For someone wanting to get a blaster's license, this book would be very valuable and even for experienced blasters and explosives workers, it is an excellent reference book to have/5(9).

The unrivaled, definitive reference for almost 40 years, this Mining explosives book work on explosives is now in its seventh, completely revised and updated edition. Some monographic entries, arranged alphabetically, consider the physicochemical properties, production methods, and safe applications of over explosive s: 1.

The art of blasting was of prime importance to mining because explosives enabled miners to move through solid rock as no other technology could. This book presents a detailed look at the whole process of using explosives, from drilling blast-holes to setting off the charges, with an emphasis on technology, material culture, and the impacts to.

“Explosives” is a concise handbook covering Mining explosives book entire field of ex-plosives. It was preceded by the booklet “Explosivstoffe” published in by WASAG, Berlin, and by the handbook of industrial and military explosives published by WASAG-CHEMIE in under the same name.

The book is a thematic history of explosives. The largest coverage is for gun powder detailing the history of its use in guns, bombs, rockets and mining.

Then the further advances of explosives are covered up to and including nuclear explosives. The author presents a technical work easily understood by this s: 8. High VOD explosives are more suitable in hard rock and low VOD in softer rock. Generally, explosives with a lower VOD tend to release gas over a longer period and consequently have more ‘heave’.

The VOD range in commercial explosives is m/s. Density The density of a explosive determines the charge weight per meter of hole. Mining industry response to the book continues to be incredible. Thanks in large part to the efforts by John Chadwick of the Mining Journal,and many other members of the mining community, the Hard Rock Miner’s Handbook has been distributed to over countries worldwide.

Web hits and downloads continue as students and. Well, yes and no. From the ninth century AD (though the historians are still uncertain about the exact date of its invention) to the mids, black powder was the only explosive available.

A general theory of explosives is that the detonation of the explosives charge causes a high-velocity shock wave and a tremendous release of gas. The shock wave cracks and crushes the rock near the explosives and creates thousands of cracks in the rock. These cracks are then filled with the expanding gases.

Explosives are chemical mixtures or compounds that, when subjected to heat, impact, or shock, are capable of undergoing a rapid decomposition that releases heat and gases, which, in turn, expand to form high pressures.
