Enterprise integrated design from feasibility study to design documentation for permafrost and seismic conditions is completed. Supervision is in progress. Different options of open pit configuration which enable operative response to modified market conditions were developed with computer modelling. Special design was developed for open pit mining in dormant underground mine conditions. To ensure enterprise safety and to decrease CAPEX and OPEX, research institutions were involved in the design. This enabled to decrease mined rock excavation and stockpiling volumes, employ local materials to arrange tailings dam, provide quarry reclamation by a complex of underground mine with conveyor transportation of overburden to dumps.
Unique crushing and grinding equipment unraveled in Russia is designed for gold-extraction plant. Ore transportation to plant is performed with main conveyor laid in tunnel inside mountain mass.
The project provides for tailings with face area over 10 km2
and dam over 100 m high.
Bypass channel over 22 km long is designed for Intrigan river diversion.
The design also includes over 300 infrastructure surface facilities including explosives, highly toxic substances stores, boiler stations, test laboratories as well as rotators' camp for over 2000 inhabitants.
All necessary approvals have been received for Project Documentation as well as for separate facilities:
- FAE Glavgosexpertiza;
- Safety Audit;
- Approval of Central Committee for Solid Mineral Deposits Development of Rosnedra;
- Safety and Health Certificate;
- Approval of Federal Agency for Fisheries;
- Environmental Seal of Approval for Waste Disposal Facilities (dumps, tailing, waste dump).
The design solutions have also acquired positive opinions of independent experts such as SRK Consulting (SA), Micon International Ltd (Canada), SNC-Lavalin (Canada).
