Blasting for Rescue Applications
The use of blasting to rescue entrapped persons has a long history. At the turn of the 20th century, mine collapses were unfortunately common. Major rescue efforts often involved drilling and blasting to reach trapped miners. In recent years, explosives have been used in at least one cave rescue effort in Europe and a successful mine rescue in Australia. Given the risks involved and limitations of high explosives however, blasting to remove obstacles is uncommon today. Advances in technology have opened up new possibilities for the cave or mine rescue team that should be considered. The wide availability of high-powered, battery-operated rock drills, non-detonating blasting cartridges and even small-scale micro blasting kits have opened up new options. In this paper, we survey the current state of these techniques, including their capabilities, limitations and the logistics of building a deployable capability for a rescue team.

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 firers vehicles and to mine infrastructure.
