Assessment of the effect of blasthole design parameters
113 In addition, it was found that a blasthole length of 15 m ensured optimum fragmentation, diminishing the costs of subsequent operations. Incrementing the blasthole diameter from 89 to 102 mm reduced the total unit cost by 0.091 $/m 3. Incrementing the burden and spacing by 0.25 m also decreased the total unit cost by 0.097 $/m 3.Quarry Site Best Practices Natural Stone Council,2009119 Stone quarrying, if executed without regard to surrounding ecosystems and geologic conditions, could disrupt the balance of wildlife, plant life, and water bodies in the area. For instance, removal of native vegetation coupled with alteration of topography can generate erosion problems, and site runoff can impact local waterways.blast design for stone quarries,Stones of Northeastern U.S.QuarryTypes. In fact, most of these pit quarries would blast away the top 20 or more feet of the top surface ledge due to its poor quality. Stone from these quarries was used for commercial and government buildings, public monuments, and other important stone edifices. Deep pit quarries are a postphenomenon.
