Abstract

Запропоновано технологію відбійки обводнених гірських порід на кар'єрах з попереднім зневодненням вибухових свердловин за рахунок створення мікротріщин у донній їх частині за допомогою прострілочних донних зарядів.

Предложена технология отбойки обводненных горных пород на карьерах с предворительным осушением взрывных скважин за счет создания микротрещин в их донной части с помощью прострелочных донных зарядов.

Technology of rock blasting with a preliminary dewatering of blastholes by creating microscopic cracks in the bottom of the holes with the help of springing bottom charges is proposed.
