Stemming plugs improve blasting, productivity – Quarry
2007-2-1 Typically, the loss of explosive energy through stemming ejection reduces the performance of the blast. The fundamental theory promoting the use of stemming enhancement plugs is that they could potentially improve the effectiveness of stemming material in the blast hole. This would, in turn, better contain the explosives energy within the rock mass, and yield a more controlled and efficient ...
