The powder factor defined as amount of blast powder per 1 cubic meter of the rock body has been taken as controlling parameter of the quarrying. In such process results of blasting operation effects on the system capacity and its running costs. Some numerical examples of the real quarry system have performed and are presented in the paper. %A Malewski, Jerzy %A Rink, Patrycja %P 175-180 %U http://www.miningscience.pwr.edu.pl/Qarrying-as-the-optimization-problem,59895,0,2.html
