What is shaft ventilation?

Shaft ventilation is a method of providing fresh air to underground mines or tunnels to maintain safe working and living conditions for workers. The ventilation system consists of a network of interconnected ducts, fans, and air doors that are used to distribute fresh air into areas where workers are present and remove contaminants and exhaust air out of the mine. The shaft ventilation system is an essential safety feature and is designed to control the flow of air to prevent the accumulation of toxic gases such as carbon monoxide and methane, which can be deadly. The system is also used to remove excess heat and humidity and control dust and fumes generated by underground activities. Ventilation shafts are typically located at the top of a mine and are designed to draw in fresh air from the outside. The system can also incorporate sensors to monitor air quality and ensure that the air is safe for workers to breathe.
