The Technology of Opening and Mining Sites of Complex Occurrence of Placer Deposits in Permafrost Conditions
Abstract The article presents technical solutions for the opening and development of sites of the placer deposits with upper «hanging blocks» in the conditions of the «Obryv-Razvalisty-Promezhutochnyj» placer deposit. According to the experience of the opening workings in placer deposits of the Nort...
