Abstract:  Based on the calculation formula of the anchorage force of a single resin bolt,this paper explores the relationship between the anchorage force and anchorage length of resin bolt and the wall thickness of coal mine shaft,and derives the checking formula of shaft wall thickness based on the design anchorage force of resin bolt.At the same time,this paper discusses the wall thickness of shaft wall and the relevant specifications when using resin bolt to fix shaft equipment in general conditions in the form of a case.
