ABSTRACT/Full article available only in Bulgarian language/

The "Propast - Dobrovolec" Mine produces bentonite clay by open pit mine
technology. This report presents mining and geology characteristic of the field. Here
are given the results from the determination of the physical and mechanical indexes
of clay and rocks. The slope angles of the benches are determined by the combined
schemes of V. Felenius, and for the general pit edged angles are used
Prof.Fisenko’s methods (VNIMI - Sankt Peterburg).
