In focus of the article is operation of reinforced-concrete (adaptable) feeders and their advantages over other dischargers. The scope of the analysis also embraces the evolution of reinforced-concrete (adaptable) feeders and ways of improving their efficiency and safety in underground mining of hard minerals using the systems of caving and discharge under overlying formations.

The author proposes a number of ways to optimize adaptable reinforced-concrete feeders (RCF): Gradual transition from small to large discharge window; Mine management in operation of RCF; Methods to enhancing mine profit return in operation of RCF; Methods to reduce ore dilution in operation of RCF; Influence of mine-technical conditions on shape similarity factor in operation of RCF; Adaptation of current mining system with ore discharge by blasting to operation of RCF; Reequipment of RCF with semiconductor sensors for real-time data measurement, estimation and remote transfer.
