Engineering Rock Blasting

The initiation system transfers the detonation signal from hole-to-hole at a precise time.

One of the groups of parameters that can be controlled by the technicians in blastings is that of the explosives. The selection of the type of explosive forms an important part of the blast design and, consequently, the obtainable results.

Before any blaster selects an explosive to be used for a particular task, one must determine which explosives would best suit the particular environment and the performance characteristics which will suit the economy of the job. Hence, it is appropriate that knowledge about properties of explosives is obtained so that type and quantity of explosives used can be decided based on its ability to function under the specified conditions and achieve the objectives efficiently.

In order to change the mechanical properties, as well as some of the thermal, output, or sensitivity properties, the pure explosives are often blended with other explosives and other chemically inactive materials so that can then be worked in various ways to form specific explosive products.
