Technical Examples

A mine ventilation structure is incorporated at the intersection of first and second intersecting passages in a mine. The ventilation structure comprises a tunnel-forming construction (e.g., a pair of side walls each walling off at least a portion of a respective mouth of a first passage and a deck spanning the side walls and connected thereto). The construction defines a tunnel establishing communication of air from the upstream to the downstream mouth of the second passage. An air deflector is located in the first passage adjacent the tunnel-forming construction for decreasing shock loss associated with the mine ventilation structure, thereby increasing the amount of air flow produced by the mine's ventilation system.
