    History of Explosives and Blasting
    In the US and Canada alone, blasters use more than 6 billion pounds of explosives and 75 million detonators per year. Coal mining accounts for two-thirds of consumed explosives of which more than 80% of it is ANFO.

    Today, sophisticated explosive materials and new technologies are being utilized to improve the quality of life for all of us. Computers are used to: drill, log and monitor blastholes — automate blending and delivery with bulk trucks — determine bench heights and face conditions — analyze production efficiency, design blast patterns — and more.
