Abstract

Powder factor is comparison of usage amount ANFO with acquirement amount unload limestone with standard Pf between 0.20-0.30.the purpose of this study was to determine the effect on the results of fragmentation factor powder.the method of calculation methods RL,Ash.as for the data requieed the use of ANFO amount bullet holes the size of the fragmen number dismintling explosive results.the results foud that the powder factor is applied already meet the standard 0.20-0.30 kg/ton.then the result of the fragmentation value of 80 cm.from this study it can be concluded that the powder factor and blast fragmentation results already meet the standard the has been set.
