Mining complex waste management | 3D lab tour
    Main tasks and objectives of the Laboratory in the mining complex waste management:
  • development of scientifically grounded proposals for efficient utilization of solid mineral mining and processing wastes;
  • formulation of recommendations on backfilling technologies for underground ore mines;
  • development and optimization of backfill mixtures based on locally available binders and aggregates (mainly, wastes);
  • validation of backfill mixture transportation methods;

  • The most important engineering solutions developed by the Laboratory:
  • development of gypsum-containing waste-based backfill mixtures and fabrication technology;
  • recommendations on the fabrication of hardening backfill mixtures for underground ore mines based on “mill-free” technology;
  • development of clinker-based and cement-free backfill mixtures;
  • validation of a new conception of ore mining and processing waste utilization in a chemically bound state and disposal to mined-out
  • areas of surface and underground ore mines. The Laboratory is furnished with modern equipment: for ore processing (crushers, grinders, vibratory cone and ball mills, thermostat, sieving machines); for studying of physical and chemical properties of minerals and mixtures (compression testing machines, ultrasound analyzer of the rock mass strength, laboratory-scale vibratory plate; construction material moisture meter, sclerometer, Vikat apparatus, core drilling device). The Laboratory is also furnished with a KBF 720 constant climate chamber for modeling of any underground conditions, accelerated climate tests for various industrial sectors).
