Ventilation Technology for Long Distance Heading Face

The application of local ventilation technology for long distance heading face in single lane, double lane and multi-lane excavation is discussed in detail. The frequently-used local ventilation technology for long distance heading face is proposed in different layout forms of single lane, double lane and multi-lane under different engineering conditions of mine. And a simple method of selecting local ventilation is designed in order to improve the work efficiency of the project progress and maximize the use of limited space, and to provide the economic, safe and efficient mining technical support.
