• Description:
  NIOSH has recently concluded an extensive blasting research and development program. One objective was to develop practical tools that encourage and facilitate the use of perimeter control in drift driving. NIOSH research suggests that proper design of the buffer row of the blastholes is the key to successful perimeter control. Specifically, if the buffer row of holes has been properly designed, the perimeter row of holes simply will do the final smoothing and shaping. Three blast damage models are presented and two blast design examples are described using model predictions. The paper concludes with recommendations for collecting the field experience to determine the optimum practical damage radius. [Description provided by NIOSH]
