Abstract
In order to analyze the impact factors of slip strength in clamp devices for tunnel rigs in coal mine comprehensively and quantitatively, a multi-factor and hierarchy index system with 13 indexes were established, including 4 fields of driller, construction characters, technology and environment. Fuzzy Analysis Hierarchy Process (FAHP) was used to analyze slip strength. A simple method to construct fuzzy consensus matrix was introduced to obtain the weight of different factors. Result shows that FAHP is validated to be used in slip strength impact analysis.
