Meanwhile forward boring method is applied in the first colliery inclined shaft tunnel by shield- Shendong Bulianta colliery.Furthermore the forecast result is pared with the engineering geology database and shield residue.The results show that forward drilling method is an accuraey and intuitive method and it is suitable for colliery inclined shaft tunnel construction by shield.
