A rather common observation over the last several decades at least has been that rock or ore properties influence blasting results more than does the explosive type that has been used in the blast. It we accept that premise than it is held here that the material to be blasted should receive even closer attention as to its properties. Several years ago, Dr. Richard Ash published papers that pointed out the rock properties that mostly influence blasting. These principles are given attention in this paper. We have gone somewhat further - or lets say expanded this subject in regard to the role of rock structure in open pit blasting. Though open pit work is given some prominence, we believe that much can be observed and applied to underground mining.

Description of Project: Tamar Group’s civil division was awarded a contract to implode the Sun Hotel, an abandoned 14-story building located along Bat Yam’s coastline, roughly two kilometers south of Tel Aviv, Israel. On Nov. 6, 2012, Tamar Group’s experts positioned explosives in strategic locations of the building, targeting its central pillars, which then caused the building to collapse within seconds. Tamar Group used a relatively small amount of explosives in order to generate a well-controlled blast. This is the largest scale demolition carried out in Israel to date.
