Trench blasting and blasting where bench heights are small compared with the burden usually provide the greatest potential for flyrock because the degree of confinement and the specific charge are both high, and the charge is sometimes placed ...

mining engineering: Flyrock Phenomena And Area .

This paper presents the results of the research study on flyrock phenomena and blast area security related accidents in surface mining. The study revealed that a total of 45 fatal and 367 non-fatal accidents in coal, metal and non-metal surface mines had occurred between 1978 and 1998 where the primary causes were the lack of blast area security, flyrock, premature blast, and misfires.Working to Protect Your Community and Environment FLYROCK .can occur, as a general rule, in the mining industry it is accepted that the probability of flyrock can be reduced by careful control but not eliminated completely.
