Stability Classification of Roadway Surrounding Rock Cased on Fuzzy Comprehensive Evaluation

Abstract

In order to effectively predict the stability of roadway surrounding rock, a reasonable and effective support scheme was proposed. Fuzzy clustering analysis was introduced to classify the stability of roadway surrounding rock. Based on the data processing of 7 classification indexes, the weight and subordination degree of surrounding rock indexes of roadway are established. The results show that the upper roadway of No. 111070 is a Class IV unstable roadway. The research results can provide a certain reference for the subsequent determination of the stability classification of roadway surrounding rock.
