controlling damage due to blasting. INTRODUCTION In recent years, highwall/spoilbank failures in the surface mines have resulted in significant loss to human lives, property, and production. A highwall is always changing as the process of extracting coal or ore continues. The challenge, therefore, is to maintain a stable highwall throughout the

processes As noted earlier, better blasting can strongly improve downstream mining processes. "As one of the rst steps in the mining process, blasting is widely understood to bear considerable inuence over subsequent stages," suggests Dyno Nobel''s Lamont. "The
· Rock blasting is the rock excavation technique most widely adopted in the various fields of the mining and con struction industries because of its economical and efficient aspects [1]. In surface mines and quarries, the main objective is to exact the largest possible quantity at minimum cost.
Blasting is a key activity in the mining cycle, commonly used in both open pit and underground mines to fragment the rock mass into rock boulders that can be handled by mine equipment. The resulting range of blasted block size distribution (BBSD) has important impliions on downstream processes, including the energy consumption and productivity of crushing and grinding systems [ 1, 2 ].
