Abstract: Cientific and reasonable classification for mining methods are conducive to the categorization of future mining methods and the development of basic theory of mining.However,the current classification of mining method is questionable.Therefore,in this paper,considering the development history of mining method,various classification principles were discussed,some problems in the classification were demon-strated, discussed and dealt with.Finally,a modified classification principle of mining methods was developed,and the current classification table of mining methods was improved.The results show that (1)the classifi-cation process should be based on the underground pressure management,the coupled method should be re-moved from the classification table of mining methods,pillar mining method and pillar filling mining method are both belong to the categorization of filling mining method,and the classification of some subsequent filling methods should be performed by considering the role that the filling body plays (i.e.,ground stress control or goaf treatment);(2) the belonging of the open stoping method with delayed filling should be based on the actual situation,the combined mining method should be involved in the three mining methods,the coupled mining method should be separately classified,and the explosive ore-handling mining method was not an inde-pendent method;(3)the classification of mining methods should be performed by considering the ground stress control methods,and a improved classification table of mining methods can be obtained based on the properties of various mining methods.
