Support in Mine Gateway Technology of Gob-side Entry Retaining in Thin Coal Seam

Taking the track, haulage gate in Nantun Coal Mine thin coal seam 3602 working face as the engineering background, through the analysis of roadway deformation characteristic, gob-side entry retaining method is presented in this paper, the reasonable roadway supporting form and parameters are determined. Engineering practice shows that the means of support effect is significant, which retains roadway stability, reaches the expected requirements.
