PART I. CHEMICAL EXPLOSIVES INTRODUCTION
The average citizen in today's world gives little thought to the important role that commercial explosives play in our lives and how their use is linked to our standard of living and our way of life. Explosives provide the energy required to give us access to the vast resources of the earth for the advancement ofcivilization. To maintain our standard of living in the United States, every day 187,000 tons of concrete are mixed, 35 million paper clips are purchased, 21 million photographs are taken, using large quantities of silver, 80 pounds of

gold are used to fill 500,000 cavities, and 3.6 million light bulbs are purchased. It takes more than 40 different minerals to make a telephone, and 35 to make a color television. Even everyday products such as talcum powder, toothpaste, cosmetics, and medicines contain minerals, all of which must be mined using chemical explosives. 1•2 Without explosives the steel industry and our entire transportation system would not be possible. The generation of electricity has been largely dependent on coal, and coal mining today is still the largest consumer of industrial explosives. Rock quarrying for road building, and excavations for skyscrapers, tunnels, roads, pipelines, and utilities are direct beneficiaries of the labor saving use of explosives. COMMERCIAL EXPLOSIVES MARKET
The use of commercial explosives in the United States continued to expand during the 1990s, reaching a peak in 1998. Figure 31.1 shows the 1317
