before loading into
the blast hole. In charging operations, each of the two
explosives (Explus and Nitram 9) was used as the
base charge in their individual holes, while ANFO
was used as a deck or column charge to enhance the
performance of each of these explosives in their respective
holes during charging operations. Electric
detonators were used with each respective charge.
The tonnages of blasted materials produced were recorded.
The weights of explosives consumed were
also recorded. The summary of the results is presented
in Table 5.
