STUDYING THE MAIN CRACKS SYSTEMS INFLUENCE IN ROCK MASS OF THE "EVRAZ KGOK" NORTHERN OPEN PIT ON THE QUALITY OF BLASTED ROCK MASS CRUSHING
The article presents the results of geotechnical studies of the North pit of "EVRAZ KGOK". The study of both rock mass structural-tectonic structure and parameters of position the main systems of cracks allowed pit field zoning according to blocking and identifies the causes of the increased oversize output in a number of rock mass sections. The measures have been developed to improve the quality of blasted rock mass crushing
