Abstract

This invention relates to a method for breaking and heaving rock using blastholes modified in their diameter combined with a multiple sequential blasting method. The method includes drilling at least one blasthole having a distal end with a diameter less than the diameter of its proximal end into a rock to be broken and heaved, charging the distal end with a detonator, initiators and explosive charge, inserting the barrier plug, and subsequently charging the proximal end with a detonator, initiators and explosive charge, and then initiating and detonating the charges in a proximal to distal sequence to break and heave the rock.
