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 …

Therefore, for melt-cast explosives, DNTF can be used as an independent melt-cast explosive material, serving as both a carrier and a high-energy explosive. However, the mechanical sensitivity of DNTF is high (impact sensitivity H 50 = 20 cm), making it more sensitive than HMX (H 50 = 29 cm), which significantly limits the potential ...
