A method for blasting operations at open-pit development of ore deposits includes determination of boundaries of blast blocks, drilling wells, charging those with explosive. Then switching of blast network is performed, with sequential blasting blast blocks with given delay interval. After blasting the first blast block with given time interval blasting of following blast blocks is performed.
