Abstract:

A working prototype triggered barrier system has been designed, built and tested. It has successfully suppressed and extinguished several propagating coal dust explosions in two shock tube facilities which are of significant scale relative to mine extries. Design and performance data on the suppression system and components are included. Flame front and pressure wave trajectories are plotted for several tests in which dust explosions were extinguished showing the operating time and the effects of the suppression system.
