Banging on about liquid explosives
Mining using explosives is an effective but dangerous business.
We’ve come a long way since the days of sticks of red TNT - these days it’s all about liquid explosives pumped into the ground. These explosives need to be stable or explosions can go sideways.
This project is working in conjunction with ORICA Pty Ltd to determine the impact of movement and contamination by particles on the stability of explosives. The type of liquid mixture used in explosives is an emulsion (oil droplets suspended in water). This has been recreated on a laboratory scale in both static and dynamic systems, with variations to: particle type, pH, oil and salt types.
These tests allow us to determine what impacts these changes will have on an explosion and how to create more stable explosives.
