讨论了综放沿空掘巷围岩的稳定性，并根据理论分析、实践经验和现场观测数据的整理分析，构造了综放沿空掘巷围岩稳定性影响因素的隶属函数，建立了灰色-模糊分类模型；实际应用表明，该模型准确、可靠，对于综放沿空掘巷的支护设计、施工和管理具有指导作用。

The stability of roadway driving along next goaf for fully-mechanized caving face is synthetically influenced by many factors such as intensity of surrounding rock, intensity of coal, mining depth, joint and crack of surrounding rock, mining operation, top coal thickness, width of pillar and roadway section. On the basis of theoretical analysis, practical experience and observation data, the subordination functions of the factors influencing the stability of roadway driving along next goaf for fully-mechanized caving face are structured and the grey-fuzzy classification model is established. The application of examples shows that the model is accurate and reliable, and plays an important part in the support design, construction and management of roadway driving along next goaf for fully-mechanized caving face.
