WALL CONTROL BLASTING TECHNIQUES
Wall failures are costly and often life threatening. The goal of efficient wall control blasting is to make transition from a well fragmented rock mass to an undamaged slope in as short a distance as possible. This can be quite challenging due to the many factors that influence wall damage. To develop efficient designs one must have a basic understanding of wall failure mechanisms as well as limitations of wall control procedures. In addition, it is imperative, design be precisely implemented, evaluated and refined on a continuous basis.
