A blasting system using the global positioning system (GPS) for timing the detonations for a shaped blast. The blasting system includes a master station including a master GPS receiver for determining
Current techniques for forming a large number of perforations or holes in a composite laminate can be time consuming, labor intensive and expensive. In one technique, tooling referred to as pin mats is used to create holes as individual fabric plies are pressed over and around the pins, and ...

Though all these ill effects can't be completely eliminated but adopting\ncontrolled blasting techniques can minimize these to tolerable levels. It is recognized that ground\nvibrations resulting from rock blasting below water near dam may endanger the safety of earthen dams.\nTherefore, controlled ...
This was an extremely complex blast which required the use of a number of different types of packaged explosives, as well as special timing techniques only made possible by using electronic initiating systems. This type of blast is high risk, and is more typical of a building demolition in ...
techniques may be used such as cleaning, abrading, scraping, physical removal of a thin layer of the target surface material, burning off by heat, adding reactive chemicals to remove a thin layer of the target surface material (e.g. acid wash). Some techniques may involve more than one “...
