Mar 19, 2020· The selection of appropriate blasting vibration limits for civil construction projects and quarry operations has a major influence on a project?s overall cost, duration, and environmental impact. In some cases, the application of an overly conservative limit may affect a project?s financial viability to a point where it may not even commence, despite passing all the relevant planning approvals.
Blasting, process of reducing a solid body, such as rock, to fragments by using an explosive. Conventional blasting operations include (1) drilling holes, (2) placing a charge and detonator in each hole, (3) detonating the charge, and (4) clearing away the broken material. Upon detonation, the

Jan 02, 2012· In the beginning, blasting was relatively simple. The explosive was placed in the holes and the holes were fired. The speed at which the fuse or an igniter cap would burn was the delay timing per explosive round along with different lengths equalling different times (Alfred Nobel, 1865). Electric pyrotechnic delay detonators (circa 1900) and cord initiating systems followed.
