<p>This document specifies the procedure that shall be followed when a Contractor or Permittee is proposing to blast. By following this procedure, the Engineer-In-Charge or the Permit Engineer can help ensure that the Contractor accomplishes the work in a ...
The purpose of this study is to measure the size distribution of blasted rock using the digital image processing software “SplitDesktop system” in order to evaluate the efficiency of blasting operation. Site of study is a limestone quarry producing limestone ...
