Abstract
DRIFT is a program to design perimeter control blast rounds for typical underground drifting applications. The design utilizes current methods of perimeter blasting with the added design element of a buffer row coordinated with the perimeter row to reduce perimeter damage. The coordination is in applying one of several blast damage models to calculate the damage extent for each buffer and perimeter blast hole in the design. The calculated damage is then applied to the spacing between the buffer and perimeter blast holes. Underground blasting with perimeter damage control can reduce the requirement for loose rock scaling and reduce the risk of ground fall injury. The purpose of the DRIFT software is to provide the blast design engineer a tool for developing an initial conceptual blast design intended to meet design objectives. A program of field trials and blast design refinement is suggested until design objectives are met.
