Details presents in the paper realize at collaboration the Ministry of Science and Technological Development on project No 17004 R. Serbia. Presented carakterisics clivage in aspect on massif rock research in drillholes B-1k, B-2k, B-3k, B-4k and B-5k. Evaliation of rock stability, in which will be place tunnel axis, took from prospecting Krivelj`s River. Iinvestigations are: structural characteristicsa of rock massif, degree of disintegration, alteration degreee, fracture degreee and physico-mechanical characteri...

Limestone massif "Rgotina Rock" has, from a topographical point of view a remarkable, and from a mining point of view, a favourable position of occurrence. It extends in the form of a limestone reef, with the highest peak in its central part (top of Rgotina Rock). Mining has started in 1961. ”Kop 2”, in 1965. ”Kop 3” and in “Kop 5“ 1969.
