Study and Application of Transportation Advance Hydraulic Support in Ventilation Roadway

High requirements of working face ends and advance support reliability were put forward under fast mining of fully mechanized coal mining working face. The transportation hydraulic support ZQ4000/20.6/45 has the following characters，such as high supporting strength，roof could be supported effectively and then roof could be avoid supported repetition，the surrounding rock deformation of roadway could be decreased. Safety mining and high production and high efficiency of working face could be realized with the advance support，it was promoted and applied in Shandong energy corporation，it references for similar situation in domestic.
