The need to maintain the specified atmospheric parameters inside workings at performance of erection work is still critical even during the closing stages, i.e. when through-flow ventilation is already in place. This task is becoming especially important when vehicles and equipment driven by internal combustion engines are used in mining operations. Application of traditional ventilation schemes with fans located inside the tunnel does not seem rational as it decreases mobility of the mining and construction equipment. It is known that fans located at some distance from the brow and creating a free airflow directed perpendicular to the brow face are often used in tunnel fire tests. However, they do not provide any justified methods to select parameters of such fans. The investigation included complex theoretical and experimental studies. The resulting dependences render it possible to select ventilating equipment parameters for the ventilation schemes with the draught source located outside of the working.
