Given the depth of the mine and heating of the air due to both auto compression, the geothermal gradient and any diesel powered equipment in the mine, the temperature of the air at the bottom of the exhaust ventilation shaft will most likely be around 30 °C. The atmospheric pressure at a depth of 2735 m is, $P \ = \ 103\ 200\cdot e^{\frac{-9.8(28.9644)(-2735)}{1000(8.31446) (273.15+30)}}$ = $140\ 400\ Pa = 1404\ hPa = 20.37 \ psi$ [1]: https://weather.gc.ca/city/pages/on-127_metric_e.html
