The Gel Stem LR2 is a reagent used as a containment system for explosives.
When applied the reagent forms a self-supporting gel that is pumped by stabilised water into blast holes.
As the gel is blasted dust particles become airborne and flocculate in mid-air before falling to the ground.
The reagent can mitigate 98% of the pressure wave generated after detonation, which measures 3-5 metres per seconds.
This results in less fragmentation, lower powder factors, smaller holes and less oversize.
Rainstorm general manager Mason Trouchet said that combined with optimal blast hole design and drill patterns, the knock-on effect for miners is significant cost savings and increased safety with reduced oversize risk areas.
Trouchet said the stem is also easier to ...
