APPLICATION OF VOKD AND VOD PLANTS

Main ventilation fan units of VOD and VOKD types are located on the surface at the mouths of ventilation shafts and consist of two independent fan units (one of which is a standby unit) and a set of transfer facilities from the operating fan to the standby unit by the automatic control system of the fan unit. The VOKD unit also includes an air reversal kit.

design of VOKD and VOD units

Shaft covers of mine ventilation units are of the falling, vertical or horizontal guillotine type, or in the form of louver dampers, self-propelled by type of door or as a vertical suspended door moving on rails.

The design of the shaft cover is chosen depending on the conditions (temperature, humidity, etc.) in which it will operate. Winches, screw mechanisms, or geared drives are used for lifting (lowering) or opening (closing) the shaft covers.
