Drilling construction of north flank air shaft in Fenglong Colliery is very difficult due to occurring fractured zones in karst cave.The paper introduces grouting and blocking water using fly ash and rice husk and freezing technology construction,which obtains successful experience and has reference meaning for vertical shaft construction under similar complicated hydrogeological conditions.
