Abstract:
At present, Dynamite is currently manufactured only in a few countries as a commercial explosive due to its high cost hazardousness. Therefore import and supply
do not match the demand patterns which inevitably result in considerable inconvenience
to the quarry industrialists to certain degree affecting the development of this industry
which has a direct bearing on the country's infrastructure development. Consequently,
there is great necessity to manufacture high quality explosive of low cost and less
hazardousness as a substitute for Dynamite. By using Magnesium/micro glass
bubbles/ Aluminium, instead of the main sensitizer (Nitro Glycerin) of Dynamite, Slurry
explosives (Water-Gel) are manufactured under the similar process as a powerful
explosive. In this instance, the industrialists have been compelled to use the low cost but
almost untested explosive as a substitute. Research so far carried out only show that the
product is substandard which dictates further the investigation.
