The second case is the mine that purchased the electronic detonators and, because they have the ability to be programmed to shoot very fast, are programmed to shoot very fast, This functions off outdated theories that shock breakage is a major breakage mechanism and that extremely fast shooting, row to row, will lead to better fragmentation or better throw, They then find that rocks are being violently thrown and might suffer increases in airblast
and cast percentages have dropped, and instead of blaming the caps or the fast timing, the powder company blames "unique geology" as the major cause of poor blasts.
The recent acquisition of an European manufacturer of a proven Airblast
defoliator system, the ERO engineers have developed a solution that allows the VITIpulse Airblast
heads to be attached in the early stages of the season for initial leaf removal and canopy cleaning and then, as the season progresses, the Airblast
heads are removed and the Roller heads installed with leaf removal without damage to canopy or fruit.

On April 8, 2014, two pesticide applicators were driving tractor-pulled airblast
sprayers to apply a mixture of pesticides to prevent psylla infestations in a pear orchard.
Calculators include: ground vibration prediction, airblast
prediction, powder factor, explosives per borehole, rock per borehole, scaled distance and borehole angle drift.
Another method is to expose the relatively slow moving liquid to a high velocity airstream as used in twin-fluid, air assist, or airblast
sprayer  for pesticide application in olive trees (see Figure 5(c)) consists of two vertical booms with four nozzles each.
Ammonia LPR systems have now been successfully applied to continuous airblast
freezing systems and to low-temperature cold stores with economized screw compressors where it had not previously been possible to take full advantage of the economizing.
