Prediction of flyrock throw distance in quarries by

 · The first step of flyrock control is the prediction of throw distance using operational blast parameters. Significant variations in rock mass may cause excessive and unexpected flyrock throw. According to Jimeno et al. ( 1995 ), intensely fissured and jointed rocks tend to create more flyrock than massive and homogenous rocks.

Flyrock - Wikipedia

Flyrock, or wild flyrock, is rock that is ejected from the blast site in a controlled explosion in mining operations. The term refers in particular to rock that flies beyond the blast site, causing injuries to people and damage to property. This is considered a significant issue in mining; between 1994 and 2022, 32 miners were injured by flyrock.
