Construction Planning, Equipment, CHAPTER BLASTING ROCK

BLASTING ROCK ENCE 420 ©Assakkaf Slide No. 4 INTRODUCTION ”Blasting" is performed to break rock so that it may be quarried for processing in an aggregate production operation, or to excavate a right-of-way. Blasting is accomplished by discharging an explosive that has either been placed in an unconfined manner, such as mud capping boulders, or is confined as in a borehole. CHAPTER 13
