Abstract
A mine ventilation system and method are provided for continuously supplying fresher air to an automated mining machine located in a mine heading. A blower attached to a mining machine operates to suck fresher air into the heading from a tunnel with through ventilation and to exhaust the air out of the heading through a collapsible duct. A standby blower is provided which is activated should the machine blower not be functioning for whatever reason. This blower draws fresher air from the tunnel with through ventilation and blows it out through the collapsible duct, in a direction opposite to the normal air flow, and into the heading. The standby blower is located in the tunnel downstream of the heading and has an intake duct with an inlet upstream of the heading.
