Efficiency of ore concentration depends not only on the raw material quality characteristics, but also on the level of its stability over a long enough period of time (day, week, month). Necessary quality of ore from blocs of the different composition is achieved usually by the way of its selective dispatch. For these purposes the simple and complicated selective excavation of ore from blasted mining mass “breakage” is applied. The suggested mathematical model of compound-structural bloc processing allows to stabilize quality of raw material and to plan efficiently the volumes of dispatched qualitative ore and ore, sending at the averaging store-houses.
