Technological calculations and designs of openwork of deposit of anticlinal, synclinal form and layer high-dipping deposit are executed. Classification of basic flowsheets of openwork of deposits of ferrous quartzites and extension basic progress trends of saving resources and ecological technologies of openwork is carried out. Developed saving resources and opening of quarries ecological to technology with the difficult mining-and-geological terms of development taking into account the geological structure and morphology of productive layers of iron-ore deposits. The method of determination of optimum parameters of placing of semioportable shifting points to the working area of quarry is developed. Parameters are rounded saving resources flowsheets of the opened mountain works with the frequent moving of internal and external dumps. It is developed and grounded saving resources technology of without preservation temporally non-working sides from by the use of dragline Product Description popup.authors popup.nrat_date 2020-04-02 Close
