Figure 2. Drilling and blasting pattern with non-electric detonators (delays in ms) The other two faces were initiated using electronic detonators, which were programmed according to the time sequences shown in Figure 3. In each case, the same drilling pattern was used and a burn cut with three empty holes was applied. Figure 3.This paper presents an approach for developing accurate models to predict the fragmentation due to blasting. The approach makes use of drill monitoring data, which provides data throughout the(PDF) Application of softwares for drilling and
