Abstract
One of the risk impacts of blasting activities is flyrock. The impact of flyrock can be minimized by evaluate the factors that influence flyrock such as blasting geometry. Flyrock cannot be completely eliminated but flyrock distance can be reduced to prevent damage. This study aims to determine the actual maximum flyrock distance in the field and the factors that influence the flyrock distance. This study was conducted at PT. Sims Jaya Kaltim, Paser Regency, East Kalimantan Province. This research was conducted 31 times and the average throwing distance was 79.8 meters, the actual maximum flyrock throwing distance was 134.3 meters and the minimum throw was 40.5 meters. In the flyrock throw prediction, the Richard & Moore calculation method was used with a face burst mechanism of 121.3 meters and cratering of 232.2 meters and the Ebrahim Ghasemi dimensional analysis method of 104.5 meters. From both methods, the Ebrahim Ghasemi method was found to be closest to the actual flyrock with a standard deviation of 29.49 meters and an error percentage of 2.90%. From the results of the correlation between the blasting parameters and the actual flyrock, it was found that the factors that influence the occurrence of flyrock are powder factors, so an analysis was carried out to obtain a maximum flyrock throwing distance of 90 meters so that the safe radius of the tool is 180 meters, then the maximum powder factor used is 0.14 kg/m3.
