Stability Classification and Control Technology of Roadway Surrounding Rock in Jiaozuo Coal Mine

Due to the traditional supporting patterns and concept of roadway surrounding rock restrict the promotion of bolting technology in Jiaozuo coal lane,this paper adopted fuzzy clustering method to establish the stability classification of roadway surrounding rock under the geological conditions of production.The stability classification is divided into mid-stable class Ⅰ and unstable class Ⅱ,then the paper analyzed the rock deformation and control technology of roadway surrounding rock between mid-stable class and unstable class,identified the better support form and parameters in various types of roadway.
