CHAPTER – 1 INTRODUCTION
1.1 Background
1.1.1 Uses for Commercial Explosives
Commercial explosives are used in a number of applications, including coal mining, blasting of
rocks, etc. It is desirable that explosives combine their efficiency in executing certain work with
economy and safety. Many of the older types of explosives are based on NG (such as
Dynamites), but the trend in modern explosives has been to reduce the amount of NG by
replacing NG with other, less expensive components. The majority of modern commercial
explosives contain AN and some combustible material such as charcoal, coal, coal tar, or
petroleum products.
A typical example of a modern, inexpensive commercial explosive is the Ammonium Nitrate-Fuel
Oil (ANFO) described by Cook [1]. Many commercial explosives designed for certain types of
work may also be used for other purposes as detailed in Table 1-1 below.
