B Blasting activities at the Partolang Pit face problems, namely the size of thefragmentation results of the blasting that do not comply with company standards orproduce boulder. The size of the rock fragmentation required by the company mustbe no larger than the dimensions of the Excavator 6015B bucket dimensions with acapacity of 8.6 m3 and an opening size of 10 cm grizzly feeder. This research wasconducted to analyze ore and waste fragmentation using quantitative analysis.Geometry data was analyzed theoretically using the R.L. equation. Ash andcompared to the actual geometry and plans. The results of photo analysis of rockfragmentation on average ore obtained that the value of material that passes the 10cm sieve is 71% powersieve software, and 30.4% for Split Desktop software for thetheoretical value of the average fragmentation that passes the 10 cm sieve obtainedan actual value of 27.2%. and 26.5% plan which means the size of fragmentationat PT.BKP is not good. For material waste, the value of theoretical fragmentationand image analysis that passes the sieve is 100%. Geometry simulations werecarried out to overcome bad ore fragmentation with a burden of 3.25 m, spacing of3.90 m, stemming of 2.28 m, depth of 7.00 m, column infill of 4.72 m which resultedin fragmentation of rock passing a 10 cm sieve of 80%.
