Blasting is a process of breaking the rock mass to excavate the ore and materials. many open blasting operations are faced with the apparently conflicting requirements of providing large quantities of fragmented rock and of minimizing the amount of damage inflicted upon the surrounding slopes. The document describes three controlled blasting techniques used to limit overbreak when excavating rock: presplitting, trim blasting, and line drilling. presplitting involves drilling and simultaneously detonating a line of holes along the planned excavation boundary before production blasting to form a fracture plane.

Controlled blasting techniques like presplitting, smooth blasting, line drilling and cushion blasting are described for minimizing overbreak beyond design boundaries. blast measurements and calculations involving powder factor, loading density, and fragmentation distribution are also summarized. download as a pdf or view online for free. It discusses techniques like line drilling, trim blasting, smooth blasting, pre splitting, and accurate delay timing that help control overbreak, vibrations, and fractures. Factors like discontinuity sets, orientations, and slope dip can influence the success of blasting and potential for slope failures. the document provides illustrations of how different joint orientations can impact end break, back break, and the final slope face quality when blasting. 3. controlled blasting techniques free download as pdf file (.pdf), text file (.txt) or view presentation slides online. blast techniques.
