From the organization and state of drilling and blasting works largely depends on the management of stocks of blasted rock mass and rhythmicity of work of quarries. As reported data show, the cost of preparation of rocks for excavation at the quarries of the Polar region is 1.5-2 times higher than at the quarries of the central regions of the country with similar mining conditions. Improvement of technology and organization of drilling and blasting operations at the quarries of the Polar region allowed to significantly increase the provision of excavators with blasted rock mass.
