Optimize on the Ventilation System of Pedestrian Mountains and the Return Airway of 1930 Coal Third District after Connected

摘要

According to the production requirements and arrangements of 1930 coal, Third District pedestrian mountains and Third District return airway were communicated. And the ways that adding appropriate resistance in the mining area return air route, continue to increase resistance in the +1944m horizontal transport Shimen, taking iron damper instead of wood damper, adjusting the Third District wind turbine operating parameters, removing the temporary damper of the Second District 6# main transport roadway and so on were integrated optimization. The Third District ventilation system was formed. Meanwhile the ventilation system design experience and recommendation were summarized. The mine ventilation system would be stable and reliable and mine daily production would be safety.
