Abstract

In order to study the classification of surrounding rock stability and the reasonable selection of supporting parameters in coal seams of closed coal seams, the mechanical properties of surrounding rock of mines with similar geological conditions are selected as analysis samples, and based on fuzzy-cluster comprehensive evaluation method, the FCM tool function of Matlab software is used to study the classification of surrounding rock stability.Combined with the general situation of the mine, the optimization scheme of the roadway support parameters is proposed.The optimization scheme is verified by the surrounding rock deformation monitoring.The results show that the transportation lane of the mining area of Shenzhou Coal Industry belongs to class Ⅳ unstable roadway, and the results of fuzzy comprehensive evaluation have a reliable guiding role in the selection of roadway support parameters and surrounding rock deformation.
