Provision of iron ore raw materials for ferrous metallurgy in the next five-year period is envisaged mainly through further development of open-pit mining. The greatest importance will have quarries, developing the deep part of large deposits, which by 1980 will account for about 75% of the total volume of rock mass, developed by the open method, and 85-90% of this volume will be represented by rocks. ...
Currently, only two large deposits of the Turgai ore belt - Sokolovskoye and Sarbaiskoye - are being developed. However, the development of Kacharskoye, Lomonosovskoye, Kurzhunkulskoye and other new deposits is envisaged in the coming years. Due to the similar geological and structural conditions of the deposits of this group, the patterns of changes in the engineering and geological conditions of the development of Sokolovskoye and Sarbaiskoye deposits can be used in the design of new mining enterprises. ...
