Abstract: For special geological conditions of mudstone in shale surrounding rock through auxiliary inclined shaft of Simingshan coal mine and on the basis of analyzing auxiliary inclined shaft deformation, supporting scheme of pipe-shed grouting, pipe-shed grouting, U-steel ribs support was adopted. The engineering practice shows that the integrity of supporting structure and carrying capacity were effectively improved through the supporting scheme, with ensuring drive speed of the shaft, it also provides the reference of support technology for the similar condition shaft.

Key words: broken surrounding rocks, pipe-shed grouting, full length g routed anchor, coupling support
