Abstract: Based on comprehensive research methods of laboratory tests, numerical simulation calculation, field measurement and mechanics theory analysis, etc, this paper researches deformation mechanical characteristics and influencing factors of surrounding rock in deep mining roadway, classifies surrounding rock of deep mining roadway into overall classification by the fuzzy clustering method, and further classifies surrounding rock into sub-classification based on specific conditions of roadway roof and two-sidewalls. Afterwards, the paper proposes control principles which are suitable to maintain the stability of deep mining roadway.
