#0183;#32;Conclusions Destress blasting is an important technique for managing hazards of strainbursts due to excessive mining induced stresses. The technique can be applied either as a proactive measure or as a preconditioning. The difficulty and challenges with destress blasting application is that triggering mechanism of rock bursts are yet to be known.
Innovative blasting techniques and technologies. The aim of the modules, according to Dr Sharpe, is to make relevant topics, concerning rock blasting, accessible to all. They focus on the quot;needtoknowsquot; of rock blasting by being quantitative, but removing all the mathematical elements from this type of
blasting 1. blasting most basic unit operation of any mining activity 2. objective rock is blasted either to break in to smaller pieces such as in most mining and quarrying operations or large blocks for dimensional stone mining and some civil engineering application, or to create space.

blasting of cornices increases efficiency, boring holes along the presumed tension line exposes the avalanche blaster to considerable danger. Safety in borehole blasting depends critically on: 1. The blasting crews ability to judge correctly the safe working line. techniques for working with this high explosive (See Chapter 5 Detonating Cord)..
