Effective Blast Containment
STEMGEL’S™ powerful energy-attenuating properties result in 98% of blast pressure being attenuated and reflected back into the formation from the stem deck. This results in higher oscillating pressure waves with greater max positive pressure than aggregate stemming.
The outcome in Open Cut situations is a better controlled blast with substantially increased micro fracturing and breakage.
Blast holes stemmed with STEMGEL™ hydrogel result in the ejection of water vapour. The overall damping effect of STEMGEL™ when coupled with the explosive and walls of the blast hole, decreases noise, dust and air over pressure vibrations, resulting in a water vapor ejection and minimising fly rock risk.
Consistent Stemming Control
The consistency of the hydrogel matrix in STEMGEL™ also enables engineers to determine a constant value from the pressure wave attenuation and reflection.
When replacing aggregate as stem, STEMGEL™ can be loaded with lower stemming deck horizons so that users can recalibrate the depth of burial levels to increase the height of the explosive in the hole and decrease the stemming deck, all while achieving greater fragmentation.
SHOCKWAVE’s Specialised Gel Drive dose units will deliver STEMGEL™ into a blast hole up to 50 metres from the truck making it ideal for stemming contour and pipeline blasting.
Strata Decking
STEMGEL’S™ powerful attenuating properties make it effective for Strata Decking where a layer of STEMGEL™ between explosive layers, provides a ‘constant’ material that successfully attenuates pressure waves resulting in greater control and accuracy at each layer of the formation.
Down Hole Water Control
DHDA Down Hole Dewatering Agent solves down hole water and dynamic water ingress easily and acts as another layer of energy-attenuating stem to further increase the effectiveness of a blast.
Suitable for a toe stem deck, a level and accessible bench for the next drill and blast process.
