OREANDA-NEWS. February 14, 2008. Kombinat KMAore, PLC – Kombinat KMAore goes forward in constructing the substructure for the stowing system. At the latest technical council specialists of the mine and the enterprise have taken a look at the issue of pumping out waters that emerge due to concentrated mine refuses filled into the developed cavities. At the moment, the flow of water in Shaft #3 is seen reaching 160 m3/hour, while the discharge capacity is 250 m3/hour, and once the stowing complex is commissioned the inflow of water is set to rise up to 450 m3/hour. This caused the emergence of an issue – that of pumping water up to the surface. A few remedies were suggested, and namely, increasing the power of the available underground pumping house, using the developed stall as water-collecting header either at the 125 m or at the 71 levels. The latter option was selected, as it requires less costs and time to be completed. Consequently, it was decided to install a new pumping house to pump out cooling water to the surface in Stall 1/15 South-East at the 71 m mark. The assignment to prepare engineering documentation has been forwarded to Moscow-based Federal State Unitary Enterprise Hyprotsvetmet.
