Abstract
The Bureau of Mines evaluated short-delay coal mine detonators manufactured by three domestic companies for electrostatic sensitivity, strength, and no-fire current level. Electrostatic sensitivity was studied in pin-to-pin and pin-to-case modes employing 10-kV potential. Strength of detonation was measured in the Bureau's underwater test facility. No-fire current was measured using a constant-current power supply unit. Test procedures and experimental data are included.
