Informational Bulletin An unexplained explosion occurred on a shotfirers light vehicle that was carrying boosters and detonators. This resulted in the injury of a mine employee and substantial damage to the vehicle.
Shot firers injured by air blasts Two serious incidents have occurred recently in Tasmanian mines, where shot firers and their assistants have been injured by an air blast. Both incidents could easily have resulted in serious injuries or fatalities; and both caused significant damage to the shot firersí vehicles and to mine infrastructure.
Blaster Training Module 4 This module presents aspects of surface drilling that are important to blasting operations. The purpose of drilling into rock is to provide a "blasthole" into which explosives can be loaded.
Blaster Training Module 6 This module presents information regarding fundamental rock properties and the geologic structures encountered during blasting operations. Geology can vary widely and has a great impact on drilling and blasting efficiencies.
Blaster Training Module 7 This module presents current blasting and related explosives regulations and identifies the regulatory agencies that enforce them.
Blaster Training Module 8 This module addresses the control of offsite impacts that result from blasting, namely: vibrations, airblast, and flyrock.
Fragmentation An effective blasting solution has been identified that enables the safe utilisation of powder factors several times higher than those used conventionally to provide significant improvements in fragmentation.
