UNDERGROUND BAUXITE EXPLOITATION IN THE WESTERN DINARIDS ESSENTIAL FACTS AND COMMENTS

After a short information about the causes both for the deficiency of papers on bauxite underground mines and for the development of such mines, a concise sketch of the geologic structures of the bauxite regions in the Western Dinarids, inclusive the chemical composition of the bauxites, is given. The main portion of the paper is devoted to the description of the following bauxitic regions: Drniš (with the mines Kalun and Kumanovo), Obrovac (Dračevac, Ćukovac—Grižinice and Krš), Mostar (Orašnica, Tribošić, Trobukva, Dabrica), Jajce (Poljane, Crvene Stijene), Bosanska Krupa (Risovac), and Sinj (Visoka). Presented are the »bauxitic« history of the region as well as its mining characteristics, from the mode of opening to the used mining methods, with their adventages and disadvantages. Comments are made, but no conclusions drawn; the future remains open
