Abstract：Deep air shaft in Pansan Mine affected by fault F47 ,and it has the stress concentration phe‐nomenon ,so it is easy to cause the damage of shaft wall and the loading chamber instability. For safe‐ty ,high efficiency through the section to adopt a series of composite reinforced support technology , smoothly through the fault fracture zone ,provides useful experience for the unstable formation in big section chamber construction.
