· 1.. IntroductionExplosives are the primary source of energy for rock breaking in the mining, quarrying and construction industries. The work into which the energy is converted transforms rock into a distribution of fragments and displaces them so that they can be conveniently loaded and hauled for further comminution and processing.
· Like Salem Stone Corporation cited above, most quarry companies consider themselves in the people business first. One example of a blast would use diameter vertical holes, sink explosives 50 feet deep with rocks above the blasting material and place them around 15 to 20 feet apart.

The Explosives Supervisor must be familiar with the quarry and the specific shotfiring rules for the quarry as it relates to the safe use of explosives. The Explosives Supervisor must prepare the blast specifiion for a specific blast which includes an assessment of the risks and an identifiion of the danger zone.
· Abstract Five major environmental effects of rock blasting are ground vibrations, airblast, flyrock, dust and fumes. What makes them {open_quotes}environmental {close_quotes} as opposed to occupational health and safety issues is that their impacts are felt off the mine, quarry or construction site.
· A new concept in the quarry is also emerging, according to Gobbett. "A single multiple wire machine, the Pellegrini Meccanica Polywire, can be put not only in processing areas, but also in the quarry, even outdoors," he said. "This machine can slab any type of stone block.
· No drilling and blasting operation is perfect. Mistakes will undoubtedly be made from time to time, but some are more costly than others. Here are four that will ultimately impact your bottom line and cut into profits. 1. POWDER FACTOR DESIGN The costliest mistake companies make in their blasting is using a powder factorbased blast design.

However, most of the material is relevant to the design of any quarry for the recovery of construction and industrial minerals, anywhere in the World. In this edition, specific information on the UK planning system has been removed from the main text (principally in . Chapter 1) and replaced with more
The blasting specifiion should take account of: (i) experience gained from previous blasts at the quarry; (ii) any unusual circumstances which are present or likely to arise; and (iii) the design of the excavation. The blast specifiion should record information on: The loion of the area to be blasted in the quarry;
· The term Air over Pressure (air blast) is often used to describe the air waves, which are generated by blasting activities. Oriard (2002) simply defines this as the pressure above the atmospheric pressure. Air waves are compressed waves that travel through the air.
