Thermal conditioning of intake air and application of dual!duct air systems for pipeline ventilation of open pits
The authors present equations for the calculation of air instability energy deficiency in deep open pits in case of temperature inversions. The description is given of a new energy-saving method of prevention and destruction of temperature inversions in an open pit. Specifications of a pipeline ventilation system, with which this method is implemented, are also included. To reduce gas pollution of deep open pits it is proposed to use a ventilation system including a high-performance exhaust blower and a high-pressure forcing fan connected to a dual-duct
