Abstract
Observed flyrock distances for 47 blasts at six limestone quarries along wi th blast design parameters are presented. The influence of blasthole diamet er, burden, stemming length, powder factor, the condition of blastholes (dr y or wet) and the initiation systems on generation of flyrock is analysed a nd the most critical parameters for flyrock control are identified. Based o n the analysis of results, suggestions are given to minimise the flyrock ha zards at limestone quarries.
