: Flyrocks–Detection and Mitigation at Construction Site in Blasting Operation. certain mitigation measures discussed to control this abnormal distance travel of flyrock. Most of flyrocks fall in the region that forms a semicircle in front of the face, Ludwiczak, (1985). These flyrock impacts cause craters or blownouts on the surface of bench.

The investigations in U. S. surface mining show a value of 25%, and the Indian mines show a proportion of 20% [5,6]. So it is important to study the reasons of flyrock and to seek counter measures. However, for the complicated mechanism, the flyrock is generally considered with experience in practice.
