| Abstract In addition to the performance and safety factors in the rock production field, researchers look for open extend vision to the small contractors to solve their main problems, which are represented by the machines and explosive expense and availability [1]. In this work central blasting method was applied in various rock structures and geology in Sudan to know the opportunity of other alternative solutions of these sites problems. The mentioned rocks include black granite in White Nile, the white granite in Alseleet (Near Khartoum), and the marble in Atbara. Results show that this method solves the problem of preparations, drilling, primary blasting tasks efficiently according to the explosive amount and machines expenses. This method shows more cost in the stage of secondary blasting, comparing with the bench blasting methods, but this can be considered as a minor effect compared to the major advances of using this method. On other hand it was found that there were unacceptable sites to deal with the traditional bench blasting theory of Livingston, in these cases the central blasting theory becomes a unique absolutely solution. | ||||
