OREANDA-NEWS. "Polysaevskaya" coal mine of OJSC "SUEK-Kuzbass" has gone out into operation with new ?1747 lava with thewith removable capacity of course Breevsky of 1.6 meters and coal reserves of 2.1 million tons.

Total investment in the modernization of the enterprise amounted to 1.6 billion rubles.Total investments in the modernization of the enterprise amounted to 1.6 billion rubles.

This lava is unique for the coal mining industry. For the first time it runs a technology that allows coal mining without people involved. The system is based on joint developments of specialists from OJSC "SUEK-Kuzbass", MARCO (Germany) ? EICKHOFF (Germany).

Monitoring; and control of downhole equipment is managed by the operator from the nearby roadway through the use of multiple sensors mounted on the processor, power hydraulic roof supporters, as well as specialized cameras, including those operating in the infrared range.

A computer program is fully capable to automatically identify and produce the most efficient movement of the combine, bolt roof supports, process of downhole transport sector.

The main advantage of unmanned method of coal extraction is safety in the lava, the lack of human potential traumatic areas and better quality of extracted rock.

As developers say, such technology is only used at one other mine in the world - in Australia.

To operate this and other lavas at the mine, a new surface technology complex is introduced, that include pithead inclined shaft with the conveyor gallery, coal storage, and weight-house. A new conveyor line with a total length of five kilometers and width of 1200 mm is installed to transport the coal from the bottom of the warehouse.

The lava consists of 176 sections of mine roof supports FRS Glinik -12/25 (Poland) that is designed especially for the working parameters of the Berezovskiy source. The Polish equipment includes face conveyor FFC-9 Glinik, gate-end conveyer FSL-9 Glinik, swing-mobile device FBE-1200 Glinik, crushing plant FLB-10G Glinik, pumping stations. The lava is equipped with the SL 300 EICKHOFF (Germany) shearer.

Expected monthly load for open-pit bench - three hundred thousand tons of coal.
