The MTi Group’s STEMSTOPPA is a plastic blocking product used to stop stemming from penetrating the explosives column. It is designed to be lowered using a 600G DIPWEIGHT where it will stay on top of the explosive’s column.
The unique design allows it to sit flat on top of the explosives while the holes allow the explosives to gas as required. The STEMSTOPPA becomes a flat plate which does not allow any further ingress into the explosive’s column and resists force downwards.
Stemming loaded into the hole will land on this plug instead of penetrating into the explosive’s column. This guarantees better blasting with a clearly defined area of explosives and stemming.
