Two-direction energy-gathering blasting technology and its application

Based on analyzing challenging problems in the jointed rock mass confronting the smooth blasting technology, a new blasting technology, a two-direction energy-gathering blasting technology, is introduced for the jointed rock mass. Then the basic technical principles and advantages of the technology have been dealt with in detail, so have the two design schemes. Finally, two application cases are put forward to demonstrate the application prospect of the technology.
