DAILY PLANNING AND OPTIMIZATION OF RAW MATERIAL FLOWS IN FERROUS METALLURGY

At present, in coal mines, with a high speed of advancement of long working faces, problems of ensuring the safety of mining operations arise due to the rapidly changing geomechanical situation. In the case of pillar mining, the growth of the load on the working faces is restrained by the unsatisfactory condition of the workings, which are protected by coal pillars, the condition of intersections, junctions, and also auxiliary inclined workings within the limits of the working pillar.
