Abstract:

The study is designed to improve the technology of the application of explosives to rapid excavation, particularly tunneling and mining in hard rock. Primary areas of research include development of jelled or slurry type explosives suitable for automatic injection into boreholes and feasibility studies of initiation systems alternative to conventional electric blasting caps for detomating these explosives.
