Mining and processing

Mining and Processing Department, together with specialists of other departments, performs design of:

- Mines, including the following topics:
  • calculation of recoverable reserves;
  • choice of mining method;
  • scheme of field opening;
  • correction of method of field opening and stocks exploration;
  • comparison of options for development of ore fields;
  • project of mining lease at the field;
  • definition of design capacity of the enterprise;
  • choice and justification of systems development;
  • designing the electricity sypply schemes for mines;
  • calculation of ventilation systems;
  • making decisions on drainage and dewatering;
  • implementation of complete automation of ore production and transport up to loading into railway wagons;
  • design of mines in the zones of permafrost and high seismicity;
  • exploitation of modern equipment and latest techniques to ensure the minessafety.
     
- Quarry (open-cast mining);

- Methods of increasing capacity of mining companies and technical upgrading, opening and preparation of land mine fields;

- Development of drilling, blasting and combined technologies for extraction of minerals;

- Construction and reconstruction of trunks, mining bunkers, batching plants, mine dewatering systems;

- Underground electric locomotive, conveyor and self-propelled transport;

- Underground capital yields, stems and horizons couplings, ore warehouses, garages, storages of fuels and lubricants, electromechanical workshops;

- Development of technologies of hydraulic and mechanical tabs of developed space;

- Ventilation of mines, underground installations of main ventilation fan, auxiliary fan systems;

- Surface mining complexes - pithead buildings, lifting machines buildings, main fan systems;

- Development of alluvial fields;

- Processing plants;

- Camps with life support systems;

- Warehouses: 
  • ore and nonmetallic materials; 
  • logistics; 
  • explosive materials (explosives); 
  • reagents (including high-toxic substances).
     

 

Mining and Processing Department together with the Economic Department develops:

- technical and economic assessment of choosing the best option for opening and working on the deposit with the assessment of capital costs for construction of enriching factory with tailings, as well as for infrastructure of the enterprise;

- feasibility study of temporary and permanent exploration condition with the calculation of reserves with a view to set / remove stocks of fields to/from the state balance, with the subsequent approval by SRC;

- feasibility study (draft) of mines and quarries construction;

- feasibility study of raw material base of enterprises;

- feasibility study for construction investments of quarry or mine;

- development of disturbed mining reclamation projects, man-made dumps concentrators and metallurgical industries.
