| Abstract: | In fan-pattern medium-to-long hole blasting operations, there are several significant factors affecting the fragment size. In these factors, although otherwise often neglected, are discussed in detail corresponding measures are proposed to reudce oversized fragments. It is shown in field that these measures have achieved good performance in cutting down the oversized boulders rate. |
