Abstract

The length of the ore excavation block is very important parameter in the underground mining of mineral raw. With development of the technique for underground mining was change the length of the ore excavation block which in the last amount from 50 to 80 m with application of load and haul mechanization powered by compressed air, and today it amount from 300 to 500 m in the application of diesel powered mechanization for load and haul of the run of mine ore from stopes. Because this parameter defend from more factors it is necessity to work economic-mathematical model which help us to determine the optimal value for the length of excavation block for typical mining and geological condition.
