ABSTRACT The main targets of the civil explosives applied in rock production area, are controlling of fly rocks as safety value and controlling of fragmentations size as performance value. These targets are achieved throughout the studying and analyzing of the effective factors such as density and type of explosive, type of rock, diameter of drilling, and depth of burial. This work deals with improving performance and safety of used civil explosives in production of rocks of different types and applications in the Sudan. This includes marble site in Atbara, diorite site in Alseleet, and granite site in Kassala. It is found that the tables and references of blasting design, like Langforce tables of standards, can be replaced by the tables found by this study as a reliable data. The economical analysis shows the main gain of this work.
