Study on the classification and supporting of the surrounding rock of the gateway based on fuzzy clustering

The surrounding rock of the gateway in Xishimen Iron Ore Mine has been broken very terribly. The deformation of them was very complex. we analysed the stability influencing factors of the gateways' surrounding rock and chose the indexes of classification.we built a programme in VB6.0 language to classify the surrounding rock of the gateways in Xishimen Iron Ore Mine based on the theory of fuzzy clustering.Considering the classification results, then researched how to support the surrounding rock. According to different classifications, we put forward the corresponding methods to support them.
