    EVALUATING AND IMPROVING BLASTING RESULTS AT .

    One of the most frequently encountered requirements of mining operations in which rock is broken using bench blasting techniques, is the need to produce a well fragmented muck pile which will "dig" easily and to cause less environmental impact. In bench blasting, the realization of an economic and safe blasting is only possible with
