| Abstract | The technique of displacement of rocks with different hardness during explosions, has been developed by authors and recommended for usage in “Tashkura” quarry at NMMC. Comparison of conventional and new technology in parameters of expenses on drilling, explosion, excavation and transportation of mining rocks has been shown that total described electric consumptions on explosion displacement of overburden rocks to inside dump lower, than during usage automobile transport delivery. |
