This paper will cover blasting techniques that are applicable to underground and other rescue that involves removing obstacles and breaking rock in close proximity to rescuers and subjects.
Underground Blasting, Blasting Induced Fumes, Entrapped Fumes, Ventilation, Mine Re-entry/ Dilution Time, Safety, Efficiency
In order to achieve anti-terrorism, production safety, better explosive performance, lower cost, and environment protection, we developed HMS (emulsification in borehole).
Very little studies have investigated the behavior of cracks in unlined tunnels over long periods of time, especially when such flaws are subjected to blast-induced vibrations. Using a pool of 30+ blast events, a positive correlation was found between the peak particle velocity and peak crack movement.
