to the School of Mines at Eisleben (1896–8), worked as an engineer with various mining companies and thereafter became a scholar of the Berlin Mining Academy (1901–4). For twelve years he taught at the Bochum School of Mining until, in 1918, he was appointed Professor of Mining at Freiberg. There, one year later, as a new approach, he introduced lectures on brown-coal mining and mineral economics. He remained Professor at Freiberg until his first retirement in 1941, although he was active again between 1945 and 1951.In 1924 Kegel took over a department at the State Research Institute for Brown Coal in Freiberg which he extended into the Institute for Briquetting. In this field his main achievement lies in the initially questioned theory that producing briquettes from lignite is a molecular process rather than the result of bituminous factors. This perception, among others, led Rammler to produce coke from lignite in 1951. Kegel's merits result from having established all the aspects of mining and using lignite as an independent subdiscipline of mining science, based on substantial theories and an innovative understanding of applied technologies.[br]Bibliography1912, Bergmännische Wasserwirtschaft, Halle (Saale). 1931, Lehrbuch der Bergwirtschaft, Berlin.1941, Bergmännische Gebirgsmechanik, Halle (Saale). 1948, Brikettierung der Braunkohle, Halle (Saale).1953, Lehrbuch des Braunkohlentagebaus, Halle (Saale).Further ReadingE.Kroker, "Karl Kegel", Neue deutsche Biographie, Vol. XI, p. 394 (a reliable short account).Bergakademie Freiberg (ed.), 1976, Karl Kegel 1876–1959.
