Abstract
Evaluation of blast performance is considered of high interest for mine operators to improve blasting results. Within the scope of this study, the aim is to determine the optimum blasting conditions in Tourah-quarry, Helwan, Egypt. Guidelines have been suggested for a step-by-step trial blasts to evaluate blasting results in Tourah quarry. Thirty full scale production blasting events in Tourah quarry have been conducted and the results have been recorded. Two design parameters have been investigated. These parameters are initiation point and primer location inside the blast hole. The objective has been achieving optimum blast results: adequately displaced and swelled muck pile; desired fragmentation degree; less uneven rock face and minimum environmental problems such as ground vibrations, and flying rock.
