Modern state and main tasks of improvement of ore stripping and release during development with mass collapse

Abstract
Control figures for the development of the national economy of the USSR for 1959-1965 provides for a further increase in the production of various ores. It suffices to say that by 1965, ore output in the various branches of the mining industry will have increased from 2 to 3 times as much as in 1958. The major part of this increase will be achieved (mainly at new deposits) at the expense of open-pit mining, but the share of underground works remains high - about 40-50%.
