Abstract：A designed length of No.620 Adit in Jiyuan Mine was 4 814.3m and the adit and the mine main and auxiliary inclined shaft were connected with a end to end forward heading method.Before the connection completed ,the adit was ventilated with a large diameter flexible duct forced local ventila-tion technology with a single fan.A FBD №7.1/2 × 45kW mode Local fan was applied with φ800 ~φ1 000mm ventilation duct.With relevant matched measures and enhanced ventilation management ,a max one-way ventilation distance was 4 587.3m and broken a limit of a single roadway one-way head-ing with a ventilation distance not over 3 500m with a single fan.Thus the ventilation requirements and the construction safety were ensured during the adit heading period.
