MODELING BLAST MOVEMENT FOR GRADE CONTROL

During the blast the ore type materials within the pre-blast dig lines are displaced by various distances and directions to new locations, (Thornton, 2009a). The broken material also occupies a larger volume than it did before the blast due to the creation of void space between fragments. Thus, following the blast, the pre-blast dig lines contain a mixture of ore types and waste and no longer ...
