This paper discusses the selection of supports of perpetual gateways in steeply inclined seams

and evaluates the support effects.Considering the characteristics of the present problems of the support method of gateways in complex surrounding rock in steeply inclined seams

laboratory scale modeling and numerical simulation are made and in situ tests are carried out.It is concluded that bolt-mesh-anchor is the most effective supporting measure for this sort of gateways.The effectiveness of practical application of this type of supporting structure is found to be satisfactory.The dynamic design method adopted in this paper provides a effective means of designing roadway support in deeply inclined seams.This study will be of reference value to other similar mines and is expected to find wide application.
