Wall rock mass quality classification model based on extension theory and its application

Based on matter-element model and cluster analysis,an extension cluster prediction method for wall rock mass quality classification is proposed.In the method,the grade types and influence factors on rock mass quality are used to set up the classical and segment matter elements.A simple forecasting model of rock mass quality classification is established by applying the correlated functions of matter elements and extension sets.The predicting results of rock mass quality classification are obtained by applying cluster analysis.The results show that the prediction model of extension theory has excellent performance.This is a new method to predict wall rock mass quality classification and can be used in practical engineering.
