NWPC Commissions Main Fan Unit No. 2

North-Western Phosphorous Company (NWPC), a member of Acron Group, commissioned the main fan unit No. 2 (MFU No. 2) at the Oleniy Ruchey mine. Investments in this important facility exceeded RUB 1 billion (over USD 12.5 million).

The unit with fresh air supply capacity of approximately 500 m3/s provides underground ventilation during the operation of the second stage of the underground mine. The MFU uses reversible axial single-stage fans, with the fan and heater units located in the same facility and designed to supply the underground mine with fresh air at a specific temperature, ensuring the safety and comfort of miners. A separate haulage tunnel was excavated at a depth of 100 metres to operate the MFU.

Commissioning of the MFU No. 2 enable the mine to increase capacity to 6 million tonnes of ore per year, ensure the hoisting of mining personnel and materials, as well as provide for a temporary mine drainage system for further mining operations at lower levels until the main drainage complex is launched 200 metres below ground.
