2018-9-12 Flyrock is the undesirable throw of debris from a blast. Because flyrock can cause severe injury and property damage, shotfirers must take precautions to prevent it, especially if blasting occurs near property or people. Nearly all previous flyrock incidents could have been avoided.

2011-2-1 Research highlights In the paper a fuzzy model was developed to predict flyrock in the blasting operation of surface mining. Prediction of flyrock is very important in the mining industry. Empirical models have shown poor performance to do the task. This research has proved capability of the fuzzy model to predict flyrock accurately.

Flyrock is one of the most contentious issues in bench blasting. Unlike ground vibrations, flyrock has the propensity to cause fatality and severe injuries. Although the kinematic equations present a basis for the estimation of flyrock distance, these suffer from the drawback of ignoring the post-release effects of trajectory motion in air.

2015-9-8 Flyrock is a rock thrown to greater distance than desired and is a dangerous and unwanted phenomenon in surface mines, particularly, when blasting is proceeding close to human occupation and dwellings. The prediction of flyrock distance is critical in defining the statutory danger zone of blasting and has evaded blasters for quite some time. Control of flyrock with its distance prediction ...
