Quarry Blasting Lowering Fines

CHAPTER 2 LITERATURE REVIEW CHAPTER 2 LITERATURE REVIEW 2 1 GENERAL equipment and to achieve lower quantities of quarry fines Jeffrey et al (2003) found that the generation of quarry fines is due but the stages of blasting are considered as the most liable in generating such fines The amount of dust produced duringFIRING PATTERNS AND ITS EFFECT ON MUCKPILE SHAPE the efficacy of drilling and blasting operations for enhancing the fragmentation which in turn affects the downstream operations Quarry-A The annual production of Quarry was over 3 million tonne of limestone The geology of the deposit was quite difficult owing to frequent shaly and clayey intrusionsNews about the J P Carrara Sons Quarry neighborhoodThe permit allows Carrara to increase the total weight of each blasting event from 2 500 pounds to 6 500 pounds lower the depth of the quarry from 70 to 175 below ground level No blasting events had occurred at the quarry for more than a year as Carrara and neighbors battled their prospective cases in
